Most people buy the wrong yeast out of the Distiller's Range because the four options look interchangeable on the shelf. They are not. One of them is a different species to the other three, two of them tolerate 18% ABV while two stop at 15%, and one will still finish a wash in a cold garage in July when the others have gone to sleep. The Distiller's Range works for craft distilling when you match the yeast, the nutrient dose and the enzyme sequence to the base you are fermenting, and the specs that tell you how to do that are buried on eight separate product pages.
Key Takeaways
- The Distiller's Range is four yeasts (Whiskey, Rum, Vodka, Gin), two nutrient blends (Dark Spirits, Light Spirits) and two enzymes (high temperature alpha-amylase, glucoamylase). Each pack treats up to 25 litres.
- Gin Distiller's Yeast is the only strain in the range classified as Saccharomyces bayanus rather than Saccharomyces cerevisiae, and the only one rated down to 12°C. Every other yeast in the range needs 20°C or above.
- Vodka and Gin Distiller's Yeast both tolerate 18% ABV. Whiskey and Rum stop at 15%.
- Distiller's Nutrient Light Spirits is dosed at 150 g per 25 litre sugar wash. Dark Spirits is dosed at 75 g for the same wash, exactly half, despite carrying higher total nitrogen (at least 10% versus at least 6%).
- Neither nutrient has a dose for an all-grain or malt extract mash. Grain supplies its own nitrogen, so on a true grain bill you skip the nutrient entirely.
What the Distiller's Range actually is
The Distiller's Range is Still Spirits' strain-specific fermentation line: four single-strain distiller's yeasts, two nutrient blends split by spirit colour, and two enzymes for starch conversion. Each yeast sachet is 20 g and treats up to 25 litres. Each enzyme sachet is 12 g. Each nutrient tub is 450 g. The whole range sits in the specialty yeast, nutrients and enzymes collection.
The word that explains the range is congener. A congener is any compound produced during fermentation other than ethanol and water: esters, higher alcohols, aldehydes, acids. Congeners are what make a whiskey taste like whiskey rather than like neutral spirit with colouring in it.
That is the split between the Distiller's Range and ordinary turbo yeast. Turbo yeast is bred for speed and high alcohol tolerance on a sugar wash, and the congeners it throws are treated as a problem to be stripped out later with carbon. Distiller's yeast is the opposite bet: you pick a strain for the congeners it produces, then you use a still that keeps them.
That is also why the Distiller's Range is the wrong purchase if you are making vodka from a sugar wash and carbon filtering it afterwards. You will not taste the difference. It earns its money on grain, molasses and fruit, where the yeast character survives into the glass.
The four Distiller's yeasts compared
All four Distiller's yeasts come in 20 g sachets sufficient for 25 litres, with more than 1 x 10^10 viable cells per gram and a 24 month shelf life. What differs is species, alcohol tolerance, attenuation, flocculation and the usable temperature band. Those five figures decide which one will actually finish your wash, and they vary more than the product names suggest.
| Yeast | Species | Alcohol tolerance | Attenuation | Flocculation | Temperature range |
|---|---|---|---|---|---|
| Whiskey | S. cerevisiae | 15% ABV | 90 to 100%, high | Medium | 20 to 35°C |
| Rum | S. cerevisiae | 15% ABV | 70 to 100%, low to high | Medium | 20 to 34°C |
| Vodka | S. cerevisiae | 18% ABV | 80 to 100%, high | Low | 20 to 32°C |
| Gin | S. bayanus | 18% ABV | 70 to 100%, low to high | Low | 12 to 32°C |
Three things fall out of that table that are worth more than the marketing copy.
Gin Distiller's Yeast is the odd one out, and it is the useful one in winter. It is the only strain in the range classified as Saccharomyces bayanus, and its rated floor is 12°C against 20°C for everything else. S. bayanus var. uvarum is a recognised cryotolerant species, better adapted to low temperature fermentation than S. cerevisiae, and a PLOS One study comparing the two at 12°C identified the metabolic differences behind that adaptation. Practically: if your ferment lives in an unheated shed in Melbourne or Hobart and the overnight temperature drops into the low teens, Gin Distiller's Yeast is the only strain in this range rated to keep working. The other three will stall and you will blame the yeast when the problem was the shed.
