As per an earlier post, for a very peated blend, try Islay Mist. For under $25 you're getting 50% Laphroaig. Super value.
As for Atholl Brose, technically, it isn't a whisky and is a liqueur. It's bottled and 35% ABV and has additives. Both prevent it from being called whisky. That said, it is one of the most complex, high-quality and marvelous liqueurs in the world. Compare it to Glayva or Drambuie and the only comparison is that there is none! The base spirit is Benromach now. Phenomenal!
