I am nervously starting the barrel journey with a fresh-dumped, 5 gal barrel from Midwest. Plenty of wine waiting to rotate through and top off, but nervous about ruining good wine instead of making it better. I still have a couple of first timer questions after reading as much as I can find. In addition to rehydrating/swelling the barrel (moreWine! instructions), do I need to clean it and/or sanitize it before filling? Sanitizing - assume I would use this method? Cleaning - now or between wines - since I live in MN, outdoor house is not an option right now. I have a bathtub and a utility sink, but no barrel washer wand (and not sure i am ready for $199 for that). Any recommendations on technique for a small, indoor barrel? Any other "jump in and get started" recommendations for me?
