Which of those barrels would you use, as well as what would you use them for? All are food grade. The once with two white top lids do not seem to be very air tight, but have a metal clasp. The once without top lids have a plastic clasp. The oval brown/reddish once
are air tight (used to contain olives and jalapenos in oil and vinegar) however, they are oval and bottom is harder to reach.
