Matching a standard of fill
On this page8
What exists at each legal size
475 mL has 110 containers, 945 mL has 59, 355 mL has 54, 250 mL has 21, 100 mL has 19, 200 mL has 15, 500 mL has 12, 50 mL has 8, 710 mL has 7, 750 mL has 3, and 187 mL and 350 mL have 1 each.
475 mL and 945 mL are the unexpected depth
Both authorized, both well stocked, and neither is a size the spirits trade reaches for by habit. They are the metric pint and quart carried into the list.
Why they are deep here and not elsewhere
Because a 16 oz and a 32 oz container are workhorses of every other category this catalog serves. The spirits regulation happens to authorize their metric equivalents, so a general packaging catalog is unexpectedly well matched to two legal sizes.
Which is a real opportunity for a small producer
A 475 mL bottle is lawful, available, visibly different from every 500 mL competitor, and priced against a shelf that is not used to it. That is a differentiator that costs nothing in compliance.
Capacity has to be exact
A standard of fill is a fill, not a bottle size. The container has to reliably hold the stated net contents with appropriate headspace, which is a question about the actual bottle rather than its nominal capacity.
Verify before you commit
Fill a sample to the declared volume and look at where the liquid sits. A container nominally at a legal size that fills to an awkward level is a presentation problem you will live with for the life of the product.
And the thirteen sizes with nothing behind them
3.75 L, 3 L, 2 L, 1.8 L, 1.75 L, 1.5 L, 1 L, 900 mL, 720 mL, 700 mL, 570 mL, 375 mL and 331 mL. Lawful sizes we do not currently hold a container for, which is a sourcing question rather than a closed door.
