WilliamsWarn invented the worlds first Personal Brewery in 2011 in New Zealand. Beverages naturally carbonate on the first day of fermentation so when the beer or cider is ready after 7 or 4.5 days respectively, there is the option to either consume from the brewery or bottle the carbonated beverage. The counter-pressure bottler was developed for that purpose and it can also be used to bottle carbonated beverages from a Cornelius Keg. The difference between medalling at a brewing competition and no mention at all is often a lack of carbonation fault. The WilliamsWarn bottler is very easy to operate and pressurises the bottle before filling. Speed of filling is controlled by a pressure relief valve on the bottler. Please note CO2 cylinder, Micro-matic regulator and Kegs not included.
