Tips for Advanced Distillers – Advanced distillers should consider adding 2tsp of gypsum (CaSO4) to the mash water and adjusting the pH of mash water to somewhere between 5.8 and 6.0 before adding any ingredients. After adding gypsum, add citric or tartaric acid to adjust the pH of the mash water downward.
- If the pH needs adjusted upward, add calcium carbonate (CaCO3).
- A second trick for advanced distillers is using tincture of iodine to determine if all starches have been completely converted into sugar.
- Drip a few drops of the clear yellow liquid (not the solids) from the top of the mash (after the 90 minute rest) onto a white plate.
Drip a drop or two of the tincture of iodine onto the sample on plate. If it turns blue, there is still starch in the mixture. Rest it longer. Discard the sample. Here’s some additional information if you’re unclear on how much yeast to use for moonshine mash,

What does gypsum do for moonshine?
Description – Gypsum (calcium sulfate) additive is used in the distilling and brewing community to put calcium ions back into distilled or reverse osmosis purified water. Can also be used to lower pH of water, wort, or mash. Used in de-mineralized or soft to medium hard water to increase permanent hardness.
- When used as directed, gypsum is effective in eliminating the variations of composition encountered in water from common surface sources.
- Establishing the proper pH of the mash and the wort and providing sufficient calcium ions essential for enzyme function, kettle protein coagulation and yeast metabolism.
In beer brewing, calcium sulfate gypsum is added to the brewing water to adjust the water chemistry and enhance hop flavor. In distilling, gypsum is added to the wash (the mixture of water, grains, and yeast used to produce spirits) to increase the ionic content, which can improve the flavors of the final product.
However, the use of gypsum should be done in moderation, as too much can lead to an undesired taste. Dosage Guide Prepare a 1% solution of cold water and gypsum in a separate tank with vigorous mixing. Calcium salts are more soluble in cold water, and the hard mixing will help dissolve the salt more completely.
Dilute the gypsum solution into water being heated for mashing or for sparging. The final concentration of salts should be in the range of 100 to 1000 ppm (mg/L). This will require 0.025 – 0.25 lb/Bbl (10 to 100 g/hl). If a tank is not available for making the solution ahead of time, the gypsum can be also added directly to the mash or sparge water with as much mixing as possible to disperse correctly.
How much gypsum do I add to mash?
Mash pH is a crucial factor in the beer brewing process. You can adjust the mash pH by adding salts to the water or mash. One of the most popular salts for this purpose is gypsum. You will need about 0.5-2 tsp of gypsum to lower your mash pH. The exact quantity should be based on your water parameters.
When should you apply gypsum?
What Are the Benefits of Gypsum? – Using gypsum can improve soil structure, decrease soil compaction, decrease acidity, prevent water run-off, increase airflow and dislodge salt. It is a source of calcium and sulfur, which are essential for healthy plant growth.
It’s natural and non-toxic, so it’s pet-safe and safe for you to handle without protective equipment like masks or gloves. Gypsum contains calcium, which helps to improve soil structure. It aids in the flocculation process, which groups soil particles into clusters and improves air and water movement through the soil for healthy root growth.
Ice-melting chemicals such as salt damage lawns because they displace other elements necessary to a lawn’s health. Salt can prevent plants from absorbing the water they need and create drought-like effects in a lawn even when significant moisture is present.
- Gypsum can help to leach salt from the soil,
- Leaching is a process that uses water to drain salt from the root layer of a lawn to deeper layers of soil that do not interfere with plant growth.
- Gypsum supplies calcium to the soil.
- The calcium displaces sodium so it can be leached with rainfall or irrigation water.
The best way to use gypsum for the leaching process is to apply it after lawn aeration. Aeration creates small holes that make it easier for gypsum to enter and work within the soil. Gypsum can also neutralize your lawn when pet urine threatens its health. 
How often do you add gypsum?
Gypsum may be applied any time of year and, depending on the needs of your particular lawn, we may apply it two to three times a year.
Why add gypsum?
