Notes

3 whole fresh grapefruit peels in boil
Same 3 grapefruit a juiced and added at 10 in boil
2 whole fresh grapefruit peels boiled with priming sugar

The whole process took about two hours longer then necessary. There was an unintentional protein rest at 130 degrees for twenty minutes while heating some mash runoff to get the mash up to 150. Assumed the lower efficiency was due to lower mash temp that started at 150 but dropped to 144.
Taste is ok. Lacks grapefruit flavor though it does retain some grapefruit pith bitterness that lingers.
Grapefruit completely disappears after a few weeks in the bottle.
