I personally am of the club that believes even Skeeter Pee is better with age. Sure it can be drank at 3-4 months but wait a year and IMHO it's even better... Still have a bottle or two of 2 year old Cranberry Lime around somewhere unless the kids got to them...
I made SP last July. When I bottled it, the SP had a sharp bitter taste. After 7 months, it has smoothed out, and is quite enjoyable.
