I haven’t noticed the price actually corroborate to the amount of glass necessary with anything outside of 750s. Obviously there is more glass needed to make two 375s, but they often sell for more than what I can actually imagine the cost is. Then we get into magnums and I do not see any “discount” (like a case quantity discount if you buy 12 750s on this site), rather a penalty. Glass is not that expensive. I can go buy bottles of cheap pasta sauce in glass for a dollar or so.
I understand the amount of glass needed is some math equation I don’t really want to do to be structurally sound and it gets exponentially more the more volume you put in, e.g. 750, 1.5, 3, 6…
But I generally find anything other than a 750 needs to be something I know and love. Like Scott Harvey magnums or the Vino Noceto splits. Otherwise, eh.
(Would love to be educated by one of the many winemakers who browse these forums on what actual cost vs markup vs selling potential. I am just speaking if all that juice is free flowing, does a magnum really cost $50 dollar premium versus two 750s in egregious cases?)
