I think it's quite an interesting observation that what is being made available by craft breweries, seasonally influences what we are brewing at home. "Golden Boy", "Paradox" I'm sure I've heard of others this summer, but I can't remember them off the top of my head.
Then I had a look through the "what are you brewing" thread... I've brewed 2 Blonde Ales, JT is on to mark IV, Denimglen is getting into it - there are others too. It's funny - Summer time 07/08 I brewed APA in December, Hefe on 6-1-08, Pils on 7-1-08, Koelsch 26-1-08, Hefe 19-2-08.
I find it interesting how seasonal the brewing really is - but more so, how trends influence the seasonal brew - last year Hefeweizen was the business - this year it's Blonde Ale.
Light ales are the business this year. Since 11/7 have brewed a kolsch and English Summer Ale (which were both closer to blondes) and brewing a blonde at the moment.
Can't say the commercials/crafts were any influence though, well not consciously anyway.
Predictions for next summer? Should have aced temp control by then so will probably be brewing some lighter lagers.