February 6, 2019 – Susan V. Fisk Warren Dick has worked with gypsum for more than two decades. You’d think he’d be an expert on drywall and plastering because both are made from gypsum. But the use of gypsum that Dick studies might be unfamiliar to you: on farmland.
Gypsum is a good source of both calcium and sulfur, which crops need for good yields,” says Dick. “We also found that it improves many other soil characteristics. Gypsum helps soil better absorb water and reduces erosion. It also cuts down on phosphorus movement from soils to lakes and streams and improves the quality of various fruits and vegetables, among other benefits.” Gypsum is a mineral that is naturally found concentrated in various places and can be mined out of the ground.
But Dick’s research focuses on gypsum recovered from coal-fired electricity generating power plants. Gypsum that comes from coal plants is called flue-gas desulfurization gypsum, as it comes from the process that ‘scrubs’ sulfur out of the smoke stacks to reduce air pollution.
- The gypsum that is recovered has good quality,” says Dick.
- The gypsum particles are small and uniform in size making them quite reactive.
- This can be a real benefit in agriculture.
- We also determined that it is safe for agricultural use through many studies.
- Reusing it for agricultural purposes, instead of putting it in landfills, provides multiple wins.” Gypsum is high in both calcium and sulfur.
In addition, the chemical formula of gypsum makes those nutrients more available to plants than some other common sources of these nutrients. Chemically speaking, gypsum is calcium sulfate, Its use is often confused with that of lime, which is calcium carbonate,
Gypsum will change soil pH very slightly, yet it can promote better root development of crops, especially in acid soils, even without a big pH change. This is because the gypsum counteracts the toxic effect of soluble aluminum on root development. Aluminum occurs naturally in soil and often isn’t a problem for crops.
4 things beginner moonshiners should do right away
But when soil becomes acidic, the aluminum is available to plants—and it can stunt or kill them. Another bonus of gypsum is that it is a moderately-soluble mineral. This means the calcium can move further down into the soil than the calcium from lime (calcium carbonate).
- This can inhibit aluminum uptake at depth and promote deeper rooting of plants.
- When roots are more abundant and can grow deeper into the soil profile, they can take up more water and nutrients, even during the drier periods of a growing season.
- Although moderately soluble, gypsum can be an excellent source of sulfur over several growing seasons.
Research found that the sulfur is available not only in the year applied, but can continue to supply sulfur for one or two years after, depending on the initial application rate. Gypsum as a sulfur fertilizer has benefitted corn, soybean, canola, and alfalfa.
Gypsum can also help improve soil structure. Many of us look at soil as a uniform, static substance. In reality, soil is a mixture of inorganic particles, organic particles, and a complex mixture of pore spaces, water, and soil microbes. Its composition changes through weather events like rainstorms, by tillage, or as plants pull nutrients for growth.
Farmers have to manage their soil well in order to maintain good crop yields year after year. Improving soil structure helps farmers with some common agricultural problems. Adding gypsum to the soil reduces erosion by increasing the ability of soil to soak up water after precipitation, thus reducing runoff.
- Gypsum application also improves soil aeration and water percolation through the soil profile.
- A recent study showed the benefit of gypsum application to improve movement of water through the profile to tile drains.
- It also reduces phosphorus movement out of the field.
- No matter what solutions farmers are trying to implement when using gypsum, they have several options for application.
Of course, the type of application method will be determined by the reasons to use gypsum. Finely crushed gypsum can be dissolved in irrigation water and applied that way. Farmers can take gypsum and apply it to the topsoil prior to planting or right after harvest.
It can also be applied to hay fields after hay cutting. If tilling is needed (again, dependent on the soil conditions), gypsum can be worked into the soil with the tilling equipment. Although gypsum has been used in agriculture for more than 250 years, the benefits it provides are still being studied.
In addition, the re-use of gypsum by-products from coal power plants reduces the need to mine gypsum from geologic deposits. It also saves landfill space. Gypsum can’t solve every agricultural problem, but it is a proven resource to add nutrients and improve soil structure.
“It’s a great example of recycling a waste product and using it in a beneficial way,” Dick says. Dick, Professor Emeritus at The Ohio State University, presented “Crop and Environmental Benefits of Gypsum as a Soil Amendment” at the November 2018 meeting of the American Society of Agronomy and the Crop Science Society of America.
