Mangrove Jack's M84 Yeast 10g

Bohemian Lager is a classic bottom-fermenting, continental lager strain that produces elegant, well balanced beers. Bohemian Lager Yeast is characterized b y its dry and clean palate, typical of traditional Czech brewing. This strain confers smooth, subtle yeast characteristics with muted fruit notes, resulting in refreshingly crisp lagers with expressive hop character. While rich and chewy, the beers fermented with this strain will not be sweet, but may have an elusive sweet malt flavor in the aftertaste. Lagering periods as short as 4 weeks may produce acceptable beer, but allowing beer to lager 6-8 weeks will result in beer that is richer, smoother, with a more refined aroma and flavor.

Suitable for all types of European Lagers. Ideal for Czech Pils, German Pilsner. Mangrove Jack’s Bohemian Lager Yeast M84 is very similar to Wyeast 2124 Bohemian Lager or WLP830 German Lager. The recommended fermentation temperature range of this strain is 50° to 59°F.

Fermentation Observations:

Starts quite quickly for a lager strain, building a thick krausen by 24 hours. Reaches final gravity in 2 weeks except for strong worts, which will require longer secondary fermentation. Lagering period with this strain can be fairly short, as little as 4 weeks with good results.

Aroma Characteristics:

Classic Bohemian Pilsner strain aroma and flavor characteristics can be expected.

Flavor/Mouthfeel Characteristics:

Earthy spiciness of both noble hops and Pilsner malt will be enhanced and supported by moderate to full body. In wort from simple grist bills, delicate malt flavors will survive. Beer fermented with this strain is generally rich and chewy without being heavy at all. Light and delicately balanced beers call for this strain.

Higher Alcohol Beers:

This strain will preform reasonably well in higher alcohol beer production, but only to 9% alcohol. Beer of over 7% alcohol will be slightly sweet, and the alcohol may be a bit hot.

Usage:

1. In most cases, Mangrove Jack’s Craft Series Dry Yeasts can be used at a rate of one 10g pack for up to 6.6 gallons of wort, with the following exceptions: Ales with original gravity over 1.050, use 2 packs per 6 gallons. Lagers that will be fermented below 57°F, use 2 packs per 6 gallons.

2. REHYDRATING: Although Mangrove Jack’s Craft Series Yeasts do not require pre-hydration, cleaner and more professional results may be produced if rehydrated before pitching. For all strains except the Bohemian Lager, add the sachet contents to 100ml of preboiled clean water that has cooled to between 86-95°F (for Bohemian Lager the rehydration temp should be between 68-77°F) Stir gently into a yeast cream for about 10 minutes then pitch directly into wort. Alternatively the dry yeast can be added directly into the wort by sprinkling onto the surface and leaving to stand for 10-15 minutes before stirring.

3. STORAGE: Store in original packaging below 50°F (we keep it in the refrigerator) for optimum 30 month shelf life.
