The Winemaker's shop is a great place to purchase winemaking or beer brewing supplies, and they've got kits and ingredients to make root beer and ginger beer if you'd like to try making a carbonated dry beverage. They carry a nice selection of hops and malted/unmalted barley, yeasts, and they give really good advice. For winemakers they carry a nice selection of yeasts, and you can choose between growing your own grapes, or using their juice (may be concentrate, I don't remember).
For the beginner they have everything you need from carboys to bottles...and lots of great books and advice. The owner is often there, and she is very helpful and has years of experience. This is her passion and it shows. I've never found a better place for knowledge or selection in Ohio.
