Two men’s opinions

That's always been a problem with alcohol. Almost needs sealed systems? But that of course is not easily consumer friendly functional.

Brazil apparently has a good system, but in sure they deal with some amount of moisture content.

Not sure how we could do that in the USA when no one wants anything remotely industrial in their neighborhood, no matter the facts.
