Design Features. The function of the glass waker is to make the red wine and air fully mixed. Red wine stored for many years will have an odor, and direct drinking will lose the true taste of red wine. The glass waker uses the principle of fluid engineering to accelerate the flow of red wine by mixing with air, so that the internal pressure of the molecular structure of red wine is released quickly. The tannins in long-term high-pressure storage are rapidly oxidized, while the alcohol is smooth and aromatic. So this is the perfect wine accessory to improve the original value of wine.Use and instructions: 1. Although the capacity of the wine container is 1.2 liters, in order to achieve good oxidation, it is recommended to back up 1 standard bottle, which is 750 ml of wine.2. Cleaning: In order to keep the wine awakener as new as possible, hand washing is recommended, please do not use it in the microwave oven.Specification.Color: ClearCapacity: 1200ml/40ozSize: 38cm highMaterial: high quality crystal glass.Package includes. 1 waker
