... not beer. Trade effluent.
I had to work out our discharge volumes the other day, so that the nice folks at United Utilities could figure out how much to charge us. It's not a complicated sum, but it's quite instructive. Your mileage may vary.
Of the water that comes in, about 15.5% goes in product (beer) or is lost in evaporation, around 2.3% goes out in by-products (spent grain, waste yeast) and 82% goes down the drain.
I know that doesn't add up to 100, but that's rounding error for you.
Or to put it another way - each pint of beer we produce means we need 6.5 pints of water, and gives rise to about 5.3 pints of effluent.
This is actually pretty good for a tiny brewery. And of course, we're not short of water 'round here.
Let's Brew - 1973 Whitbread Mackeson Stout - Still not wrung the last drop from Milk Stout. Yet another Mackeson recipe. But quite a sad one, in a way. Because it’s the last one I have from Chiswell ...
