The Best Yeast for Distilling and Brewing
Distillers and Brewers Yeast Review
We get a lot of questions about yeast. Folks want to know "which yeasts are the all-time" for fermenting a brew.
These days, homebrew shops offer an incredibly robust selection of yeasts. However, non everyone has easy access to a homebrew shop, and ordering yeast online can be dicey because temperature fluctuations may cause harm. Therefore, this article focuses on very basic yeasts which anybody should accept admission to, plus a few more than that are temp tolerant. We've tested a total of four yeasts and the results are below.
Before we get started, a reminder: Distilling alcohol is illegal without a federal fuel alcohol or distilled spirit plant permit likewise as relevant state permits. Our distillation equipment is designed for legal uses only and the information in this article is for educational purposes only. Delight read our complete legal summary for more data on the legalities of distillation.
To make things easy, we fabricated a 2 gallon mash using three pounds of pure cane sugar and ii pints of unsulfured molasses (with a potential booze of 12.9%). Nosotros so split the brew into 4 glass carboy's and added a different yeast to each container.
One of the following yeast strains was pitched in each of the carboys:
- bread yeast
- champagne yeast
- super starting time distillers yeast
- turbo yeast
We let the batches ferment for nigh 3 weeks (to make sure nosotros had maxed out the potential of each yeast), then nosotros conducted a taste test. We didn't carbonate or distill or otherwise alter the fermented liquids. We only gustation tested as is. First, these wouldn't brand for very good beers. Second, we could take distilled them, every bit this is more than or less a rum brew recipe, but nosotros simply have a fuel booze permit, so we couldn't accept drank the final product anyhow. Call back, distilling booze at home for consumption is illegal. Don't do it.
Our assumption was that the bread yeast had non met its booze potential and would be sweeter than the remainder of the samples due to excess sugar. We as well assumed that the turbo yeast might taste and smell a fleck funky, considering that's what a lot of people report nigh information technology. We also have some experience with turbo'southward ourselves and take noted these characteristics. We thought the champagne yeast would exist dry out, and weren't sure how the super start would taste amid the rest of the samples. We hadn't taken a final specific gravity reading before the taste exam, and so the alcohol content of the samples was not known to u.s. every bit we were sampling them.
Every bit it turns out, our assumptions were dead on, with 1 surprising exception. Hither'southward what we noted:
Turbo Yeast
We tested Liquor Quick's Turbo Pure X-Press (dehydrated), which is rated to produce up to 18% alcohol. According to the manufacturer, this yeast was created to produce "a very clean wash with minimal congeners." Nosotros disagree with the kickoff function of that statement.
The launder was anything but clean. Information technology smelled and tasted absolutely awful, most likely due to excess nutrients that weren't used by the yeast. In defence of Liquor Quick, maybe if we had added more than sugar and the yeast were able to work longer (using more than of the nutrients) the launder would not take tasted so bad.
We actually agree with the 2d part of theto a higher place mentioned statement. The launder independent very few congeners. Congeners is a fancy term for all of the tasty ingredients institute in the mash. The more congeners, the more brew flavor, the less congeners, the more devoid of gustation the wash and final product will have. There was hardly any trace of the cane and molasses flavors. However,remnants of the nutrients were nonetheless very nowadays and the wash tasted and smelled terrible.
In summary, we only recommend turbo yeast for making fuel for lawnmowers.
Champagne Yeast
We tested Ruddy Star's Pasteur Champagne Yeast (dehydrated). The champagne wash sample was extremely dry. Molasses and cane flavors from the wash were about completely gone. A very slight bitter taste from the molasses was all that remained, which is definitely non the all-time part of the molasses flavor. The yeast itself likewise imparted picayune to no flavour to the wash, making this sample extremely make clean. If a commercial distiller is striving to make aneutral grain spirit, such as vodka, we think champagne yeast would work very well. However, it is now credible to us that a commercial distiller would probably not apply this yeast for flavorful spirits such as corn whiskey, full bodied, accurate rums, etc..
