Every wine vessel has its drawbacks -- bottles break, boxes can be cumbersome, and a glass of your favorite stuff would force you to inhale an aroma that would make anyone mad, dog. Offering another option: Wine Botas.
Recently imported stateside by a Chi company with ties to the Spaniard whose family's been making them since the 1800s, WB's are traditional wine pouches sometimes referred to in English as wineskins, also the technical term for Albert Haynesworth. The 'tas feature sturdy synthetic resin caps affixed to two pieces of soft tanned leather (sewn together and lined with latex), and come shaped either as a teardrop or a curved kidney bean, so you know what's inside'll warm you up during chili weather. Monotone models're avail in nine colorways (carrot, pistachio, cappuccino...), while flashier options include chessboard squares, zebra stripes, skull & crossbones, and tiny animals from turkeys, to bucks, to boars, which clearly isn't you, since you're running around with a pouch filled with wine, dude!!!
For visual learners, there's a series of diagrams demonstrating proper bota use, including one showing how to "give your friends a squirt shot", something you thought you could avoid by not getting into any night trains.
