Mangrove Jack's M44 Yeast 10g

With the craft beer movement being lead by the USA, there has been a demand for a yeast strain which emphasizes the expressive flavors of the unique ingredients used. US West Coast Ale Yeast is a high attenuating, top-fermenting strain that ferments with almost completely neutral attributes across a wide range of wart strengths and temperature ranges. It produces a moderately high acidity which allows the tangy citrus hop aromas to really punch through, while also enhancing toasted and dark malt characters. If you plan to use a lot of expensive flavorful hops as the prominent feature of your beer, use this yeast.

Suitable for American ales. This yeast produces an exceptionally clean flavor, ideal for when you want the hop character to really punch through. Ideal for American Pale Ale, American IPAs and Double IPAs, American Imperial Stout and more. Mangrove Jack’s US West Coast Ale Yeast M44 is very similar to Wyeast 1764 Pacman Yeast from Rogue. The recommended fermentation temperature range of this strain is 59° to 74°F.

Fermentation Observations:

Quick to start, this strain will linger through primary and secondary fermentation, achieving final gravity after 2 weeks. Krausen will be dense and creamy, occasionally voluminous. Patience in conditioning will reward brewers with a nicely dry, yeast -neutral beer.

Aroma Characteristics:

A very neutral strain, even when fermented in higher gravity worts and warmer temperatures. Tangy citrus and pine hops aromas will be enhanced, s well as toasted and dark malt aromas.

Flavor/Mouthfeel Characteristics:

Beers fermented with this strain will finish dry and crisp. This strain is at its best in hop prominent American style ales. Very light ales may turn out a bit stripped, thin or astringent if care is not taken with the mash to favor dextrins and avoid over-extraction. Acidity is moderately high, boosting hop flavors and creating a clipped finish.

Higher Alcohol Beers:

Remaining very neutral, and producing a bit of acid to balance alcohol and malt, this strain excels in strong ales with simple malt bills. Alcohol will be a dominant flavor and aroma constituent, and may be quite warming but not harsh.

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.
