I had a pale ale the other day from a brewery I rather admire that I could not finish the other day and the reason was because it was brewed with a heavy amount of dark caramel malts and it clashed with the hops for my pallet. I’m sure there are folks out there that love that flavor in a beer but I can’t stand it. So for me, Crystal 60 does not belong in a pale ale, IPA or IIPA but your mileage will vary depending on your preference.
For those who want to try something kinda like crystal but not exactly, check out the Great Western Sacchra malts. I’ve been working with Sacchra 50 and I really like it. Kind of a cross between crystal and Vienna.
