Funny you mention Sorachi Ace, I was just browsing some websites tonight and there is an IPA from Cape Ann Brewing out of Gloucester, MA that their website says they use Chinook and Sorachi Ace. It is called Fishermans IPA. I had the beer about 2 years ago at a local beerfest and thoroughly enjoyed it. Unfortunatly at that time I was not much into brewing and critiquing beer. Being that you are in TX I'm not sure if you can pick one of these up, but I would assume it could give you an idea of the hop variety.
If you end up brewing with it, please let me know what your thoughts are of it.
