Bourbon, Whiskey, Vodka and Moonshine - How Much Yeast?

We get a lot of questions about yeast. Everyone seems to want to know how much yeast is needed for making 5 or 10 gallons of mash. For those that have read The Best Yeasts for Distilling, it's obvious we are very fond of bread yeast. We have found over the years that bread yeast can easily produce as much alcohol as other yeasts if used correctly.

The question we hear a lot is "How much yeast do I need for the ____ recipe?" The answer is "It Depends." Every type of yeast is slightly different. In general, yeast can be categorized into three different groups: champagne & beer yeast, distillers yeast, and bread yeast. Use the following guidelines for measuring the quantity of yeast that is added to a mash.

Before we get started, a reminder: Distilling alcohol is illegal without a federal fuel alcohol or distilled spirit plant permit as well as relevant state permits. Our distillation equipment is designed for legal uses only and the information in this article is for educational purposes only. Please read our complete legal summary for more information on the legalities of distillation.
 

Champagne or Beer Yeast

Whiskey mash with Bread Yeast When using a champagne or beer yeast it will have directions on the packet. Every champagnebeer yeast we have ever used is packaged to ferment 5 gallons of beer. When using champagne/beer yeast use 1 packet for every 5 gallons of mash.

Distillers Yeast

When using distillers yeast follow the directions on the packet.  If there are no directions we suggest 1 tablespoon of yeast per 5 gallons of mash.

Bread Yeast

When using bread yeast we have had great results with Fleischmann's bread yeast over the years. Bread yeast can be bought in packet form or in 1-2 pound bulk packages. It is normally cheaper to buy in bulk but it is more convenient to store the yeast in packets. We prefer packets and can justify the slight cost increase for the convenience/storage factor. Just follow the steps we have outlined below in order have great results using bread yeast.

    Create a simple yeast starter for 5 gallons of mash

    1. Add 1/2 cup of 110 degree water to a sanitized jar.
    2. Add 2 teaspoons of sugar to the water and mix thoroughly.
    3. Add 2 packets of yeast (14 grams or 1 tablespoon if using bulk yeast).
    4. Swirl the glass to mix in the yeast with the sugar water.
    5. Let the glass sit for 20 minutes and it will double in size.
    6. Once the starter has doubled in size add it to the mash and aerate.

    Remember, it is illegal to distill alcohol at home for consumption. Do not do this.

    • (((Does yeast have anything to do with Fighting liquor vs courtin/lovin liquor?
      What is the difference in the process/recipe?
      How do You insure Your going to make courtin/lovin liquor and not fighting liquor?)))

      Answer—-You must be kidding, Right? —Do Yourself a huge favor and stop at your local store, and buy yourself a bottle of "crown royal apple. This is excellent courtin Liquor, and it contains less that .15 fights to the pint. If your question was serious,,,, please do not attempt to distill anything flammable, ever.

    • At what temp should I add yeast to corn mash distillers act dry yeast

      Posted by RIck on April 15, 2019
    • A week ago made 2 batches 6gal each of corn mash using ~8lbs corn, 1lbs of malted rye, 1lbs of malted barley and 8lbs sugar in each batch. Used 48hour turbo yeast and bubble like crazy for 2 days and has been bubbling a little still, 5 days later. Yesterday I made another 2 batches and they bubbled like crazy for only 1 day and have since stopped. Should I try adding more yeast? I now have some Distillers active dry Yeast should I hydrate some and add?

    • In my 15 gal.mashes, I use 20 lb. sugar,7 teaspoons of bread yeast.you will also need some yeast nutrient,box of raisins or believe it or not small tomato paste. Most importantly airate well with mixer. Wii form a nice cap,and start a rapid ferment in hours. Most mashes all grain for whiskey,Rye and corn Vodka.
