The idea behind the Hambleton Bard S30 cylinder was to create an economical system for CO2 handling when making your own beer. Before the S30 system, the homebrewer had to use either 8 gram or 16 gram CO2 bulbs which is not a cheap solution for pressurising a homebrew keg. Douglas had the idea to create an exchange system so the homebrewer wouldn't need to pay for the actual cylinder every time, but only for the CO2 he used up.
Around 1978/1979, the first Super 30 (S30) cylinders became available and within a few years this reformed home brewing of beer and made it cheaper and available to everyone. Since the start, nearly one million S30 cylinders have been exchanged.
Today, the Hambleton Bard S30 system is used by virtually every homebrewer when kegging home made beer. Most home brew shops today stock and exchange S30 cylinders and all kegs can be fitted with a genuine S30 valve which works perfectly with the S30 cylinders. If you buy a new barrel, make sure it is fitted with a genuine S30 valve (*).
(*) Hambleton Bard guarantees the function of S30 cylinders with any genuine S30 valve. However if used with a "replica" valve, we cannot guarantee its function. Make sure your keg has a genuine S30 valve (ask your shop if it is a Hambleton Bard S30 valve when you buy the keg). The latest model of valve is clearly marked S30 but there are earlier ones without the trademark. If in any doubt, contact us and we can tell you if it is genuine or not.
