Wine juice in Providence area?
I do not know for sure since we brew beer, but... You should check out the local home brew shops. Our main spot is Blackstone Valley Brewing Supplies. www.blackstonevalleybrewing.com/ in Woonsocket. They sell winemaking supplies. Also, there is Basement Brewhaus off Smith St in Providence www.basementbrewhaus.com, which also sells winemaking supplies. There is also Brew Horizons, I think that is the name, which has multiple locations, one of which is in a hardware store on 44 in Chepachet. apple Valley Hardware I think. They have a website too, if you google it. And finally there is Silver Lake Wine and Brewing supplies, or something like that, in Silver Lake area of PVD. There is a place in Attleboro that I have not been to, and know nothing about. Hope that gets you started. Sorry I don't know for a fact that any of these places have exactly what you need.
