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 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.
Alcohol tolerance: 15% v/v
Glycerol production: 6g/L
Low production of volatile acids
Low production of SO
Viability: >1.0 x 10 CFU/g
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.
Acid reducing strain excellent for fruity white & blush country wines especially where residual sugars are desired. MA33 has the ability to metabolize between 30 and 35% of malic acid making this strain the perfect choice for country fruits which are naturally high in acid. Reducing malic acid will soften the wine and give a vin nouveau character for early consumption with a balanced palate.
MA33 is also noted for its production of fruity esters and fusel oils conferring fresh fruity character to the wine. There is an increased chance of Malolactic fermentation by lactic acid bacteria following MA33 fermentation. MA33 is a killer-sensitive strain. It is a good fermenter between 18 and 27OC (64 -80OF), with a rapid onset to fermentation although can exhibit a slow late fermentation profile and may require aeration after 10 – 12 days. Will ferment up to 14% ABV. ethanol providing the pH is above 3.2
