second guessing flavor though, that's all up to you!
Often big beers like barley wines or big Belgians they have no. head or lacing.
The only way to determine the alcohol content is to take a gravity reading at the beginning(OG) and taking a gravity reading when it is finished (FG)
Then ( OG - FG ). X 131.25= ABV
