The Manhattan I put in the cask was left for almost three weeks without any attention because I was travelling, I intended to check it after a week but there wasn't an opportunity in the few hours I got to spend at home between trips and this week has been a killer. I'm not convinced on the results of this experiment so far, the punt e mes was probably a little oxidised before it went in and I've ended up with a lot of sweetness, there's certainly a raisin flavour coming in from the rum and it's interesting but the bourbon hasn't really survived the process. I really wish I had some rye to put in there, as I've aged a rye manhattan with good results before, albeit in steel containers and I think it would have come out better here. In hindsight, I could have made a better choice on what to put in after the rum, or thought further ahead to get the right ingredients. I think I'd like to put in something like a white negroni next, with Suze, Gin & Dry Vermouth, but maybe that's another bad decision. The fun is in the experimentation I guess.
