Brand: Mangrove Jack’s
Why Brewers Love It
M12 Kveik Ale is a Norwegian farmhouse yeast prized for its speed, strength, and versatility. It ferments clean at lower temperatures and develops bold citrus esters when used warm. Capable of handling high alcohol levels, it’s a flexible strain for both traditional farmhouse ales and modern experimental beers.
