Equipment used: Grainfather Strike volume: 17.13 Liters, sparge volume: 11.91 Liters as per calculator. Will be about 17L and 12L in reality. This recipe was intended as a Belgian Dubbel. It meets all requirements according to the style guide except it should be darker. It ended up being more like a quadrupel, but is a little light in ABV (which turns out to be 8%). Hence the name "Quadubbel". :-)
