So I mentioned I bought a 2 liter barrel and have run several bourbon projects through it over the past few months with great success. I decided to throw the last 200ml of a cuervo 1800 Blanco in it for a couple weeks and got a nice anejo.
I rinsed the barrel, several times and it still reeks of tequila. I filled it half way with some mixing bourbon for about a month, rotating the barrel every couple of days and every sample I take each week still has a tequila finish. It's not tasty, but not unpleasent, just kinda wierd. I am confident I have ruined the bourbon, no big deal, but have I ruined the barrel?
