This is not a wine bottle shelf, and the pages say so rather than dressing it up.

What is here

328 rows: 145 containers and 183 closures. 124 PET and 21 glass, from 250 to 976 mL with a median of 473.

At an authorized standard of fill

Twenty of the 145. Thirteen at 250 mL, six at 500 mL and one at 750 mL. Everything else on the shelf is a capacity that may not be used for wine.

Which is the honest headline

A packaging catalog is organised around oz and mL sizes that suit food, personal care and household products. Wine is organised around a regulatory list, and the two overlap much less than they appear to.

No cork finish and no crown finish

The necks here are 24-410, 38-400, 28-410, 45-400 and 28-400. Those are packaging threads. A cork finish is a bore specification and a crown is a different geometry again.

And no capsules

The foil or polylaminate over the closure is part of what a wine bottle is, visually and functionally. Nothing on this shelf carries one.

So where does that leave a winemaker

With the sizes, the label rules and the brand name question, which are the parts that do not depend on us. For the bottle itself the right first call is a glass supplier.

Except at 250 mL

Thirteen containers at an authorized size, in a format the category is actively growing into. That is a real answer rather than a consolation, and it is mostly PET.

Which is its own decision

PET has a different oxygen barrier from glass and a shorter practical shelf life for wine. For a single-serve product consumed quickly that can be acceptable; for a wine meant to keep it is not.

What the shelf is genuinely good for in a winery

Samples, bench trials, juice and must, a decant, a wine jelly, a verjus. Those are real needs in a working winery that a packaging catalog serves properly, and they are not the finished bottle.
