I'm considering brewing this for my next batch. I think it is a 6 gallon batch. Gonzo Imperial Porter is 7.8% ABV, when I plug the grain bill in to Beer Smith, with a 70% efficiency on a 6 gallon batch it esimates 7.5% ABV. If I drop it to a 5 gallon batch it jumps to 9.1% est ABV. I think I'm going to brew it as a 6 gallon batch, and I'm thinking of adding some espresso to the secondary. The reviews I've read indicate a coffee flavor. Have you brewed this yet? I would do a large dry hop for a beer with a high OG.
