I live in the Philippines home of Tanduay rum and since im not a big spirit drinker but i still want to use the barrel for aging and or fermenting. I might plan on buying one of their freshly emptied barrels, is there anything i need to do with the barrel? can i just rack the beer/mead straight into it? do i need to rinse with hot water to remove the boozyness from the barrel? do i still need to sanitize it even thought was freshly emptied? are all spirit barrels the same? because i know that rum is made from molasses then aged and is mixed with sugar and other stuff and then blended to get the right flavor before being bottles and sold. but aren't they all aged in charred oak barrels? how will this affect my beer/mead?
