We found this place by chance, and I was really pleased we did. While we didn't eat there we sampled a few ales and had a good chat with the two servers about the brewery and its merchandise..
During the course of my Californian trip I sampled over 30 different ales, and Etna's Classic Gold topped my list of Pale Ales while its Phoenix Red scored highly in the Amber Ales category. My wife really liked Rustlers Revenge but disliked intensely the berry-flavoured Blonde ale.
Etna has a good range of merchandise all featuring its Eagle logo. We bought a glass which survived the trip back to England but the brewery had sold-out its stock of large T-shirts. Maybe next time.
