Well for the six moths that I have been brewing, I have put varying amounts of Cluster in pretty much everything. Here is what I've found. 1. If I don't overdo it, I get a nice clean bitterness in less malt driven(is that a thing?) beers. 2. If I do hit it too hard, particularly at first boil, I can get quite pungent, harsh tasting beer. 3. I REALLY like how it works with Kazbek(Particularly in a darker beer with lower IBUs), 4 . It just plain works with Cascade and Mandarina at ipa(ish) levels. Just some random thoughts, when I break in my new Digiboil(bought myself a birthday present), it will be with an all Cluster Cream Ale(brewed with lager yeast)... WHat do you guys(or gals) think? I'm still pretty new to this stuff, what else does it work well with? I really like the smell of it.
