Convergent Evolution is a 2, 3 & 4 year blend of 75% Spontaneous Fermentation and 25% Mixed Fermentation red wine barrels.
This beer is in our cellar, and is no longer for sale. We occasionally make beers from our cellar available, so keep an eye out for a re-release.
Spontaneous fermentation is an extremely specialized method of inoculation where airborne microorganisms are introduced to the wort in our coolship, without direct intervention. By contrast, Mixed Fermentation relies on different kinds of yeast that we propagate in our lab in the brewery.
This beer is a blend of some barrels that were made using spontaneous fermentation, and some mixed fermentation barrels.

The final step before packaging our beer is one of the most important: blending.

Read on to learn about how we create the final version of our beers.

If you’re buying a special bottle why wouldn’t you want it to be the best it could be? Read on to learn more.
