Brew bottler fits directly inside the spout of our white barrel tap and allows you to fill your brew into the bottle with a minimum of oxygen getting into the brew. It also allows you to control the fill level of each bottle easily with no spillage. Simply sterilise with your bottles. Push top end inside the tap spout. Turn the tap on full and allow filler to fill up with brew. Push each sterilised bottle up onto the bottle filler until the inside base of the bottle pushes up against the filler valve and opens it up. Just before the bottle over flows the top drop the bottle down to release the valve. Repeat with next bottle. Please request our free adaptor with your filler if using an English 3/4" tap.
