Reading a Chow article about how to find a drinkable wine at the convenience store ... btw, I have yet to see that type of store keep bottles horizantal ... but I digress ... they mention checking for a punt (indentation) on the bottom of the bottle.
How about that? The there's a name to that and it doen't mean less wine in the bottle. So why's it there?
Searching, this old post says
Another clue to the winemaker's intention is the cork and glass used. If your wine was intended for aging, it should have been stoppered with a long (more than 2") cork and the bottle probably has a deep punt (indentation in the bottom for collecting the sediment).

Some of my best luck in finding bargains has been to examine the packaging. A distressed winery will use the same packaging, sans label, it has on hand rather than trying to find small quantities of something else. Look for heavy glass bottles with a punt (the indentation on the bottom), long metallic capsules rather than flimsy plastic, and long corks. These can add more than a buck to the cost of goods and are indications that this wine was made by an upmarket producer and originally intended for a premium market
Interesting ... heavy glass, punt, long corks, metalic capsules.
Any other clues when searching the bargain wine and 99 cent stores that the wine was destined for greatness and not a lowly bargain bin?
Any recent changes due to screw tops and plastic corks, so to speak? Would a wine destined for aging have a screw top ... or a different type? Would it ever use a plastic cork?