The meeting abstract and recorded presentation can be found here. Research funding was obtained from a variety of federal, state, and commercial sources.
Do you add gypsum to mash or boil?
How is gypsum used for hoppy beers? – Gypsum acts to suppress harshness and astringent flavours. Gypsum is often added to hoppy beers to add a perceived dryness and enhance the hop bitterness. The sulfate ions in gypsum can enhance the perception of hop bitterness by adding a sharp, clean and almost puckering taste, while the calcium ions can help to clarify and stabilize the beer, and contribute to a dry finish.
Does gypsum raise or lower pH?
Gypsum does not change pH nor improve drainage in non-sodic situations. Gypsum is used to add calcium to soils such as serpentine with very high or toxic Mg levels.
Does gypsum alter pH?
What is Gypsum? – Gypsum is calcium sulfate dihydrate (CaSO 4 2H 2 0). Flue gas desulfurization (FGD) gypsum, such as GYPSOIL ® brand gypsum, is a co-product material derived from the scrubbing of flue gas emissions in coal-burning power plants. Gypsum can be spread with lime and litter spreaders.
Gypsum is not acid soluble and will not change the soil pH. It helps to shift the Ca and Mg levels in soil and offers a readily available form of sulfate sulfur, a valuable secondary nutrient that benefits the soil and crop. The sulfate in gypsum binds with excess Mg in the soil to form soluble Epsom salt, which moves lower into the soil profile.
This Mg is replaced by Ca, improving water holding capacity, root development and soil quality.2
Does gypsum increase or decrease pH?
Gypsum is a calcium sulfate containing product that provides both calcium and sulfate to the soil system. No change in pH can be expected from a gypsum application.
What is the rule of gypsum?
Role of Gypsum in Cement – The main purpose of adding gypsum in the cement is to slow down the hydration process of cement once it is mixed with water. The process involved in hydration of cement is that, when the water is added into cement, it starts reacting with the C3A and hardens.
- The time taken in this process is very less, which doesn’t allow time for transporting, mixing and placing.
- When gypsum is added into the cement and water is added to it, reaction with C3A particles tales place to form ettringite.
- This ettringite is initially formed as very fine-grained crystals, which form a coating on the surface of the C3A particles,These crystals are too small to bridge the gaps between the particles of cement.
The cement mix therefore remains plastic and workable. The time allowed for mixing, transporting and placing plays a important role in strength, composition and workabilty of concrete. As gypsum retards the process of hydration, it is termed as retarding agent of cement.
How long should gypsum be mixed?
3. Sprinkling – The gypsum must be quickly and evenly sprinkled into the water within 10 seconds. In accordance with EN ISO 6873, timing starts whenever the gypsum and water come into contact. After the gypsum has been soaked for 20 seconds, it can be mixed with a spatula.
How do I thicken my mash?
1. Add a Thickening Agent – This is the most common, and perhaps the simplest way, to thicken mashed potatoes. You can use what you have on hand: Flour, cornstarch, or powdered milk are all solid options that are probably already in your pantry. For what it’s worth, we —it has twice the thickening power of flour and it’s safe for gluten-free diets.
Should I use lime or gypsum?
Adding lime to soil raises the pH, which lowers the acidity. Gypsum helps correct compacted soil as well as counteracts excessive saline levels.
How quickly does gypsum work?
How long do you have to wait after adding gypsum to clayey soil before planting? General Advice • Garden Jobs Hi Helen, Gypsum is not a product that works instantly. It can take several months before you see any results. It does improve the structure of your soils by breaking up the clay particles causing the soil to become more friable. yates Answered: 8 Nov, 2011
Does gypsum increase setting time?
Discussion – Table 1 presents the average setting times of construction gypsum (APLUS ® ) and type II dental gypsum (Pro-BASE ® and SIRIUS ® ). APLUS ® gypsum has an average initial setting time of 10 minutes and 39 seconds, with a final setting time of 15 minutes and 97 seconds.
