Hey fellow brewers I was just wondering if any of you guys owns one of these flash new grainfather glycol fermenter chillers and if they are worth the Cost? They sell for around $1400 Aus not including the fermenter which is another $700 on top? Iv done a bit of reading up on these things and apparently they can cold crash and lager down to 4c? I lager in my old chest freezer at 1 to 2c and that's always worked well but 4 would be a little high I'd habe thought? Anyway guys thought and reviews on these things let hear it?
