This plastic bottle filler with a spring-tipped valve works best with a bucket or fermenter that has a tap. Simply attach the filler to your tap, insert it into your bottle and depress the dip against the bottle's interior base. Once it's full, lower the bottle to close the valve and remove it from the filler. You will be left with the perfect amount of head space, and are ready to cap.
Using a spring-tipped valve, the Fermenter's Favorites Bottle Filler is an essential tool for a hassle-free bottling day.
