This means winemakers can sell INDIVIDUAL cans in the most popular 250ml size (according to WICresearch’s consumer preference surveys), as well as the most popular size in parts of Europe (UK), which is the 200ml.  It also means wine can be packaged in the 355ml size, which is the traditional 12oz. beer can. 

SUMMARY:

This final rule amends the Alcohol and Tobacco Tax and Trade Bureau (TTB) regulations that govern wine and distilled spirits containers to add seven new standards of fill for wine and distilled spirits. Although TTB had originally proposed to generally eliminate the standards of fill for wine and distilled spirits, TTB is not adopting that proposal at this time. The amendments described in this final rule will provide bottlers with flexibility by allowing the use of the added container sizes, and will facilitate the movement of goods in domestic and international commerce, while also providing consumers broader purchasing options.
