Imake are changing the name of Vintners Harvest to Mangroves Jacks yeast
Saccharomyces Cerevisiae – Perfect for light, fruity red wines for early consumption
Vintners Harvest CR51 Wine Yeast 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 wine yeast strain has an almost unique ability to confer a smooth even ‘silky’ quality to the wine, perfect for early consumption young reds.
CR51 wine yeast is a medium rate fermenter with optimal temperature between 22 to 30°C (72 -86°F) which will ferment to 13.5% abv. ethanol.
Low to medium foaming strain with low volatile acid and SO2 production
Do not re-hydrate Vintner’s Harvest yeast before addition, but add directly to the must/juice noting the following:
To avoid extended lag time and risk of bacterial contamination ensure must/juice temperature is above 20degC (68degF) for the start of fermentation and for at least the first 24 hours.
Control fermentation temperature within the range specified for each strain. As a general rule ferment between 20 - 24degC (68-75degF) unless cold fermenting is desired for flavour/aroma development.
All yeast strains are sensitive to excessive osmotic pressure, incorrect pH and nutrient insufficiency. Due care and attention to must/juice preparation is important.