This shows that the construction gypsum (APLUS ® ) setting time meets ADA #25 standard specifications (8‒16 minutes). Pro-BASE ® gypsum has an average initial setting time of 16 minutes and 17 seconds, with a final setting time of 24 minutes and 31 seconds. These results indicate that the Pro-BASE ® gypsum setting time does not meet the ADA #25 standard.
SIRIUS ® gypsum has an average initial setting time of 24 minutes and 46 seconds and a final setting time of 33 minutes 37 seconds. The average setting time of SIRIUS ® gypsum does not meet ADA #25 standard. Other research on local gypsum products showed that the average setting time of the self-made gypsums was around 8 minutes and 7 seconds and 3 minutes and 40 seconds.14 The study above also reported an average setting time of 20 minutes and 21 seconds for dental plaster and 10 minutes and 34 seconds for dental stone.14 Table 1 shows that the average initial setting time value was lowest in APLUS ® construction gypsum and highest in SIRIUS ® gypsum.
- The final time setting values of three type gypsums in this study were different, as shown in Table 1,
- This time setting difference can be influenced by the amount of crystallization core in the gypsum.
- During the setting reaction, a nucleation process occurs between the calcium (Ca 2+ ) and sulfate (SO 4 -) ions, which form a molecular bond.
When these two molecules come together, a nucleus of crystallization will emerge. The higher the number of crystallization nuclei, the faster the formation of dihydrated crystals so that gypsum will harden faster.10 The factor making the average setting time of type II dental gypsum longer in this study than the ADA #25 standard (8‒16 minutes) is the hygroscopic nature of gypsum material (drawing water from the air).
Gypsum storage contaminated with air can attract water and cause low solubility of dihydrate molecules, increasing the setting time of gypsum. Based on ISO 6873, the standard for Dental gypsum storage is 50% ± 10%.15 Other research on gypsum material found that Indonesia’s humidity level is quite high, reaching 70%.16 The annual weather report (2019) showed that in Jakarta (the capital of Indonesia) January is on average the most humid; September is the least humid month; and the average annual humidity percentage is 80.0%.17 High humidity can affect the properties and reduce the quality of gypsum material.16 Gypsum with hygroscopic properties will become moist (damp) in places with high humidity.18 The water content in gypsum powder reduces the gypsum hemihydrate molecule, increasing the setting time of the material.11 SIRIUS ® gypsum’s setting time was the highest compared to the other two gypsum products.
A factor that increases the setting time of SIRIUS ® gypsum is the powder-to-water ratio when gypsum is manipulated. This study used a powder-to-water ratio of 2:1 following the Type II dental gypsum ratio. SIRIUS ® gypsum manufacturer recommends a 3:1 powder-to-water ratio, which is a type III gypsum ratio.10 SIRIUS® gypsum is thought to be an Orthodontic plaster containing type II gypsum and type III gypsum.19 Α-hemihydrate particles are low in porosity so that they do not require as much gypsum as water compared to β-hemihydrate particles.20 The excess water used when mixing would make the gypsum’s setting time longer.18 This gypsum material contains α-hemihydrate particles with a denser and less porous particle structure so that it can be used for manufacturing study models because it re-produces accurate oral anatomy.21 The long setting time for SIRIUS ® gypsum is because the orthodontic gypsum’s working time is longer than other gypsums, aiming to achieve more accurate study models.10 Another factor influencing the difference in gypsum setting time in this study is composition.
- The three tested gypsums have different manufacturers, with different percentages of calcium sulfate hemihydrate and other chemicals in their structure.
- Several chemicals are used by manufacturers to manipulate the setting time for a gypsum product.
- A material often used to prolong the setting time is 1‒2% borax.
Borax can form a coating on a hemihydrate molecule so that it cannot contact water, decreasing the solubility of the hemihydrate (i.e., increasing the setting time). The material often used to speed up setting time is 2‒3% potassium sulfate. These chemicals can make hemihydrate molecules more soluble when mixed with water.2, 10, 22 This study showed the lowest initial setting time and final setting time in APLUS ® construction gypsum, while the highest initial setting time and final setting time were recorded in SIRIUS ® type II dental gypsum.
