Aging in bottle

Whisky is better studied as the interest and community is greater. There are not that much studies about rum. Since all three distillates are alcohols, I think they behave similarly. Everyone can believe what he want. Ultimately, we won't notice the changes I think.

vomi1011: I prefer the second article which says that most people cannot detect the very subtle changes that may occur inside a closed bottle. The first article mentioned a lot of Godawful flavors resulting and not something that is desirable in bottle aging. It also brought up how vodka can lose it's flavor through glass leaching. Neither article mentioned rum, but both mentioned scotch whisky. And screw caps are actually safer! Surprise, surprise! No wonder Richard Seale uses a lot of screw caps in his ECS rums.

There are different opinions. Accordings to some articles that I have read I would say yes, but not much. One reason is the bottle shock, the contact of the liquid with oxygen during the bottling process and the other one are the materials that are not completely tight. http://whiskyscience.blogspot.com/2013/02/bottle-maturation-obe.html https://whiskymag.com/story/bottle-ageingso-wheres-the-science

lucle5: Spirits do not change flavor in the bottle unless opened. None of them age once bottled. The only aging occurs from the wooden barrels. Since HC7 is a dry rum, it should also last quite a few months after opening. I tasted that rum once and cannot even get any from Cuba due to the embargo from the USA. Consider yourself lucky to have it!
