Better Brother Brewing's N/A Raspberry Lime Kettle Sour is an award-winning alcohol-free beer from the brewery in Saskatoon, Saskatchewan. It was the brewery's first alcohol-free version of this style, which is made by souring the wort in the brew kettle before it is boiled, giving the beer a sour edge. It is flavoured with raspberry and lime, with the raspberry coming through strongly. The recipe also adds B vitamins.
