Alcotec VodkaStar turbo yeast contains a high purity yeast strain, chosen for its ability to create very clean and neutral alcohol from a sugar/water wash. It will ferment to 14% in 5-6 days. Note that for making vodka from grains, you also need enzymes to break down starch components into fermentable sugars. If you use grains, rice or similar in the recipe – use Alcotec Vodka Turbo with GA instead and you may need to pre-treat the wash with Alpha Amylase enzyme. Temperature range is 20-25°C for maximum purity but it works up to 35 °C

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
Young’s Re-start Wine Yeast is the perfect strain for completing fermentations that are sluggish or have completely stopped. This yeast has the capabilities to kick start and dominate the fermentation, fermenting to dryness up to a possible 18% ABV. This innovative, fermentation-friendly yeast will start work quickly and produce low foam overcoming difficult fermentation conditions and delivering a consistently clean and fresh tasting wine. This strong, forceful strain is suitable for use with any red, white or rose wine it is easily handled and confers very neutral flavour and aroma characteristics. Due to it’s rapid re-activation properties it will avoid negative wine influencers such as excessive SO production, colour oxidation and flavour loss commonly associated with sluggish fermentations.

Young’s Bordeux Red Wine Yeast is truly a top quality strain that delivers outstanding home wine making results. Some red wine yeast strains on the market will strip out fruit flavour and colour from the must, however the complete opposite is true of this strain. Your wine will retain the viticulture and natural fruit characteristics of the grape and it’s synonymous claret colouring. This yeast will allow you make wines that are full of the balanced soft fruit flavour and character that is associated with traditional old world Bordeux reds. Expect pronounced dark fruit notes on the nose, as well as some spicy characteristics, well balanced wines with good palate length and intense fruit flavours. This medium foaming yeast has the ability ferment up to 15% ABV and produce truly sublime wines suitable for maturation.

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.
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.
