Puriferm Carbon Turbo
This turbo yeast can produce 17-18% alcohol, using up to 7 kgs of sugar into 25 litres of wash.
Ready in 3-5 days
With addition of a high spec granular carbon, fermentation is almost odorless and the quality of the fermented alcohol is very high.
This fast yeast strain of Ethanol TT and can produce stronger alcohol while preserving better flavor characteristics.

Saccharomyces Cerevisiae – The ‘only strain’ for Germanic aromatic white wines.
AW4 is noted for developing powerfully fragrant, full spice aromatic wines and is a perfect match for Gewurztraminer and also recommended for Sauvignon and Semillon where the Oenologist requires a positive aromatic esters contribution from the yeast.
AW4 is a good fermenter across the range 14 to 30ºC (57 -86ºF), low foam formation and medium to high glycerol. It will ferment up to 14.5% abv. ethanol providing the temperature is held within the 20 – 25ºC (68 -77ºF) range and the pH is above 3.0
Youngs Ale Yeast is a customary example of a traditional top fermenting English Ale yeast and is used throughout the country in commercial breweries as well as by home brewers. The pure single strain culture has several outstanding characteristics such as it’s high temperature tolerance, high alcohol tolerance, relatively low risk of bacterial contamination and outstanding sedimentation characteristics, making it a consistently popular option, delivering reliable top quality Ale’s. You can expect a full bodied, fruity Ale with a hoppy, estery nose and palate. When using this yeast you can look forward to a high final gravity that delivers additional body, weight and a fuller flavour to competitor yeasts. Young’s Ale yeast can be sensitive to variations in fermentation temperature but where constant temperature is used it is a forceful strain with very strong fermentation and moderate attenuation properties.

Rehydration
During yeast manufacture, special processs are employed to promote very high leveles of the natural compound – Trehalose within the yeast.
Trehalose is a natural sugar produced within the yeast cells to protect itself during prolonged storage and stress conditions.
The very high levels of trehalose acheieved also remove the need for re-hydration before adding to must or wort – there is now no advantage in doing this even for high alcohol wines.
Saccharomyces Cerevisiae – For sweet white/blush and dessert wines. Produces high levels of desirable congeners during fermentation including aromatic thiols, imparting rich fruity aromatics, full body and ‘tropical’ flavor characteristics. CY17 is also noted for high glycerol formation, further enhancing sweetness.
This is a slow fermenter compared to all other strains in the Mangrove Jack’s range, typically taking up to 21 days to ferment table wines and up to 35 days for dessert wines. CY17 prefers a constant temperature in the 22 – 26ºC (72 -78ºF) range. Dropping the temperature below 15ºC (59ºF) two thirds of the way through fermentation will arrest fermentation making CY17 suitable for producing naturally sweet wines (both potassium sorbate and metabisulphite must be used to prevent re-fermentation).
CY17 is also excellent for sweet sparkling wines, but CL23 must be employed for the bottle fermentation stage.
Avoid free SO2 levels above 50 ppm and ensure pH above 3.2, CY17 is a delicate strain that must be treated with some respect. Pay particular attention to sterile winemaking conditions and a warm start to fermentation otherwise risk of bacterial contamination is increased. CY17 will happily ferment up to 15% abv. ethanol if such conditions are employed
oung’s Dessert / High Alcohol Wine Yeast is an exceptional strain that allows optimum wine quality to be achieved with each and every brew. It’s properties include an ability to ferment up to 18% ABV, rapid clearing, low foam formation, and the ability to ferment as low as 10°C means this is a reliable and easy to handle strain. You can expect a taste and aroma profile that will bring the natural grape flavours to the fore, it will also add a definite weight and depth to your wine, making it perfect for high alcohol sweet wines. Excellent across numerous varietals producing classic, true to type sweet, flavoursome wines with balanced mouthfeel and smooth finish, exuding the baked fruit flavours synonymous with high alcohol wines. Making well structured, clean wines that are a wonderful accompaniment to many after dinner treats is what this strain does beautifully.
