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.

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

    • 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

    • @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

    • Hello y’all
      I’ve been making moonshine for abot three years straight. My biggest feat was not making enough out of one batch. I bought a 3 gal batch still out of eBay. I have a 55 gal plastic drum that I filled with 20 gal of mash. For the 5 gal mashes I had in the past I used I pachet of fleshmans yeast and weilded great results I’m now making 20 gallons of the same mash but will use 4 packets in stead of one. It does great and I’ve the tried turbo yeast. The secret is raisons and I added corn starch as well. It gives the yeast something to eat off of instead of just the sugar. Which keeps it alive longer which gives u more alcohol. It’s so cheap and easy after a few days I just add more yeast just to make sure. I’ve gotten great results and do not see a need for turbo yeast. Yeah the avb is a little higher but for the price and waiting it, to me, isn’t worth it. I got 5 percent with bread and 8 for turbo but turbo was way expensive and I had to order it. Yeast gets 4 and a half in my book and I suggest it to anyone making shine or whisky.

    • If you use turbo yeast and keep a bit of tails to grow you own, would this be the best of all worlds?

    • I am an old shiner, I have been doing this since I was 8, when my pap paid me a dollar a day to clean the mash barrels and haul the wood for his fire. I started my own still when I was 14, with paps help of course. He always used the natural yeast from the grain when he malted it, except when the weather got colder then he would use grams bread yeast to help it out. We didn’t have a lot of money so that’s what we had to use. His whiskey was famous in the hills of WV and he never had a problem getting rid of it. I retired his still 30 years ago but still run an 85 gallon still with a 5 gallon thump. My son started shining when he was in his 20s after college, he said to keep the tradition alive, but he started getting information off the internets to improve the quality. After much trying and tasting, he is now running his still with bread yeast. The taste is cleaner and fresher and the proof is as good as ever. Does bread yeast work? Yep you can bet your socks on it, works every time.
      I am very happy that there are so many of yall learning to make your own whiskey. Just remember the cleaner the ingredients the better the taste. Happy shining

    • Mountain Mike:
      No….they/I/We are not kidding. Bread yeast is the best, simplest, cheapest answer there is. Bread yeast is more or less a blank slate in a technical level, it hasn’t “learned” or “inherited” any of the traits of its predecessors.
      These “inherited” traits are what the massive breweries/ distilleries rely upon to maintain a constant production quality and/or flavor in the final product. As a matter of fact, the Guinness brewery has used the same strain of yeast for hundreds upon hundreds of years, and are a VERY highly guarded secret. They literally keep their yeast in a temperature controlled vault.
      You can reproduce the flavor of your own product by keeping the “tails” of one batch to add to the next. The yeast will “learn” and become a clone of the last batch. After a few progressive turns like this (approximately 7 or so), your final product will be as reliable as a professional distillery.

    • help
      I am new to making whiskey and am having a problem, I have tried three different yeasts the last one I tried was Fleischmann’s as you suggest, all have worked for 36 hours and them died off leaving little or no alcohol content in the mash. Any help will be appreciated.

      Posted by Jim on December 08, 2014
    • Hunter, sounds to me that is just the krausen from the yeast. Nothing wrong all top fermenting yeast will do that. If a secondary “skin” or anything floating after initial krausen I would be worried then.. The gunk on your carvery should wash fine with a mild soap which can be found for brewing in homebrew shops.. Happy brewing!

    • Bread Yeast works great but I have never had an ABV of more than 10%. I always end up with about a solid gallon of 80 to 90 proof moonshine on a 5 to 6 gallon mash.

      Posted by Barper on August 07, 2014
    • I gave the bread yeast a try by mixing with water and sugar for the first time. After a few hours the yeast formed like a cake on top of the mash and finally went away and now there’s stuff caked on the side of my Carboy. My airlock was bubbling like crazy for 2 days and it is now day 4 and barley bubbling. What could be wrong?
