A yeast nutrient that has garnered headlines in Europe and elsewhere is available to professional brewers in the United States and Canada.
Servomyces, which has been credited with dramatic
increases in yeast viability and overall beer flavor, is being sold to
North American brewers exclusively through White Labs Inc., a major
manufacturer of liquid yeast for brewers and winemakers.
"We are excited about this product, because we
know it will make brewers lives a lot easier and more
productive," said Chris Mueller, White Labs Vice President.
"We expect that Servomyces will become an industry standard, both
here and abroad."
Developed by a team of scientists at Munich
University and Weihenstephan, in conjunction with Lallemand, the
nutrient is being used widely in Germany, the United Kingdom, Sweden,
and Denmark, among other countries.
Brewers in Japan and Africa have also experimented
with the nutrient and reported outstanding results.
Brewers in these countries have reported a number of
positive outcomes, including fermentation that was almost five days
faster than normal; better flocculation; and improved yeast viability.
Users have also reported that Servomyces has resulted in the elimination
of harsh sulphury notes and the reduction in the level of diacetyl in
the end of primary fermentation.
Plus, the beer has a smoother overall flavor.
The nutrient, which is patented, is unique because it
is a biological substance without chemicals or additives. Because it is
natural, it falls within the Rienheitsgebot, or German brewing laws.
In its own independent tests, White Labs found that
Servomyces generated 1/3 more yeast growth and accelerated fermentation.
Each packet has enough nutrient for 10 barrels. It
should be used in each batch of beer. The easy-to-use product is added
during the final 10 minutes of the boil.
White Labs offers a steep volume discount on this
product. The normal price per package is $5.95. But brewers save
$24 when they buy 20 packages for $95. Call 1-888-5-Yeast-5 for more information.
