I would say with a summer ale with additions such as basil and lemon zest you want a very little amount of hops. I'm thinking less than 25 IBUs. the amount of attenuation is up to you. I could see this summer ale good either sweet or dry so it's up to you and what you want. if it is sweet make sure you add plenty of basil and lemon to get those flavors to balance.
Ah, sorry I omitted a small but critical number. FG is 1.015, not 1.05... I've taken all advice and I think I have a final recipe that I'm going to run with. The FG ended up a point higher at 1.016 but I think it will all balance. Unless Anyone can see any glaring errors I'm going to plan to brew this in the next 2 weeks. Thanks everyone for the input, very educating for me!
