BeerBorg

Does anyone have any experience with them? I am thinking of using for a cucumber beer, ALC with cucs, and cyrstal for 20min.

I've used small amounts in a number of my IPA's...still have a small amount in the freezer.
I believe they are somewhat on the lower end of bittering and I personally don't think they add that much to IPA's but are similar to Mt. Hood (I think). I've seen quite a few pilsner recipes that call for crystal.

Personally haven't used them, but here is part of their USDA profile.

"MAJOIR TRAITS: Similar oil profile as Hallertauer mittelfrueh; pleasant continental-type
aroma; suitable for flavoring beers and ales when Hallertaur-type aroma
is desired.
OTHER INFORMATION: Crystal is a half-sister of Mt. Hood (USDA 21455), Liberty
(USDA 21457), and Ultra (USDA 21484)."
