"The Clean Bottle Express® Wine/Beer DeGasser is a must have for your degassing needs for winemakers and aeration needs for homebrewers. This unique DeGassing tool will help the home winemaker with the hard job of removing unwanted gas out of your wine must. If you are a homebrewer, this tool will easily help with the aerating process by adding oxygen to your beer prior to pitching the yeast. You can visually see the gas bubbles from the wine must or extreme foaming from the beer wort come to life once the DeGasser creates a mini-vortex within your Carboy. No more vigorous stirring with a big Spoon or shaking of your carboys. Let your cordless drill and the Clean Bottle Express Wine/Beer DeGasser do all the work for you."
