I hope craft breweries last for decades. I enjoy trying new breer. I have had some good ones and some not so good ones. I've brewed my own batch a couple times and plan on joining a brew club, although I would be the only woman in the club, so I have been putting it off.
I think as long as there are new brews to try and innovative recipes good breweries will stick around. I recently tried some infused craft brews that were very good; combinations I didn't think I would like were phenomenal. Our local craft brewery is still going strong and actually has expanded twice over the last 3 years. They always have the favorites on tap, a seasonal, and some experimental beer.
Craft breweries will survive as long as a quality product is being produced and the products the customers like, and keep coming back for, remain a staple of the brewery.
