With dinner, I opened Rochefort 6, a Belgian Strong Ale, with an ABV of 7.5%. This is a wonderful beer from a Trappist brewery and you can taste sweetness and dark fruit (plum / prune / raisin). This went excellent with dinner and was one I had to slow down to enjoy as it is very drinkable.
I next tasted Rochefort 8, a Belgian Strong Dark Ale, with an ABV of 9.2%. This pours a dark muddy color with a head that quickly recedes. While not a bad beer at all, I enjoyed 6 much better. 8 has a nice aroma and is sweet, but it is not as drinkable as 6.
Rochefort 10, a Quadrupel Ale, with an ABV of 11.3%, was the final beer of the evening. This is a fantastic beer and I thought close to 6 in the flavor profile, but with more alcohol. It does not have a taste of alcohol, which is well hidden by the complex taste of malt sweetness, dark fruit (plum/prune/raisin) and molasses. This is a very rich tasting beer and it is one to be slowly consumed and enjoyed. These were great Christmas presents from my wife and I enjoyed them.
