So far I've been lucky, all my mistakes have made something equally tasty to what was intended.My wheat beer has brewed out from 1.040 to 1.008 in 36 hours at 24c. I just added 300g of sugar because my efficiency was only 65%. I've got tons of time. I put in 5.6% of biscuit malt for an experiment and I really think it's become close to the thing I've been trying to do, make a beer that tastes like digestive biscuits. Quite by accident.
