Vinturi aerator. One red and one white available at time of listing. Very simple and effective little device. I’ve done side-by-side tests with various individuals who stated they could taste a difference between wine straight from the bottle and wine poured through this device — probably wine dependent. I have the ‘travel pouch’ available as well, which I can include when I ship this but I would recommend discarding as the felt on it is disintegrating a bit and is messy and has outlived its usefulness IMO. Marketing Stuff from the company:Breathe life into wines instantly, with or without a decanter. The simple act of pouring wine through the aerator increases pressure as you pour, drawing in and mixing just the right amount of air to help wines open up to their full potential. Without a battery, charcoal, or filter, the Vinturi aerator gives you the same enhanced bouquet, fuller flavor and smoother finish you’d get from 1½ hours of decanting.
