I found out that I have someone locally who retails wine and beer making supplies. He wanted to try a bottle of valpolicella that I recently bottled from a kit, so I gave him a bottle. He told me that I'm supposed to use the date the fruit was harvested and not the date it was bottled.
He never said if he liked the wine or not, just the fact that the date was wrong. I thought it was fairly rude. I'm more concerned about what's in the bottle, which is great if you ask me.
Seeing as how I'm not a winery and only trying to please my own taste, I think it should be okay to put whatever date I choose. As long as it's relevant to me, that's all that matters. So, my vote is the date it's bottled.
I believe in using local small businesses whenever possible, but in this case George is da man. He's always been polite and helpful.
