Tonight I had the Cloudwater DIPA V6 and the V7, side by side. There have the same grain and hop bill, differing only in the yeast used. V6 has the Wyeast Vermont strain, and V7 has the JW Lees strain. Of course they were very similar, but V6 just edged it for me, as it was slightly smoother. Yesterday I had Zoji by Track Brewing, which was a really top notch BIPA, one of my favourite styles, and is vying with Arcade Nation for my favourite commercial BIPA. I also had a Zintuki by Wild Beer Co, which was a perfectly acceptable sour beer but nothing special, I've certainly had better from them. Also on the sour front was Blue Sky Blue Sea by Siren, a brewery I really appreciate since trying their Calypso. It is a gose brewed with seaweed and cloudberries. I haven't tried a goze before, but really enjoyed the balance of salt, sour and fruitiness, so I hope to try some more traditional versions of the style. Also by Siren, I tried their Vermont Tea Party IPA, brewed with Earl Grey and lemon zest. This was a really stunning American style IPA, and has helped sure up my belief that Siren is one of the most innovative and ground-breaking breweries in the UK today. That is enough liver exercise for me tonight though, as tomorrow I'm going to London for a reunion, and managed to convince the group to meet at the Craft Beer Co for drinks before dinner.
