BRY-97 American West Coast Beer Yeast
IPAs, Porter, Stout, Fruit Beer
Top fermenting yeast
Quick start and vigorous fermentation, which can be completed in 4 days above 17 °C.
The aroma is slightly estery, almost neutral and does not display malodours when properly handled. It may tend, because of flocculation, to slightly reduce hop bitter levels
When 100 g active dried yeast is used to inculate 100 litres of wort, a yeast density of 5-10 million cells per milliliter is achieved. A brewer may experiment with the pitching rate to achieve a desired beer style or to suit processing conditions.
Springkle the yeast on the surface of 10 times its weight of clean sterilized (boiled) water at 30-35C. Do not use wort, or distilled or reverse osmosis water as loss in viability might result. Gently break any clumps to ensure that all yeast in contact with the rehydration medium. Do Not STIR. Leave undisturbed for 15 minutes then suspend the yeast completely and leave it for 5 more minutes at 30-35C. Then adjust temperature to that of the wort and inoculate without delay.
Attemperate at steps of 5 minute intervals of 10C to the temperature of the wort by mixing aliquots of wort. Do not allow attemperation to be carried out by natural heat loss. This will take too long and could result in loss of viability or vitality.
Temperature shock at greater than 10C will cause formation of petite mutants leading to long term or incomplete fermentation and possible formation of undesirable flavours.
BRY-97 American West Coast Yeast has been conditioned to survive rehydration. The yeast contains an adequate reservoir of carbohydrates and unsaturated fatty acids to achieve active growth. It is unnecessary to aerate wort.
Storage: Store in cool (< 8C), dry conditions. If opened sachets must be sealed and stored at 4C and used within 3 days of opening.
