Mighty Oak Ale is a summer seasonal from Samuel Adams, an amber ale aged in oak barrels. It seems to me that oak is easy to overdo, but Sam Adams has delivered a nicely balanced beer in Mighty Oak Ale. There are definite oak flavors, but it’s not overpowering or overly acidic at all. The aroma has a lot of caramel with some hints of vanilla. The middle is where you taste the oak, softened by vanilla, and the finish is sweet with raspberry and fruit with a little more vanilla from the oak right at the very end. This is a very nice beer, with a flavor that’s bigger and bolder than what you often find in a summer seasonal.
