Has anyone used Brewer's Gold for flavor and/or aroma? I have!
I'd planned on making a Ballantine IPA clone, so I bought some Brewer's Gold hops. I never did get around to making it (though I still will), so they were just sitting in the fridge. I'd read that they were generally not well received for anything but bittering, that they had a really strong flavor. However, I made a stout with some Crystal 120, and to balance out that heavy caramel flavor, I used an ounce of BG for 20 minutes and then half an ounce for 5. Wow! They have an unusual, pungent floral character to them. I can see how in many beer types they wouldn't be a great choice, but as a balance to the heavy caramel and toasty flavors of this strong stout, it's awesome.
The experience inspired me to experiment a little more. I made an IPA and used 2 oz Columbus 12.2 % (60 minutes) + 2 oz Cascade 6% (?) (20 minutes) + 2 oz Sterling ?% (5 minutes). After about three weeks in primary I tasted it, and I really like it. Of course, it isn't unheard of to use what are traditionally lager hops in ales, but it is a little unusual.
