Starting a new 5 gal or so batch with 22 lbs of frozen raspberries with a hint of strawberry - about 4 lbs also frozen and from my backyard patch. It will be nice to get some room back in our freezer.
There are many different types of raspberries. We grow 2 types. Our wine is a mixture of both kinds and 4-5# is plenty for us. It really depends on the year too.
