Why are wine bottles the size they are?
As a guy in the business of wine sales and support, I have to admit I'm kind of disappointed in myself for not knowing the answer to this question. I've given thousands of winery tours, for tens of thousands of people, and I honestly don't remember anyone ever having asked me that specific question. Haarumph! So I'll make a few guesses: 25.4 ounces is the perfect amount of wine for a couple who want a buzz but don't want to get too lit up during an evening together; 750mL is about four glasses of wine so it's the perfect amount for two pairs to get a glass each - enough to enliven the conversation but without so much that they say something untoward about swinging; four or five glasses of wine is just the right volume to feed to that gal you're trying to loosen up on that all-important third date while you're swigging the last bottle from your half case of beer to induce her to leave her panties in her purse after all that liquid has sent her to the bathroom again(friggin' panties suck); a fifth of vino is juuuust right to bring to a dinner party when you don't know what to bring because you can't cook, and also can't show up with a can of pringles....again.
The size of the standard wine bottle is almost exactly one fifth of a gallon, but as to why that is the case, I can only make silly jokes about that. I hope to learn the answer, and will not look it up as per instructions.
What was done was to take the old standard sizes and make comprisable metric sizes to reflect the standards of much of the world. We Americans don't use metrics for the most part, Imperial all the way.
It has nothing to do with imperial versus metric
Will you provide the answer suspense is killing
Glass wine bottles used to be hand crafted by glass blowers. The volume of the bottle was the average amount of air a man could exhale
when blowing the bottles. It became standardized just like an acre is defined by what a pair of oxen can plow in a day.
