article: How the craft-beer movement abandoned Jim Koch

[pliny]

Eventually there will be a bubble pop, but I don't see it happening any time soon. True, 3200 micro breweries is alot, but out of those 3200, how many of them are small micro or nano breweries say like Railcar, whom have a very small foot print, beer is in a couple of pubs, or only available directly from the brewery, and only in growlers, ie: no bottling/canning line.

Ken Grossman from Sierra Nevada says the same as you. Plenty of room for breweries:
"Grossman thinks there's room for another 3,000 craft brewers in the country and expects the vast majority will remain small, local evangelists with little distribution."
