人気の高まり アルミボトル especially in the beer industry has spawned a collectors’ market for rare aluminum bottles and become a worldwide trend.
Interestingly enough, the rarest and priciest aluminum bottles are unopened. Collectors seem to value aluminum bottles that are in pristine state, with caps intact, no visible dents, etc. It seems they don’t particularly care about consuming the contents. Unlike the wine market, these aluminum bottles are clearly being valued for their packaging and not the contents. Wine collectors buy rare wines with the expectation that they will eventually open the bottles for that special occasion. But it doesn’t seem like there’s much of a market for empty bottles of rare wines.
