Nitrogen charged Three Philosophers. Okay. I like the regular carbonation version plenty enough. Bought in a 4 pack of 16 oz cans at a Ft. Worth Total Wine last year. Pour into a Chimay glass gives caramel colored body with a creamy head of very fine bubbled foam that settles quickly. The drink is likewise creamy at the beginning followed by lightish figs, cherries, malt, syrup and a bit of grain. Decent enough, I would buy again. But that is if the regular version is not available.