Does gypsum taste salty?
ROCK GYPSUM Rock gypsum (a.k.a. gyprock) is a chemical sedimentary rock. It is an example of an evaporite – it forms by the evaporation of water (usually seawater) and the precipitation of dissolved minerals. Rock salt & rock gypsum often occur together in evaporitic successions.
Rock gypsum is composed of the mineral gypsum (CaSO 4 2H 2 O – hydrous calcium sulfate). Heating of gypsum or rock gypsum drives off the water, leaving only calcium sulfate behind (the mineral anhydrite ). Adding water to anhydrite results in the formation of gypsum again. Rock gypsum, unlike rock salt, does not have a salty taste, and is softer (H = 2) – it can be scratched with a fingernail.
Rock gypsums color is often a mottled whitish-light grayish-light brownish. It is usually microcrystalline and powdery looking (it’s much finer-grained than typical rock salt deposits). Rock gypsum superficially resembles chalk. Chalk is calcitic, and so will bubble in acid – rock gypsum does not bubble in acid. Rock gypsum (Gyprock) Home page
What is the pH of gypsum?
Gypsum – Gypsum, or calcium sulfate (CaSO4), is a naturally occurring mineral. It provides calcium & sulfur, both essential nutrients, but does not affect soil pH. Gypsum is a neutral salt (pH is ~6.7) and has a salt index, or osmotic potential, of 8. It typically has 20 to 22% calcium, and 16 to 18% sulfur. The sulfur is in a plant available, or sulfate (SO4) form. In addition to providing needed nutrients, the calcium in gypsum is soluble, even at a pH that is >7. This can be very helpful in improving soil tilth, reducing soil compaction, lowering sodium and improving aeration. Gypsum is not the only way plants can get sulfur, but the sulfates in gypsum will not raise soil’s pH levels like elemental sulfur, the other commonly used additive. Elemental sulfur also has to steal calcium and oxygen from the soil in order to make its sulfur usable, something gypsum does not do.
Does gypsum change soil pH?
Gypsum is NOT lime. –
In order to adjust soil pH, liming products must contain carbonate (CO3-) which reacts with hydrogen ions to neutralize soil acidity. Gypsum is calcium sulfate (CaSO4). While the calcium will displace hydrogen ions, these ions will remain in solution and will not adjust soil pH.
Why do you add gypsum to wort?
Calcium Sulphate (Gypsum) is an important mineral for its effect on mash and wort pH. Used to harden water when brewing ales and bitters. Use as required depending on water hardness. Gypsum (Calcium Sulphate) adds permanent hardness (calcium ions) to brewing water; 1 gram per US gallon adds 62 ppm calcium, 147 ppm sulfate.
Calcium Sulphate (Gypsum) is used to “harden” the process water or as a direct additive to the malt mash or kettle wort. The benefit comes from the Calcium ion. More on Calcium Sulphate or Gypsum: Calcium Sulphate is a critical component in the measurement of permanent water hardness (also known as non-carbonate hardness).
This part of water hardness is defined by the sum of all calcium and magnesium ions that are associated with anions such as chloride or sulfate. It is referred to as permanent hardness because of the fact that it will not precipitate under the influence of heat.
- Therefore, calcium sulfate is also one of the primary salts used for the improvement of calcium levels in beer.
- Proper calcium levels in beer can provide the following influences that are generally considered to be positive: they lower the pH, preserve mash enzymes, increase extract yield, improve yeast growth and flocculation, accelerate oxalate removal, and reduce color.
The sulfate ion in this compound is generally thought to promote a drier, more bitter beer. Burton-on-Trent, England is the classic source of water with a high calcium sulfate content, caused by the region’s large gypsum deposits. The emulation of this classic water has led to the term “Burtonization,” meaning to improve one’s brewing water via the addition of calcium sulfate.
What does gypsum do to water pH?
Gypsum Can Be Used for Safe Water Clarification of a Muddy Pond or Lake Water – Gypsum (CaSO4) is a water soluble mineral that can be found in fertilizers and mixed in many other products. It is pH neutral, therefore, its application does not have the risk associated with alum treatments.
