(NYTimes) - Buy me some pinot and Cracker Jack! Pinot grigio, California merlot, cabernet sauvignon and chardonnay are now sold in sealed single-serve plastic goblets. Next month, Zipz, the company behind this new format, will introduce them at baseball stadiums, including Citi Field (hear that, Mets fans?), and at wine shops.

A couple of entrepreneurs in Miami have also entered the single-serve fray with the Vini, which sells California wines in 187-milliliter (quarter-bottle or quartino) glass vials with screw caps. Bottled in Sonoma, they are far more elegant than the plastic goblets, though you need a straw or a glass for drinking. Zipz claims its varietal wines are “premium,” though “ordinary” is more like it. The Vini calls its blends, mostly zinfandel from Napa and chardonnay from Sonoma, “exceptional,” which is another overstatement: Zipz wines, about $4 each or $14 for a four-pack, will be sold starting in mid-April at Yorkshire Wines and Spirits and zipzwine.com. They will also be sold at Citi Field and other sports venues. The Vini, $35 to $40 for a four-pack, is sold at thevini.com.
