Where are you located? I know many of us got started the same way as you. I think there are a few options for you.
First, visit as many distilleries as you can, and ask questions. Identify yourself accordingly prior to the visit. You'll find that a lot of us, while busy, as excited about the industry and happy to talk about it. Some of us are grouchy though. Just read folks and know when not to push your luck.
Second, read and research. A lot. This forum is fantastic. There are also books and other forums online that will teach you more than you can imagine. Use them.
Third, attend a class or conference (or both). They are not only helpful for the material presented, but for the networking as well. I have met so many great folks from all of the above methods. Get to know them. Personally, as well as professionally. It's easier to ask a friend for help than a stranger. You'll be able to determine who would better address different questions. Some questions might be better suited for TTB folks than distillers, suppliers might better address others.
Last, know when to stop asking. As we both mentioned, small business owners can get super-busy. If you hit up the same person time and again, they may begin to feel taken advantage of. At some point, it is time to stop asking and start doing. You won't get experience without making mistakes. My best advice for those is a squeegee and a hose!
Good luck and hope to meet you on the road!
