Munich Classic Yeast

Munich Classic is a Bavarian wheat beer strain that can easily express the spicy and estery aroma profile typical to German wheat beer styles. This strain is simple to use over a wide range of recipe variations and fermentation conditions, making it a great choice for a number of traditional styles of wheat beer. In classic open fermentation vessels, the yeast can be skimmed of the top in the traditional manner. Styles brewed with Munich Classic include but are not limited to Weizen/Weissbier, Dunkelweizen and Weizenbock.

MICROBIOLOGICAL PROPERTIES
Classified as a Saccharomyces cerevisiae, a top fermenting yeast. 
Typical Analysis of Munich Classic Yeast:

• Percent solids: 93% - 97%
• Living Yeast Cells  ≥  5 x 10⁹ per gram of dry yeast 
• Wild Yeast  < 1 per 10⁶ yeast cells
• Bacteria:  < 1 per 10⁶ yeast cells

Finished product is released to the market only after passing a rigorous series of tests
*According to the ASBC and EBC methods of analysis

BREWING PROPERTIES
In Lallemand's Standard Conditions Wort at 20°C (68°F) Munich Classic yeast exhibits: 

• Vigorous fermentation that can be completed in 4 days.
• Medium to High Attenuation and Low Flocculation.
• Aroma and flavor is balanced with prominent fruity esters and spicy phenol notes of banana and clove.
• The optimal temperature range for Munich Classic yeast when producing traditional styles is 17°C(63°F) to 22°C(72°F).

Fermentation rate, fermentation time and degree of attenuation are dependent on inoculation density, yeast handling, fermentation temperature and nutritional quality of the wort.
Munich Classic has an ABV tolerance of 9%.

REHYDRATION
Rehydration of Munich Classic is recommended for use, and will reduce osmotic stress on the yeast when rehydrated and pitched in liquid form. Rehydration guidelines are quite simple, and present a much lower risk of contamination than a starter, which is unnecessary with dried active yeast.

Sprinkle the yeast on the surface of 10 times its weight in clean, sterilized water at 30-35°C (86-95°F). Do not use wort, or distilled or reverse osmosis water, as loss in viability will result. DO NOT STIR. Leave undisturbed for 15 minutes, then stir to suspend 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 in steps at 5-minute intervals of 10°C 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 flavors.

Munich Classic 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 upon first use.

When using Lallemand Brewing Yeasts, you may repitch the yeast just as you would any other type of yeast according to your brewery's SOP for yeast handling.

STORAGE
Munich Classic yeast should be stored dry below 10C° (50°F)

Munich Classic will rapidly lose activity after exposure to air. Do not use 11g packs that have lost vacuum. Opened packs must be re-closed, stored in dry conditions below 4°C, and used within 3 days. If the opened package is re-vacuum sealed immediately after opening, yeast can be stored for up to two weeks below 4°C.

Do not use yeast after expiry date printed on the pack.