Low flocculation is not a fault here. Vodka and Gin Distiller's Yeast both flocculate low, which means the yeast stays in suspension rather than dropping to the bottom. For a beer that would be a nuisance. For a wash you are about to distil, it means you should plan on either a clarifier or a settling period before you siphon, because siphoning cloudy wash pulls yeast into the boiler.
Attenuation ranges are not promises. Whiskey and Vodka are rated high (90 to 100% and 80 to 100%). Rum and Gin are rated 70 to 100%, which is a way of saying the finish depends heavily on your base and your temperature. On a molasses wash, a Rum yeast landing at 70% attenuation is a normal outcome, not a failure.
Which Distiller's Nutrient, and how much
Distiller's Nutrient comes in two versions and the choice follows the spirit, not the base. Dark Spirits is formulated to enhance congener production for whiskey, brandy and dark rum. Light Spirits is formulated to reduce off-flavour production for vodka, gin and white rum. Both tubs are 450 g and both are dosed per 25 litre batch, but the dose rates differ by a factor of two.
| Base | Dark Spirits dose per 25 L | Light Spirits dose per 25 L |
|---|---|---|
| Sugar wash | 75 g (up to 15%) | 150 g (up to 15%) |
| Fruit mash | 50 g (up to 15%) | 100 g (up to 10%) |
| Molasses wash | 50 g (up to 12%) | 100 g (up to 12%) |
| Malt extract or grain mash | Not dosed | Not dosed |
| Total nitrogen | At least 10% | At least 6% |
The doubled dose is the part that catches people out. Light Spirits needs 150 g on a sugar wash where Dark Spirits needs 75 g, even though Light Spirits carries the lower nitrogen figure. A 450 g tub of Light Spirits is therefore three sugar-wash batches, while the same size tub of Dark Spirits is six. If you are budgeting consumables for a season of vodka, buy accordingly.
The "not dosed" row matters just as much. Neither nutrient has a published rate for an all-grain or malt extract mash, because grain already supplies the nitrogen and the trace minerals the yeast needs. On a genuine grain bill, adding nutrient is money spent on nothing. That is the one place in this range where the honest answer is to leave a product in the shop.
Both nutrients are also irritants in powder form. The labels carry warnings for skin, eye and respiratory irritation, so measure them without a fan running and wash your hands afterwards. Worth saying because most people treat yeast nutrient as flour.
The two Distiller's enzymes, and the order they go in
Enzymes only enter the picture when your base is starch: grain, maize or potato. There are two of them and they run in sequence, not in parallel. High temperature alpha-amylase goes in first at 65 to 80°C to liquefy gelatinised starch into short chain dextrins. Glucoamylase goes in second, once the mash is below 65°C, to break those dextrins into fermentable simple sugars.
| Property | Alpha-amylase (high temperature) | Glucoamylase |
|---|---|---|
| Source | Bacterial | Fungal |
| Job | Liquefaction: starch to dextrins | Saccharification: dextrins to simple sugars |
| Add at | 80°C or just below, hold 65 to 80°C | Below 65°C, optimum 50 to 60°C |
| Hold time | 60 minutes | 60 minutes |
| pH window | Standard mash | 2.8 to 5.0, optimum 4.0 to 4.5 |
| Treats | Up to 7.5 kg starch per 25 L | Up to 10 kg starch per 25 L |
| Pack size | 12 g | 12 g |
Order is the thing the old version of this page got wrong, and it is worth being blunt about it. Listing glucoamylase before alpha-amylase, as the previous edit of this article did, inverts the process. Alpha-amylase cannot do its job once the mash has cooled below its window, and glucoamylase added to unliquefied starch has very little to work on. The commercial sequence is the same one: liquefy hot with alpha-amylase, cool, then saccharify with glucoamylase. Distiller Magazine's primer on mash chemistry walks the same order for grain spirits production.
