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. If you have read The Best Yeasts for Distilling you know that 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 you add to your mash.

Champagne or Beer Yeast

Whiskey mash with Bread Yeast If you are 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. If you are using champagne/beer yeast use 1 packet for every 5 gallons of mash.

Distillers Yeast

If you are 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

If you are using bread yeast we have had great results with Fleischmann's bread yeast over the years. You can buy bread yeast 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 increasefor the convenience/storage factor. If you follow the steps we have outlined below you will have great results using bread yeast as well.

    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 you are 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 your starter has doubled in size add it to your mash and aerate.

    • 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.

    • ok so i am not really new at this as we have been making shine now for awhile but this week we have had a few issues. We ran out of Daddy yeast and we had some turbo. We went ahead a used a whole package of turbo yeast for a 5 gallon bucket of sugar mash. I used 5 lbs of sugar in the bucket. The bubbler went crazy the first 2 days and now it is stopped. I read somewhere this morning that you should not use Turbo yeast in shine so i decided to make a different batch (I have not dumped the bucket out yet), Question, is this still ok and is it true you should not use Turbo?
      I went ahead and decide to make another batch in another 5 gallon bucket. I dont have any yeast so i went to the grocery store and got bread yeast. It says to use 2 packets so that is what i did. Again i have a 5 gallon bucket, 5 lbs of sugar and 2 packets. I I started the yeast in a half cup of 110 degree water and 2 tsp of sugar until it doubled and dumped it in the bucket with my new bucket of sugar mash mixture. It has not started to bubble. What did i do wrong? I have 2 buckets of sugar water with yeast. What do i do??? Please please help me

    • Hi Emmet

      I still haven’t seen in the blogs how much yeast to use ? The best i can see or work out is 10 grams per litre of mash. I was using turbo but have just started my first one with bread yeast . I will let you know how it goes.

      Cheers Shane

    • how much bread yeast tomato paste and how much lemon for 5 gallons

      Posted by glen on April 26, 2016
    • Hi, Paul,
      your best bet is to check with your hydrometer as I have found that if your mash is only bubbling every 30 secs. or so then your mash is probably ready or as ready as its going to be. because of your low temp.You could try putting your mash somewhere warmer for a couple of days,see if you get any response, if not rack it

      Posted by james on April 14, 2016
    • @Paul, Hi there i saw your question regarding the fermentation of your wodka mash. i would recommend to just let it sit till basically no more bubbles come. it is quite odd in my opinion that after 36 days still bubbles come but that is not bad or anything. do not add any extra yeast because for as far as i know that will not work well. best is just to wait. how much yeast did you add in the first place ?

      Kind regards,

      sam
