ALE YEAST

Ales are typified by a rich, full-bodied profile with a fruity nose and taste. Each strain has unique characteristics, which can be enhanced or minimized depending on formulation and fermentation temperatures.

1007 German Ale Yeast.
Probable origin: Dusseldorf, Germany
Beer Style: Alt beer, American style wheat beers
Commercial examples may include: St. Stan Alt, Schlosser Alt, Frankenheim Alt, and Pinkus Alt
Unique properties - True top cropping yeast, low ester formation, broad temperature range affects styles. Will ferment cold; 55° F range, (13° C) producing lager characteristics including sulfur production. Style is noted for dry, crisp characteristics. Fermentation at higher temperatures (70-75° F, 21-24° C) may produce some mild fruitiness. Extremely poor flocculating yeast, generally remains significantly in suspension without treatment or filtration. Pad filtration is often difficult. Brewer's benefit from DE filtration or centrifuging. Maturation: Beers mature fairly rapid, even when cold fermentation is used. Low or no detectable diacetyl, alcohol tolerance approximately 11% ABV. Flocculation - low; apparent attenuation 73-77%. (55-68° F, 13-20° C)

3068 Weihenstephan Weizen Yeast.
Probable origin: Weihenstephan, Germany
Beer Styles: German Hefeweissen, Crystal weisse, Dunkel weisse, Weisenbock
Commercial examples may include: Ayinger Weissebeer, Tabernash Wheat, Sandwald, Erdinger Weisse, Schneider Weisse
Unique properties: Classic German wheat beer yeast, used by more German Brewers than any other strain in the production of Wheat beer. Properties dominated by banana ester production, phenols and clove like characteristics. Extremely attenuative yeast, which produces a tart thirst quenching finish. Extremely low floccing yeast remains in suspension readily with proteinacous wheat malt. Sometimes used in conjunction with lager yeast and kerausened to finish the beer and improve the overall dryness. High CO2 levels, typically at 2.7 - 3.2 volumes is desirable for best presentation. True top cropping yeast requires full headspace of 33%. Ester formation is significantly affected by aeration and pitching rates. Crystal weisse production typically requires DE filtration, may prove too difficult for Pad filtration only. Flocculation - low; apparent attenuation 73-77%. (64-75° F, 18-24° C)

3333 German Wheat Yeast. Subtle flavor profile for wheat yeast with unique sharp tart crispness, fruity, sherry-like palate. Flocculation - high; apparent attenuation 70-76%. (63-75° F, 17-24° C)

3724 Belgian Saison Yeast. Classic farmhouse ale yeast. Spicy and complex aromatics including bubble gum. Very tart and dry on palate with mild fruit. Finishes crisp and mildly acidic. Benefits from elevated fermentation temperatures. Usually slow to attenuate. Flocculation - low; apparent attenuation: 76-80%. (70-85° F, 21-29° C)

3787 Trappist High Gravity.
Probable origin: Westmalle, Belgium
Beer Styles: Doubles, Triples, Abbey, Beir de Grarde
Commercial examples may include: Westmalle, Rochfort, Chimay, Casteel
Unique properties: This strain produces intense esters and phenolic characteristics with complex fruitiness. Does not produce significant amount of iso-amyl acetate (banana esters) or bubble gum esters typical of many yeast of this style. Phenol and ester production are influenced by fermentation temperatures. Phenols tend to dissipate as beer matures. This type of yeast benefits from incremental feeding of sugars during fermentation, making suitable conditions for doubles and triples, to ferment to dryness with good alcohol tolerance approximately 11-12% ABV. True top cropping yeast with broad temperature range. Flocculation - medium; apparent attenuation 75-80%. (64-78° F, 18-25° C)

Commercial examples may include: Celis Wit, Hoegaarden, Blanc de Brugge
Unique properties: A yeast with complex flavor profile which produces a spicey phenolic character with low ester production. Phenols tend to dominate most flavors and dissipates with age. Ferments fairly dry with a finish which compliments malted and unmalted wheat and oats. Sometimes used in conjunction with lactic acid bacteria to produces a sharper finish. This strain may be a slow starting yeast with true top cropping characteristics. Flocculation is low, with yeast staying suspended with proteins in a well designed beer. Alcohol tolerance approximately 10-11% ABV. Flocculation - medium; apparent attenuation 72-76%. (62-75° F, 16-24° C)

PACKAGE INSTRUCTIONS
--------------------------------------------------------------------------
IMPORTANT INSTRUCTIONS - READ BEFORE USING
This package will require l-3 days to incubate prior to using. Incubate package one day for every month beyond the mfg. date stamped on package (for example, up to 1 month = 1 day incubation). Normal shelf life is six months if refrigerated. Some yeast will survive for 12 months or more if stored properly. For best results use when fresh.

TO START INCUBATION

Lay package on a table. Locate the bulged seal area of the inner package. Place the palm of one hand between the bottom of the package and the bulged seal. With your other hand, press firmly on the bulge to break the inner seal. You will know the seal is broken when the bulge is flattened. Mix the yeast and nutrients by kneading the package.

Shake the package well. Allow to incubate at 70-80ºF until the package swells to at least one inch thick.

NOTE: A STARTER CULTURE CAN BE MADE
To increase the pitching rate, boil one-third to one-half cup of malt extract in a pint of water to make a wort of S.G. 1.020-30. Boil wort for 15 minutes and cool. Add yeast and aerate well. Keep at 70-80º F Pitch at high krausen, about 12 hours. Agitate frequently to increase aeration.

To pitch the yeast: clean the container or package with sanitizing solution. Shake well. Open, and pour the yeast into the fermenter.

Aerate well by stirring vigorously. Seal fermenter with airlock. Keep at 75º F until fermentation begins. Then cool to desired temperature. Signs of fermentation should be evident within one day, depending on yeast strain, brewing procedures, and fermentation temperatures.

FERMENTATION TEMPERATURE RANGE

Ale yeast 60-72 º F; Lager yeast 46-58º F.

KEYS TO SUCCESSFUL FERMENTATION

A. Transfer yeast in active state (not after attenuated).\ B. Aerate well at each transfer.
C. Use more yeast for high-gravity beer..
D. Use the freshest yeast possible.
