Brewed another 7.5 gal batch today, I hope it turns out like the ale I'm trying to clone. Hammerhead is the first Microbrew I tried many years ago. I live near a Mcmenamin's brewery so have enjoyed many of their brews. I have been brewing 7.5 gal batches since I seem to be able to consume and give away faster than I have free time to brew! So I have an Oatmeal Stout a few days from bottling followed by the one I brewed today.