Two details that trip people up:
The pH optimum is not the mashing pH you may have read. Malted grain mashing with the grain's own diastatic enzymes runs around pH 5.2 to 5.8. Still Spirits glucoamylase has an optimum of pH 4.0 to 4.5 and stops working above pH 5.0. If you are following a homebrew mash schedule and adding glucoamylase to it, you are likely adding it into a pH where it barely functions.
You can skip the separate saccharification rest. Glucoamylase can be added along with the yeast and nutrient and left to work during fermentation at 30 to 35°C, which is simultaneous saccharification and fermentation. It is slower but it removes a temperature-holding step, which matters if you do not have a mash tun that holds heat.
Alpha-amylase is genuinely optional on a boiled, well-mashed potato or grain wash: glucoamylase alone will convert some of it. What you lose is yield, because liquefaction was incomplete. Skipping it is a defensible choice, but it is a yield decision, not a step you can move later in the process.
Yeast, nutrient and enzyme by spirit type
The combination you want depends on the base as much as the spirit. Below is every combination the current Distiller's Range supports, with the 25 litre nutrient dose and the still that suits the result. This replaces the chart image that used to sit at the bottom of this page, which search engines and screen readers could not read.
| Spirit | Base | Yeast | Nutrient per 25 L | Enzymes | Still |
|---|---|---|---|---|---|
| Whiskey | Grain mash | Whiskey | None, grain supplies nitrogen | Alpha-amylase then glucoamylase | Alembic pot still |
| Whiskey | Sugar or malt extract | Whiskey | Dark Spirits 75 g on sugar | None | Alembic pot still |
| Bourbon | Maize mash | Whiskey | None, grain supplies nitrogen | Alpha-amylase then glucoamylase | Alembic pot still |
| Dark rum | Molasses or treacle | Rum | Dark Spirits 50 g | None | Alembic pot still |
| White rum | Sugar or molasses | Rum | Light Spirits 150 g sugar, 100 g molasses | None | Alembic pot still |
| Vodka | Potato | Vodka | Light Spirits 100 g | Alpha-amylase then glucoamylase | T500 reflux |
| Vodka | Sugar wash | Vodka | Light Spirits 150 g | None | T500 reflux |
| Gin | Sugar, potato or grain | Gin | Light Spirits 150 g sugar, 100 g mash | Only if starch based | T500 reflux, then botanicals |
White rum is the row worth a second look. It takes the Light Spirits nutrient, because you want the off-flavours suppressed, but it still goes through a pot still rather than a reflux column, because stripping every congener out leaves you with vodka. Light nutrient, heavy still. That combination is not obvious from the product names.
What the range does not cover
There is no dedicated Distiller's yeast for brandy, tequila or agave spirits. Distiller's Nutrient Dark Spirits does publish a fruit mash dose of 50 g per 25 litres and names brandy in its application notes, so the nutrient side is covered. The yeast side is not, and this page is not going to pretend otherwise. For fruit spirits you are choosing a strain from outside this range.
Which still suits which spirit
Dark spirits want a pot still, light spirits want a reflux column. The Alembic pot still carries congeners through into the distillate, which is the whole point of using a Whiskey or Rum Distiller's Yeast. The T500 reflux still strips them, which is what you want behind Vodka or Gin Distiller's Yeast.
If you own a T500 and not an Alembic, there is a workaround in the Still Spirits product notes that almost nobody mentions: run the T500 condenser with the ceramic saddles removed. Pulling the packing out of the column kills most of the reflux action and gives you something closer to a pot still. The result has less character than a proper Alembic dome and condenser, and Still Spirits says so plainly, but it is a real option before you spend money on a second condenser.
The reverse does not work as well. Running a pot still for vodka means triple distillation for a poorer result and a much lower yield. If light spirits are the goal, the reflux column is not a nice-to-have.
For gin specifically, the yeast and the still get you neutral spirit and the character comes afterwards, from the gin botanicals and profiling range.
