About a year and a half ago I purchased a new 10 liter charred oak barrel to put some extra age on some bourbon, mostly for fun to see what happens. I used a 5 to 2 ratio of WT101 and EW black and let it sit for 6 months. turned out great imho. My question is this, I didnt really pay attention until last nite but the barrel looks to have a satin finish of some sort. should that negatively affect the contents? the company sells these for the purpose of storing spirits. any feedback from the vast knowledge base of SB would be greatly appreciated. Randy.
