Never had a stout or porter. What would you suggest some one to try?

They taste similar, and can be a bit rough the first time you have them. Start out with a Guinness Extra Stout, that was my first and I loved the style ever since. If you like the taste of black coffee, you'll love them. Chocolate stouts are good to try too.

Start easy with maybe some coffee or oatmeal stouts, then venture into uncharted territory. The Stone W00tstout is a very interesting brew if you can find it, but it isn't for the amateur dark beer drinker. 13% ABV and the consistency of motor oil.
