We are also not in the Craft Beer industry we are in the handcrafted wine industry. For many years you had a lot of old timers making wine in the garage or basement. You had Commercial wine company's and a few winery's and vineyards. The old timers would not talk to you about how they made there wine it was a big secret. 

As for beer you had the giants of industry Bud, PBR, and some local beer like hull beer. You drank your beer a pretty much that was it. Now there are thousands of craft beer brewery's thru out the US and the world. 

As a  micro winery we have a wine making facility where clients and their guests can come and their own private label handcrafted wines. We use wine juice kits so we can make wine all year round, not just during harvest. I guest you need to meet your fellow craft beer makers. Entering beer making contest and meeting new people in the industry.Your customers that are really into beer are another way to learn about other Beer Makers in your area they know their names and numbers. 

This is a great marketing tool its a way to break the Ice with other business professionals. Leonardo I hope this helps you in some way. Rick D