Super Offset Distillers Yeast
We tested Crosby & Bakery's Super First Distillers Yeast, at present known but every bit Distillers Yeast (UPC: CB 9904A*). This stuff is available past the pound and is given no description past the maker. Over the years this is the yeast nosotros've become accustomed to using, partly considering it's sold by the pound (and It takes a long time to use an unabridged pound of yeast) and partly considering we experienced what we felt were good results. Our assumption was that this yeast was going to blow the competition away. Even so, we were incorrect.
The Super Start wash tasted almost exactly like the champagne yeast launder. They were actually a bit difficult to tell autonomously. The only difference was that the champagne yeast had a slightly cleaner gustation and smell. Yeasty smells and flavors were a bit more prevalent in the SS sample. In our stance, considering these samples didn't taste annihilation like cane or molasses, these yeasts are probably better suited for commercial distillers making high alcohol, neutral grain spirits than they are for making sippin' whiskeys. Because the champagne yeast had a cleaner gustation than the Super Start, we'd venture to say that it'd exist the better selection betwixt the two.
Accordingly, due to the results of this experiment, we at present no longer exclusively recommend Super Kickoff equally our yeast of choice.
Staff of life Yeast
The surprise of the solar day was bread yest. We tested Fleischmann'due south Agile Dry out Yeast. Our initial assumption was correct: the bread yeast tasted slightly sweeter than the others. Much more of the cane sugar and molasses flavors were present. Overall, this was actually the all-time tasting launder, which nosotros kind of half expected. We assumed that the bread yeast sample tasted amend considering the yeast had hardly washed anything and hadn't produced much booze. However, we were dead wrong.
The ABV of this sample was on par with the rest of the samples (see below). This ways that breadstuff yeast had managed to produce equally much alcohol as the rest of the yeasts, simply had done and then without stripping out as much of the natural mash flavors. This wash tasted bang-up and nosotros see no reason to recommend confronting using bread yeast.
Alcohol Yield
We determined potential alcohol using a beer hydrometer. We also did some calculations by hand to back up hydrometer readings (and to show how smart we are). Likewise, our brix refractometer was missing on test solar day, which is the other reason for the hand calculations.
Our beer hydrometer displayed a starting gravity of 1.10, corresponding to a potential booze of 13%. Betwixt the molasses and the pikestaff sugar, we ended up adding a full of 969 grams of sugar to a total of 3785 grams of water, for a brix of 25.half-dozen and a potential booze of 12.8%. Because the effect of both calculations is and so shut nosotros're very confident that the potential booze was somewhere around 12.9%.
The final gravity measurements of wash samples were almost identical. The samples were all inside a half pct of 12.5% starting alcohol, with champagne being slightly college than the rest. In other words, each yeast substantially maxed out its alcohol production potential by eating more or less all of the sugar present in the wash.
These results convey absolutely nothing meaningful about the booze production potential of champagne, turbo yeast, and Super Outset yeast. It'due south obvious that these yeasts should be able to produce 12.5% ABV or higher. If nosotros wanted to compare the alcohol yield potential of these yeasts we'd need to bump up the carbohydrate content of the launder and give the yeast samples more to work with.
However, the experiment sheds some interesting lite on the alcohol production potential of bread yest. We assumed that bread yeast would accept stalled out well before consuming all of the sugar in the mash. Nosotros can now say with confidence that bread yeast (at least the brand we used) is able to produce 12.5% starting ABV, and maybe even higher. This is surprising news to united states of america, as our previous (limited) experience with bread yeast suggested a much lower potential ABV.
Additional Yeast Resources
For those that accept not read our article "Making Moonshine - Fermentation and Yeast" bank check that out as nosotros get into more detail about the fermentation procedure. It'southward for educational purposes only, only is very interesting. We strongly suggest purchasing a re-create of the book "Yeast" from Amazon.com. This books is 300 pages long and was written past professional person brewers and scientists. Information technology'due south an awesome resources on the topic of yeast. We've been reading this volume and accept learned a ton of stuff about yeast. Yeast is just as important as the other ingredients (corn, barley, sugar) in beer and fine spirits, and without yeast, the world as nosotros know it would probable be devoid of alcohol.
Get this volume to learn how a commercial distiller would improve the quality of their whiskey.Also, checkout our article " Bourbon, Whiskey, Vodka and Moonshine - How Much Yeast?" for more information on how much yeast to employ on a batch of mash.
