Diamond Lager Yeast

Description

LALBREW® DIAMOND LAGER YEAST

LalBrew® Diamond Lager yeast is a true lager strain originating in Germany. Chosen for its robust character, LalBrew® Diamond Lager yeast delivers excellent fermentation performance, and has the ability to  produce clean, authentic lagers. Traditional styles brewed with the Diamond include but are not  limited to Munich Helles, Dortmunder Export, German Pilsner, Bohemian Pilsner, American Pilsner,  Vienna Lager, Oktoberfest/Märzen, Dark American Lager, Munich Dunkel, Schwarzbier, Traditional Bock, Doppelbock, Eisbock and California Common.

QUICK FACTS

  • Beer Styles:  Lagers
  • Aroma:  Neutral
  • Attenuation:  High
  • Fermentation Range:  10 - 15°C (50 - 59°F)
  • Flocculation:  High
  • Alcohol Tolerance:  13% ABV
  • Pitching Rate:  100-200g/hl to achieve a minimum of 5-10 million viable cells/ml

MICROBIOLOGICAL PROPERTIES

Classified as a Saccharomyces pastorianus, a bottom fermenting yeast.
Typical Analysis of LalBrew® Diamond 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

BREWING PROPERTIES

In Lallemand’s Standard Conditions Wort at 12°C (53.6°F) LalBrew® Diamond yeast exhibits:

  • Vigorous fermentation that can be completed in 5 days
  • High attenuation and High flocculation
  • Neutral Flavor and Aroma, typical of traditional Lagers

The optimal temperature range for Diamond yeast when producing traditional styles is 10°C(50°F) to 15°C(59°F)

Fermentation rate, fermentation time and degree of attenuation are dependent on inoculation density, yeast handling, fermentation temperature and nutritional quality of the wort.

USAGE

The pitch rate will affect the fermentation performance and flavor of the beer. For Diamond yeast, a pitch rate of 100 – 200g per hL of wort is sufficient to achieve optimal results for most fermentations. More stressful fermentations such as high gravity, high adjunct or high acidity may require higher pitch rates and additional nutrients to ensure a healthy fermentation. 

REHYDRATION

Rehydration of Diamond in sterile water is recommended prior to pitching into wort in order to reduce stress on the cell as it transitions from dry to liquid form. For many fermentations, this stress is not significant enough to affect fermentation performance and flavor, so good results may also be achieved when pitching dry yeast directly into wort. We highly recommend rehydration in harsher fermentation conditions such as high gravity or sour wort where the added stress of dry-pitching is more likely to have a greater impact on the finished beer. Use of a rehydration nutrient such as Go-Ferm Protect Evolution has been shown to improve fermentation performance for difficult fermentations.

Rehydration guidelines are quite simple and present a much lower risk of contamination than a starter, which is unnecessary when using the recommended pitch rate of dried active yeast.

Sprinkle the yeast on the surface of 10 times its weight in clean, sterilized water at 25-30°C (77-86F). Do not use wort, or distilled or reverse osmosis water, as loss in viability may result. Stir gently, leave undisturbed for 15 minutes, then stir to suspend yeast completely. Leave it to rest for 5 more minutes at 25-30°C (77-86F).

Without delay, adjust the temperature to that of the wort by mixing aliquots of wort with the rehydrated yeast. Wort should be added in 5 minute intervals and taking care not to lower the temperature by more than 10°C at a time. Temperature shock of >10°C will cause formation of petite mutants leading to extended or incomplete fermentation and possible formation of undesirable flavors. 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.

Inoculate without delay into cooled wort in the fermenter. Diamond yeast has been conditioned to survive rehydration. The yeast contains an adequate reserve of carbohydrates and unsaturated fatty acids to achieve active growth. It is unnecessary to aerate wort upon first use.

STORAGE

Diamond yeast should be stored in a vacuum sealed package in dry conditions below 4C° (39°F). Diamond will rapidly lose activity after exposure to air.

Do not use 500g or 11g packs that have lost vacuum. Opened packs must be re-sealed, stored in dry conditions below 4°C (39°F), and used within 3 days. If the opened package is re-sealed under vacuum immediately after opening, yeast can be stored below 4C° (39°F) until the indicated expiry date.

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