Hi, I am 4 brews in on my Robobrew Brewzilla v3.1.1 and very much enjoying it. However, my first 3 beers suffered both stuck mashes, sparges and low efficiency, but the third was the best of the 3 in terms of hitting the numbers, but still quite low. On my 4th beer I borrowed the top and bottom perforated plates from a friends Grainfather, with the silicone gasket seals and I hit the numbers bang on and had beautifully clear wort go into the FV. Very happy. The GF plates are slightly smaller than the Robobrew ones, so with the seals they fit nice and snug. I'm now considering buying Grainfather plates with the seals as this has had such an impact - does anyone else do this? I've got this paranoia that the Robobrew perforated plates (which come without seals) let water bypass the grain bed and run down the sides and I'll go back to <65% efficiency as before if I brew again. Things I did to help efficiency before GF plates: Stir mash every 20 mins ish, 90 min mash Recirc when mashing in to help break up any doughballs Have tried the trick where you put grain in malt pipe then fill the kettle in reverse through the pump, but preferred the above as it's simpler. Any thoughts would be much appreciated. Thanks!
