I purchased a new barrel last year, but never got around to filling it with wine. Now, after about 18-24 hours of soaking with cold water, it's still leaking around one of the heads, where the groove meets the head. At what point do you consider it a faulty or leaky barrel? How long should I continue soaking? Should I add SO2 or citric acid, and if so, how much? By the way, this is only a 7 gallon barrel.
Any other suggestions?
