Nahthan, as a fellow Nathan, I have to say that you underrate the Union Jack.
Everything you say is dead on, and I don't know that I have anything to add to the description but superlatives.
I had this at the Toronado yesterday, and I must say that it was the best-balanced D-IPA I've ever had (hmm. maybe it's just an IPA, which it seemed like. Anyone know the ABV? I thought 8 was high, but that's what I've seen elsewhere...they don't have info on the brewery website). You got that hit of great aroma at the beginning, but it was a perfectly smooth drink with a great finish. I really, really hope that they put this into permanent rotation. All you west coast guys, go out and demand this in your beer bars. It was the most refreshing beer I've had in a couple of years (including when I used to live in Oxford, UK).
