Made from wood, often birch or beech, yeast rings or logs were used by farmhouse brewers to harvest and dry kveik yeast to use in future brews. Evidence suggests that in as early as the 1500s yeast rings were also hung from a pole outside breweries to indicate the brew was successful and ready for consumption.
You don’t need a yeast ring these days but they are rather beautiful. Plus you’ll feel ultra authentic using such a traditional tool in your farmhouse brewing. Simply drag the yeast ring through the krausen of a fermenting beer, and then hang up the ring to dry. This is usually done several times to build up the yeast reserves. To reactivate the kveik the ring is then dunked into the wort of the new brew.
