Though I admit it’s not often that a bottle of wine goes unfinished in my house, I always keep this clever little pump on hand to prolong the life of any bottle that doesn’t get emptied into the glasses of my thirsty friends — there’s nothing sadder than uncorking a bottle of wine a few days after opening to find it’s gone sour from oxidation. This pump, by sucking most of the extra air out of an unfinished bottle, helps prolong the good life of my favorite wines, keeping them still perfectly drinkable for at least a week.
