I have some Oak spirals that I soaked for a month in spiced rum and then added to a stout for a "rum barrel" character. After bottling the beer I rinsed the trub off the spirals and returned them to the jar of rum where they've been soaking now for about a year. I plan on making the rum barrel stout again this winter, but after that I don't think I'll make anything with spiced rum again.
Would it be possible to get the rum character out of the spirals so I could use them with whiskey/bourbon or are they pretty much toast? I was thinking I could let them soak in water for a while and then soak them in whiskey, but the spiced rum (Kraken) is very strongly flavored and that might not go away. They aren't terribly expensive so I could buy new ones, but was just curious if I could use them again.
Also, I assume the wood character fades with multiple uses similar to a barrel?
