Saccharomyces Cerevisiae – Ideally suited for rich, full bodied red wines with exceptional flavour complexity.
Noted for exceptional depth and flavour complexity, R56 exhibits complex aromatics during fermentation conferring an old world quality which one might only expect from natural flora multiple strain fermentations.
Unusually for complex aromatic strains, R56 still respects the varietal character of the fruit and confers good structure and balance. R56 is also a high glycerol producing strain.
R56 is a medium rate fermenter with optimal temperature between 22 to 30ºC (72 -86ºF) which will ferment to 13.5% abv. ethanol.

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.

Saccharomyces Bayanus – Very good all round strain, best choice for high alcohol and fortified wines but also excellent for most country wines, sweet sparkling wines and ciders.
If you only had one wine yeast strain, this would be the strain because whilst being relatively neutral in character SN9 does introduce excellent weight and structure no matter the must or fruit and produces a congener profile that always compliments the wine.
SN9 is particularly good when fermenting flower or low fruit recipes which often lack vinosity, weight and depth.
SN9 is another strain noted for its robustness, being able to ferment to 18% abv. ethanol, tolerate high free SO2 and high levels of other stress factors such as organic acids, incorrect temperature and pH. But unlike CL23, SN9 adds weight and high glycerol production making the strain perfect for high alcohol sweet wines or where uncertain recipes are employed and fermentation reliability is a key factor or where low temperature fermentation down to 10OC (50OF) is required.
This strain is ‘fermentation friendly’ in that it produces zero foam, starts fermenting rapidly so avoids potential bacterial contamination and can be used to re-start stuck fermentations. SN9 is also the most osmotolerant and the fasting clearing of all Vintner’s Harvest strains.
SN9 is ideal for restarting stuck fermentations.
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.
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.
