I have some experience using walnuts for cordials and I currently have a batch of nocino in process (it's been "infusing" for about a month and a half). First, you may find significant differences between a nocino made with Persian (English) walnuts as compared with black walnuts. A couple of years ago I made batches of cordials/liqueurs with both for comparison. The black walnuts, not surprisingly, produced a more intense flavor. Most people who tasted both liked the black walnut better than the Persian walnut cordials. I suspect the same would be true for nocino, at least I suspect you'll taste some significant differences. I am working with a friend of mine to test this somewhat informally. He made a batch of nocino last year with black walnuts. Currently, it is drinkable, but as with many such drinks, it will get better with age. Earlier this year, I found a source for Persian walnuts in CA and ordered 5lbs. I gave him half and kept half for myself. We both made batches with these. Eventually, we'll be able to see how the two types of walnuts compare in nocino (the batches will have different start dates, which offends my scientific sensibilities, but I did say it was an informal test) ;-) My source for the Persian walnuts takes the time each year to harvest green walnuts for folks who want to make nocino or green walnut relish. The ones I got from them were perfect in terms of their stage of un-ripeness! They were not inexpensive. In my research on nocino in the scientific literature, I found a couple of studies published in food science journals that tested nocino for things such as antioxident properties. In one of the studies (maybe both - I don't have them handy right now), they also tested the effects of harvesting time. In part, this is due to the "legend" that the walnuts should be harvested on a particular day. I will be happy to report back our findings, but it will be a while! ;-) Eynon Eynon Langenydd [log in to unmask] [log in to unmask]
