In my prior attempt, I aged the rum on oak for 1-2 weeks (along with a vanilla bean, cinnamon and cranberries) and it smoothed out amazingly and took all the rough edges off. Everyone who tried it loved it. No complaints.
I've been wondering if that smoothed edge was simply the time or if it was due to the components I put into the rum. My goal has always been to make white rum, but I used those additional elements because I wanted to have a win and I knew that, at minimum, those new flavors would drown any bad flavors

Now, knowing slightly more than last time, I think my latest run produced viable product and I have not added any of the above mentioned items. It's just pure white rum. Its rough, but drinkable.
If aging with the intention of keeping it as a white rum, what is the shortest path to success? Do I need to continue to air it or do I simply place it in a glass container and let it do its thing? How long before the rough edges wear off and I can get some extra esterification? I'm not someone who's trying to let things age for years, at least not at this point in the game. I'm new and I'd like to share my product with my friends and family even if it isn't "perfect".
Also, and somewhat related, I love the taste of it on oak with the cranberries, etc that I added, but I'd also like to strip the color. I've attempted this as I've read in threads by using filtering. This has not stripped any color. Has anyone has success stripping color? If so, what product are you using to do this?
