View Full Version : Oxidation after opening bottle / use of decanter

We all know the character of a given bottle tends to change after it's opened, sometimes for the better, though it's my understanding that the more empty a bottle becomes, the faster the bourbon will oxidize. Is the oxidation process changed at all with the use of a decanter? Are there any particular advantages of using a decanter as far as this goes?

One thing that's nice is this -- I am a big craft beer guy and have amassed lots of rare bottles that cellar and improve very well (gueuze mostly), and the stress of opening a rare lambic bottle is much higher b/c you have to drink the whole bottle right then and there! At least spirits can be savored for many months after the bottle is opened.

Depending on how tight the closure whisky may evaporate a little less from a decanter but oxidation should be the same as it is caused by exposure to air. I wouldn't worry about it either way though, whisky is remarkably stable stuff.

I'd answer Wheat, but I don't want to piss off half the board....:D

Is this issue so controversial?

It's a non-issue so far as I'm concerned.

I'll say this: if it's a whiskey prone to changing over time (read: wheater) then, yes, a decanter may speed up that process depending on the closure.

I use a large, wide decanter, primarily for vatting, since I can get almost two 5ths in it. The closure is pretty tight so it's not a huge thing. Perhaps more important is the large surface area.

Anyway, to answer as directly as I can-- towards the last 25% or so I've been able to tell a marked change (not necessarily bad, though), on more than one occasion. This is over the course of say, two months. I generally try to drain the decanter within a month or two.

Fortunately for me, no bottles around me keep whiskey long enough to witness this effect.
