Here is my question. Once you have decanted a bottle of red wine, how long is the wine IN the decanter good for. Is it good longer then it would be if I poured myself a glass and then re-corked the bottle ???? Or is it better to decant the entire bottle even if you don't plan to polish off the entire bottle in that one sitting.
I have noticed that the bottle I have had in the decanter since last night has alot more tannin in it, or so it seems, since last night roughly an hour or so after decanting. How is this so ?
Thanks in advance.