A worked 25 litre potato vodka wash
Twenty kilos of potatoes, 20 g of Vodka Distiller's Yeast, 100 g of Light Spirits nutrient, 12 g of glucoamylase and optionally 12 g of alpha-amylase gets you a 25 litre wash at 9 to 10% ABV. You can halve the potatoes to 10 kg and make up the difference with 2.5 kg of granulated sugar. The full method is on the Vodka Distiller's Yeast page, and the short version is:
- Scrub the potatoes, dice them without peeling, and boil in just enough water to cover until they mash easily, roughly 15 minutes.
- Drain, mash smooth, then add water and stir to a liquid consistency at less than your final fermentation volume. Return to the heat.
- As the slurry approaches the boil, stir in the alpha-amylase. Simmer 30 minutes, stirring so it does not catch.
- Kill the heat, cover, and stand one hour while the starch liquefies. Check the temperature every 10 minutes with a sanitised thermometer. The slurry is exposed to contamination at this stage, so anything that touches it gets sanitised first.
- Once below 65°C, stir in the glucoamylase and stand another 60 minutes. Or cool to 30 to 32°C and add it with the yeast for simultaneous saccharification and fermentation.
- Transfer to a 30 litre fermenter, add sugar if you are using it, and top up to 25 litres at 20 to 32°C. The extra 5 litres of headspace is for the foam.
- Add the yeast and 100 g of shaken Light Spirits nutrient together, fit the lid and airlock, and ferment at 20 to 32°C.
- Stir the solids cap back in once or twice a day for the first few days. Fermentation should finish inside 7 days at 20°C or above.
- Strain through a sieve or cheesecloth, then stand 1 to 2 days to settle. Turbo Clear speeds this up.
- Siphon off the sediment into the still and run it. Carbon filter afterwards if you want a cleaner vodka.
A note on the legal position, since this is Australia: distilling spirits requires an excise manufacturer licence from the ATO regardless of still size or what the spirit is for, and the ATO's page on unlicensed manufacture sets out what that means. We cover it in full in our guide to whether it is illegal to distil alcohol in Australia.
Frequently asked questions
Can I use Distiller's yeast in place of turbo yeast? Yes, but not for the same job. Turbo yeast is built for a fast, high-alcohol sugar wash that gets carbon filtered afterwards. Distiller's yeast produces a specific congener profile you are meant to keep, and it tops out at 15 to 18% ABV rather than the 20% plus a turbo yeast will reach. Swapping one in for the other on a sugar wash destined for carbon filtering gains you nothing.
Do I need both enzymes? Only if you are fermenting starch, and even then alpha-amylase is the optional one. Glucoamylase does the conversion to fermentable sugar and is the enzyme you cannot skip on a starch base. Alpha-amylase liquefies the starch first and lifts your yield. On a sugar or molasses wash you need neither.
Which Distiller's yeast works in cold weather? Gin Distiller's Yeast, rated from 12°C. It is the only Saccharomyces bayanus strain in the range, and bayanus is a cryotolerant species. Whiskey, Rum and Vodka Distiller's Yeast are all rated from 20°C and will slow badly or stall below that.
How much of a 450 g nutrient tub does one batch use? A 25 litre sugar wash takes 150 g of Light Spirits or 75 g of Dark Spirits, so a tub is three light batches or six dark ones. Fruit and molasses washes use less: 100 g light, 50 g dark.
Is the Distiller's Range worth it for a sugar wash vodka? Not really. If the wash is plain sugar and the spirit gets carbon filtered, the strain's congener profile is largely stripped out and you have paid for character you then removed. The range earns its price on grain, potato, molasses and fruit, where the yeast's contribution survives into the bottle.
Where to start
If you are fermenting grain, molasses or potato and using a pot still, the Distiller's Range is the right shelf for craft distilling. Pick the yeast by spirit, check its temperature floor against where your fermenter actually sits, dose the nutrient off the table above, and run the enzymes in order if there is starch involved.
If you are making sugar wash vodka and filtering it, save your money and stay on turbo yeast. That is not us being modest about the product, it is just where the value sits.
Everything in the range is in the specialty yeast, nutrients and enzymes collection, and if you are not sure which combination suits your setup, our team in Brisbane would rather talk it through than have you buy four sachets and guess.
