I am also a relative newbie, but my favorite is the American Porter. With the American Porter kit, missing the temperature mark has already given you off flavors, but don't despair. I keep mine in the LBK for a minimum of two weeks before I bottle. The off flavors will noticeably subside after 3 weeks. The longer you can wait to let it mellow, the better it will taste. After 3 weeks, my Porter/Stout loving friends have all given thumbs up. To compensate for the higher temperatures, I use a cooler and ice packs to cool things down. Stay with it or the cooler will let the temps really climb.
Just received my Sticky Wicket Oatmeal Stout. I didn't read the recipe instructions thoroughly before ordering and didn't realize the recipe calls for half the grains. No biggie, I'll just order an extra can of St Patrick's Day Stout and smooth LME pack and brew a 4 gallon batch.
I have an English Brown recipe on deck then the oatmeal stout will be next.
