I've had a 5 gallon all-grain batch of John Palmer's Elevenses in primary for just over a week. When I was brewing, I haphazardly dumped twice the prescribed amount of bittering hops (German Northern Brewer) in for the full 60 minutes. The recipe asks for 0.6oz, and I added the full 1oz sachet.
Upon testing the gravity last night I tasted the beer and it's very bitter, but otherwise good. Is there anything I can do, adjuncts I can add, hops I could add to secondary that might mask or "fix" this excessive bitterness I've induced? It's got a bit longer to go in primary before racking.
