I have a neighbor who made raspberry wine for several years. His was a very simple process using cane sugar but that's all I kn0w about it. His raspberry wine was not wonderful but it surprised me that it was as good as it was.
My idea about 15 years ago was to use garden produce for wine making. Strangely, very strangely, the gardeners who I was communicating with and who seemed most happy with their product were making wine from pea pods ..! NOT even the green pea seeds but the leftover shells. I absolutely could not bring myself to even try that!
My best wine out of a half dozen tries, was a simple rice and raisin recipe. However, this was just the sort of thing I hadn't set out to do - I was making wine with ingredients I didn't grow and with grapes. There are hundreds of bottles of grape wine in every supermarket! Most of those wines were as good or better than what I could make with all my limitations. Finally, I used winter squash as an addition to the rice and raisin but to avoid having a cloudy wine, the squash was raw. It imparted a lovely color but that was the only difference from the previous rice and raisin wine I had made - not nearly the big step I was trying for of using garden produce for wine.
Since Dad and I used to make some very good beer ~ about 20 or 30 years ago ~ and I live where both barley and hops are grown commercially ... ah, never mind!
