As I'm not from the States (and the US used to produce truly dreadful stuff masquerading as beer), I'm not familiar with any of the brands you posted earlier, except for the Innis & Gunn range.
They are an extremely good Scottish company, (and actually do very well in both Canada and the US) and produce some terrific beers. Indeed, I would consider myself a big fan of their beers.
If the other beers you mentioned can be considered the equal of Innis & Gunn, then I am certainly open to the idea of sampling them. Moreover, I am delighted to learn that microbreweries of quality are now increasingly a feature of life in many parts of the US; this is very good news indeed.
I&G is excellent! They have some hard to find products of theirs (limited editions) that are even better than the regular products. The others I posted about definitely stack up to I&G in terms of overall quality, though of course, taste is very subjective and my recent purchases were a pretty wide range of styles.
Microbrews/breweries are indeed on the map. Heck, you can go into a large, mainstream grocery and find unique and excellent products vs. years ago where only a few liquor stores carried anything, and even then it was a small section with less than a dozen choices. Funny enough, our pattern of eating out is slightly dictated by the beer (and/or wine/other) options but that rarely limits us, especially around this area where local restaurants really support the local breweries (FWIW, I live in the St. Augustine area which has a really interesting history, and very good about supporting the local economy).
Oh, Oberon! I miss it dearly! I lived in Michigan for many years, and in the summertime it was on tap nearly everywhere. It was my go-to beer if I didn't want to make a decision (and often even when I did). Alas, Bells is not distributed in California.
That is a bit of a bummer, its a great beer. I meant to mention above, Ive seen the Two Hearted Ale at quite a few stores, Ill have to make a point to get it now.
