The Oilerie in Maple Grove, Minnesota

It's a small shop and you can go in and sample all of their oils and Balsamics before purchasing - they're all in stainless steel tanks with spouts and little paper sampling cups sit next to the tanks. There must have been at least six Balsamics (besides the two I bought, I recall a blackberry and an apple), and about 20 olive oils (evoo, garlic, chili pepper, sun dried tomato, cinnamon, etc). When you want one of the oils/Balsamics, they actually bottle them up for you!
