Eitrheim

Rooted in the brewing heritage of Norwegian farmhouse ales, our Multi-Strain Kveik Yeasts are crafted blends of authentic kveik cultures. Each strain contributes its distinct character, creating a rich, complex and layered flavor at high temperatures. At lower temperatures you can expect a more neutral flavor profile. Depending on the temperatures our yeast will ferment in 2-10 days.

USING EITRHEIM

Eitrheim is a flexible multi-strain kveik culture suited to a range of brewing and production environments. It can be used across different fermentation setups, with fermentation behaviour influenced by temperature, pitch rate and wort conditions.

STORAGE & HANDLING

Store sealed packages in dry conditions below 6°C / 43°F. The product can be transported and kept at room temperature for up to one month. Opened bags should be re-sealed, stored dry below 6°C / 43°F and used within three days. Do not use damaged sachets.

ABOUT THE ORIGIN

Eitrheim kveik originates from the Hardanger region of Western Norway, an area with a long farmhouse brewing tradition. The culture was preserved through generations of local brewing, where kveik was harvested after fermentation and kept for use in subsequent brews.
