The Eparé Pocket Wine Aerator promises to turn wine into better tasting, more expensive wine. The device enhances the flavor and finish of wine by releasing its natural bouquet. Just push the button, and watch the aerating motor create tiny air bubbles which rapidly introduce oxygen into the wine, freeing its tertiary aroma. It accommodates all styles of wine, with 3 aeration settings, and it's small enough to store in your pocket. (Take it to a restaurant, bar, and even a picnic, too.) Aerate your glass on demand in as little as 15 seconds. The website says you can make a $10 bottle of wine taste like a $30 bottle in as little as 15 seconds.
The Eparé Pocket Wine Aerato has three different settings (White, Red, and Port) which lets the user customize the aerating experience. The aerator measures 6" long, 1" tall and 1 ¼" wide, and weighs just 3 oz. Under $20.
