size of barrel matters question

[Tōtōchtin]

Hola,
Before I get to tired from spending money on this habit I thought it best to get some storage here before my funtickets dry up. I can get white oak barrels that are new, had wine, had whiskey then tequila. The used ones have been rebuilt with a medium toast. For my corn whiskeys I think 50 liters will work out. I plan on making more rum as I am near a sugarcane mill and planning on doing some trading to help offset this damn expensive hobby. I can get 200 lt barrels for about the the same price as a 20,50,100 lt container. I have read where wine producers use a barrel until they say the wood is dead it does impart any flavors, so I guess that will not work for my whiskey. I figure a small one at 100 lts might work storing my neutrals for gin or just for gin. Curious how it would be for rums.
My main concern if I buy a 200 lt because of the price, will slowly filling it full of rum effect the quality for the worse.
This is a link to what I have been looking at, there are a few wholesalers selling 200 lt barrels as is near me that I also want to check out. They get these from the tequila factories. I have emailed the factories but have not heard back.
I thank you for your time,
T
