The first time I ever drank Sierra Nevada Pale Ale I thought it was the grossest thing ever and didn't know how people drank it. Now that is my standard beer if I am going to a chain grocery store like Publix since they don't really carry any craft beers.
If your store has any pale ales at all or any IPAs you should try a six pack of those. It will be a bit awkward tasting at first as you've never really experienced something with a direct hops-y taste. Where do you live at? Around my house (Cocoa Beach) the nearest craft beer shop is 15min away. When I go there I try and get single 12 oz's of beers I haven't tried before. Some of my favorite types atm are Scottish Ale's, Stouts, and Red's. They all have a smoky-ish, caramel-y taste.
