Bribie G trots out an old picture once again:
When all grain home brewing started to take off in the 1970s the question was "well, how do they do that in Breweries" and, as per the normal human instinct of copying what works well and then tinkering, most home brewers attempted to build an extremely scaled down version of:
Now we can do that of course, but until modern times it was the only practicable way of making beer on an industrial scale without resorting to something hypothetical like this:
In a way, breweries such as Coopers use almost a BIAB stage using a mash filter where the mash is squeezed in huge bags in a hydraulic press. If they found a way to actually mash in these bags (and if the accountants found there would be a ten cents per litre advantage in doing so they'd be onto it in a flash) then BIAB would have gone industrial.
