Took a little longer to get around to this; I’ve been battling a cold. Anyway, here’s what I’ve come up with:
Bell’s Hopslam is boozier, slightly less amber in color, and perhaps has more depth.
Troeg’s Nugget Nectar is thinner, has a nicer color, and cleaner on the palate.
That’s it! Not much else. They are both outstanding beers. And there’s no need to have a winner. Both are a pleasure to drink, and can stand the test of time.
