Rutger Knoop, polymer researcher at Food & Biobased Research
‘Having fun with yeast and hops'
His wife gave him a home-brewing kit five years ago. ‘The orange squash method', recalls Rutger. But the start of a hobby. It's all done at home in the kitchen, in batches of 20 litres, all stirred himself. He experiments with his own yeast and - from next year -with hops from his own garden. ‘And everything in line with the Reinheidsgebot: nothing but hops, yeast, water and malt.' He drinks very little himself. ‘I brew more than I drink. If stocks get too big I throw a party.'
