Poured this bad boy tonight expecting some thick motor oil that had had a strong alcohol aroma being 25 proof. Poured thinner than expected with not one little hint of head whatsoever. At a blind tasting I wouldn't expect this to be over 8%, after finishing the bottle it showed that it was 12.5% undoubtedly. Absolutely stellar beer, worth experiencing once. I would never spend MSRP for a second one, but it would be great for any beer tasting.
