Swish barrel is amazing

[850stealth]

So I get barrels from a local distillery and use them for wood working projects. They smell amazing inside. The manager said I could swish them before use. He said to take about 7 to 10 liters of boiling hot water and dump it in and roll the barrel each day and let it rest in a new spot each time. This last barrel was dumped at the distillery and it had an 18 year old single malt in it and before that it was a once used bourbon barrel. I did what he said 3.5 weeks ago and just tested it today. I got 6.5 liters back out at 46% ABV and it is amazing. I went and bought a bottle of what was dumped to compare and its identical. For the price I get the barrels this method is cheaper than making my own. I suggest anyone try it if you have access to freshly dumped barrels.
