LALLEMAND Novalager

Description

LalBrew NovaLager™ is a true bottom-fermenting hybrid Saccharomyces pastorianus yeast selected to produce pure lager beers with typical flavors and superior fermentation performance.

LalBrew NovaLager™ is a robust lager strain with ideal characteristics for lager production. Its characteristic organoleptic profile is very pure with light esters over a wide temperature range.

LalBrew NovaLager™ was selected using conventional, non-GMO breeding methods to obtain a new Saccharomyces cerevisiae x Saccharomyces eubayanus hybrid strain that defines a new lager line. This strain is a low VDK/diacetyl producer and utilizes a patented technology from the University of California Davis (USA) that inhibits the production of hydrogen sulfide (H2S), thereby reducing the maturation time associated with lager production.

Microbiological properties:
Classified as Saccharomyces pastorianus, bottom-fermenting yeast.

Percentage of solids: 93% to 97%.

Viability:  ≥ 5 x 109 CFU per gram of dry yeast.

Wild yeast: < 1 per 106 yeast cells

Diastaticus not detected

Bacteria: < 1 per 106 yeast cells

Fermentation properties:
In a wort at 12°C, LalBrew NovaLager™ exhibits:  A vigorous fermentation that can be completed in 6 days.

High attenuation and medium flocculation.

Aromas and flavors are pure with light to medium esters, no sulfur. This strain is POF negative.

The optimal temperature range for LalBrew NovaLager™ is 10-20°C for traditional styles.

Lag time, fermentation time, attenuation and flavors depend on seeding rate, seeding methods, fermentation temperature and nutrient qualities of the wort.

Seeding rate : 50 to 100g/HL.

Alcohol tolerance: 13%.
