Our local craftbrewery has a grapefruit IPA, although I think they achieve their taste through Hops alone. I'll probe the brewers this week when i get my growlers refilled.
BTW it's Sunking Brewery in Indy.
All of the Great Fermentation kits I've brewed up have tasted outstanding. They run a good shop. Currently drinking a batch of their Deck Hand Stout which has been very tasty.
They've got an all grain class coming up.
You don't *need* to make a starter, but it's a little work for a lot of benefit. The smack packs have around 100 billion cells which is a bit on the light side even if they are all viable. Depending on the age it could be less. An average gravity wort can probably take 1.5-2 times that.
