Product Overview

Lallemand "West Coast Ale" yeast is known for its clean, neutral flavor profile and strong attenuation. With no overwhelming characteristics, this yeast lets your grain and hop choices shine! 
Lallemand BRY-97 gives you a quick start and vigorous fermentation, which can be completed in 4 days if kept above 63° F. The aroma is slightly estery, almost neutral and doesn’t display off-odors when handled properly. Because of its high flocculation, it may slightly reduce hop bitterness levels. Best results when used at traditional ale temperatures (62 - 72° F) and after rehydration in the recommended manner (see package for re-hydration procedure).
1. Origin
BRY-97 American West Coast Yeast was selected from the Siebel Institute Culture Collection and is used by a number of commercial breweries to produce different types of ale. The propagation and drying process have been specifically designed to deliver high quality beer yeast that can be used simply and with reliability to help produce ales of the finest quality.
No colours, preservatives or other unnatural substances have been used in its preparation. The yeast is produced in ISO 9002 certified plants.

2. Microbiological Properties
Classified as Saccharomyces cerevisiae
A top fermenting yeast.
The active dried strain has a typical analysis:
Percent solids 93 – 95 %
Living yeast cells ≥ 5 x 109 per gram of dry yeast
Wild yeast < 1 per 106 yeast cells (Lysine method)*
Bacteria < 1 per 106 yeast cells*
Finished products are only released to the market after passing a rigorous series of tests.
*according to ASBC and EBC methods of analysis

3. Brewing Properties
Quick start and vigorous fermentation, which can be completed in 4 days above 17 °C.
Medium to high attenuation,
Fermentation rate, fermentation time and degree of attenuation are dependent upon inoculation density, yeast handling, fermentation temperature and the nutritional quality of the wort.
BRY-97 American West Coast Yeast is a flocculent strain. Settling can be promoted by cooling and use of fining agents and isinglass.
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
Best when used at traditional ale temperatures after re-hydration in the recommended manner.

4. Usage
When 100 g active dried yeast is used to inoculate 100 litres of wort, a yeast density of 5-10 million cells per millilitre is achieved. A brewer may experiment with the pitching rate to achieve a desired beer style or to suit processing conditions.
Sprinkle the yeast on the surface of 10 times its weight of clean sterilised (boiled) water at 30 – 35 ºC.
Do not use wort, or distilled or reverse osmosis water as loss in viability might result . GENTLY brea any clumps to ensure that all yeast is 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 – 35 °C. Then adjust temperature to that of the wort and inoculate without delay.
Attemperate at steps of 5 minute intervals of 10 ºC 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 10 °C 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.

5. Storage
All active dry yeast should be stored dry and below 8 ºC. The packaging should remain intact.
BRY-97 American West Coast Yeast will rapidly lose activity after exposure to air. Do not use packs which have lost vacuum. Opened packs must be re-closed, stored in dry conditions at less than 4 ºC and used within 3 days.
Do not use yeast after the expiry date which is printed on the pack
