Thanks to you folks here on the forum I made my frst f-pac for my 3 gal batch of Heritage Red raspberry wine I did following Tom's method. I used 10lbs of raspberries in the recipe so I used 3lbs for my f-pac. I took the juice from these berries, added sugar (no water) and simmered it on the stove for several minutes then added to my finished wine to taste. This wine is MONEY!! The last time I tasted it it was great. It's bulk aging right now to be sure it has finished clearing before I bottle it in another month. This is the best wine I've made to date by far. I even have some of the f-pac left over in the freezer. I'll be using this in a port wine I'm going to do this fall.
My strawberry batch is STILL fermenting (damn, it's been 3 weeks now) but I have fresh berries in the freezer waiting to be used in an f-pac for this wine as well.
