Gift and Request II - Robust Porter

A robust porter brewed by request with a gift certificate. Replaced northern brewer hops from previous batch with a large cascade and crystal late addition. Replaced 1056 with 1272 for more character. Added special B in hopes of achieving character similar to Smuttynose robust porter. Added Victory for toasted flavor.
