Hi, quick question; I picked up a slightly used 15 gallon oak barrel that the owner said was wax (paraffin?) lined. Is this okay to age wine in? I always heard charred or natural oak barrels where best. Also, the guy stored it two-three years ago with some lees left in it that took some doing to get all the dried pieces out. Obviously from sitting the galvanized bands and some staves are loose and will need a good soaking to expand the wood and clean the inside. After all this will it be a good candidate to age wine in? The paraffin liner worries me.....thanks.
