Saccharomyces Cerevisiae – Perfect for light, fruity red wines for early consumption
CR51 will enhance ripe berry fruit flavours in light and fruity red wines and introduce a velvet texture perfect for Valpolicella and especially for Beaujolais style wines. This strain has an almost unique ability to confer a smooth even ‘silky’ quality to the wine, perfect for early consumption young reds.
CR51 is a medium rate fermenter with optimal temperature between 22 to 30ºC (72 -86ºF) which will ferment to 13.5% abv. ethanol. Low to medium foaming strain with low volatile acid and SO² production
Young’s All Purpose Red Wine Yeast is a fantastic, multitalented strain that is capable of working with and enhancing each varietals distinctive character. This steady, stable fermenter will deliver a soft yet well structured red wine. You can expect consistently high results when using this yeast, exceptional when producing fruity reds. Whilst only imposing subtle aroma and flavour compounds on to your wine, the results will show full expression of the grape’s
individual character. Anticipate medium to full bodied wines with good length of palate and a long finish, with the ability to ferment up to 15% ABV, this is a good all rounder when you are unsure which strain to use.
Alcohol tolerance: 15% v/v
Glycerol production: 5g/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
Saccharomyces Cerevisiae – Exceptional strain for full fruit varietal and country red wines promoting good structure, balance and colour.
The majority of yeast strains strip out fruit flavour and colour from the must, not so with VR21 which is particularly noted for preserving and retaining the natural fruit characteristics of the grape / country fruit and enhancing palate length.
VR21 is a relatively neutral strain producing subtle levels of aroma and flavour compounds, allowing full expression of varietal / country characteristics whilst enhancing colour, wine structure and balance.
VR21 is an ethanol tolerant killer strain, capable of fermenting to 15% abv. ethanol. Good production of glycerol, low volatile acid production, zero sulfur dioxide formation and low foaming.
VRE21 is capable of fermenting between 59 – 86°F but best results are achieved when a temperature between 68 – 75.2°F is maintained, unless cold fermenting is desired for flavour/aroma development.
