Mangrove Jack’s M66 Hophead Ale Yeast – 10g Sachet

Elevate Hop Aroma and Flavor in Hazy, Juicy IPAs

Mangrove Jack’s M66 Hophead Ale Yeast is a specialized top-fermenting strain designed to maximize hop expression in modern, hop-forward beer styles. This unique yeast and enzyme blend enhances the release of aromatic compounds from late hop and fruit additions, making it ideal for New England IPAs, Juicy IPAs, Hazy IPAs, American IPAs, and American Pale Ales. The result is a beer with intensified hop aroma and flavor, complemented by a moderate, well-balanced ester profile that adds subtle complexity without overshadowing the hops.

With medium attenuation and high flocculation, M66 ensures a clean fermentation and a moderately dry finish, while retaining a good level of mouthfeel to prevent the beer from being too thin. Its high alcohol tolerance of up to 10% ABV makes it suitable for stronger IPA styles, allowing brewers to craft bold, flavorful beers that showcase the full potential of their hop additions.
