The dispensing spear turns your standard DFI Growler into a draft pouring vessel capable of dispensing all manner of beverages through the tap, there are three parts to the tapping spear, the "spear part", "the faucet" and "regulator". It fits on all DFI growlers and affords the drinker the “straight from the tap” drinking experience that can be taken on the go. Straight from the tap is often a preferred drinking experience compared to beer from a can or bottle. The converted Growler can be used to dispense your favourite craft beer, wine, cider, orange, fizzy or even used to make your own soda water simply by adding water, charging with C02 and shaking which produces sofa water. C02 cartridges are not included but these are sold separately.
