Hello folks I just wandered in looking for news about the effects of air on whisky, because I've noticed a marked change in flavor when I get near the bottom of a fifth. It generally takes me two weeks or a bit less to go through a fifth, and during the final three or four days my whisky seems to get more bitter (not sure that's the precise word).

I think I agree with other posters who state that the volume of air can accelerate the flavor changes when there begins to be more air than whisky in the bottle.

I recently changed to buying larger bottles, (1.75 liters), because it's cheaper that way, but I wonder if I need to get back to the fifths, and drink the final few shots quickly to avoid that end stage flavor change.

Do others here have similar experiences, or contrary views to add?

(I will be browsing the rest of this forum...might be a good idea for me to register and hang around!)
