Witches Hat was started by a young couple that had been laid off the same week when things were going down the tubes here, so they said what can we do to earn a living. Start a Brewery! They said the day they opened, they wondered if anyone would come. When they unlocked the door at noon there were over 50 people in line. IIRC, they exceeded their business plan projections very quickly and had to find more fermentation capacity in a hurry. They are in a strip mall and are landlocked on each side, so they have to move sometime to expand. The place has maybe 40 +/- seats, and is usually packed. They also distribute what they can. Most sales are from the tasting room. They limit growler sales on some beers to keep them on.
It is a combination of good beer, friendly owners and staff, nice atmosphere, all in an area that has the population, but few breweries within a 20-30 minute drive. I have been really happy to see them be successful. They smile a lot when you see them these days.
It it is not without risk but it can be done.
