You'll also find that some breweries, like Three Floyds in Indiana, would not sell more beer over a wider area even if it were lawful, because they're already straining against the definition of "microbrewery" and are exploiting product scarcity as part of their product strategy.

This is just another reason why selling beer online is not a great business.

You're very, very lucky. Hopefully you've learned the entire applicable lesson; there are licenses for reselling in addition to limitations on selling some things in some ways.

As has been said, you definitely need to be careful about the legality of your business; more importantly, though, you need to step back and get a much more informed idea of intellectual property and how you can and (mostly) can't use other people's products.

I think (and quite possibly you agree with me) it shows a lot of class on the part of the brewers that you got a phone call from one of their family and not a snotty letter from their lawyers or visit from a tipped-off member of law enforcement.

You would have thought they would own the .com domain for their own trademark! Ask them if they want to buy it to stop others trying it.
