Doglover. Maybe you could google garlic festivals and see if there might be one close enough for you to go to. That might be a way to taste some different varieties?
You may want to grow some varieties that are better storing than others as well as for flavor. You can start off with just a couple of varieties and make sure you save some for planting the following year and add one more variety each year, saving some from each, each year. Or eliminating some each year. It just takes a little bit of time to know which ones you'll want to grow.
