Mark from Mark's home brew shop in Newcastle, Australia was discussing cereal mashing with me a few months ago when I was down that way. Mark knows every mashing enzyme and what they do (I think there are over 20 of them :? ). He says that if you boil the polenta or rice till it's gelatinised, the ...

thanks guys, never any shortage on sensible answers here. i'm going to test a 2-3 hour polenta mash at 70° prior to the main mash and see how it goes. i'm under a lot of pressure to create some "light" beers. gonna try this with polenta and rice. although i can get flaked rice here in iceland. i'm g...

cereal mashing or not

i've brewed a couple of cap (classic american pilsner) with 75/25 pale and polenta. most likely the most appraised beers i've ever made. dry, but still with a sweet aftertaste, asking for another sip. anyway. i hate cereal mashing and since i cannot get a hold of flaked mais or rice here in iceland,...

during the circulation the heat difference between different spots witin the pot during circulation, is less than 0.2°C. but when i had the pot insulated and just let it sit, the temperature difference was 1-3°C within the pot. for regular biab this is a true overkill :) this is just my hobby. i'm n...

great videos. one the one had I've been thinking about circulating through the mash myself. on the other hand, it's makes the BIAB more complicated than it was ever intended to be. question: don't you loose heat while calculating the mash liquid? i didn't see any heat source compensation. don't kno...

thought i should follow up with some pictures, now that i've finally had the time to set it up: here is the mashing. my amarillo pale was supposed to be mashed at 65-66 (65,5 to be specific) during the circulation, the temperature difference between the middle of the pot and in the side of the pot w...

here is a good article on whirlpooling http://www.homebrewtalk.com/wiki/index.php/Whirlpooling" onclick="window.open(this.href);return false; the whirl pooling has nothing to do with cfc. but it is a great way to achieve both, whirlpool and chilling at the same time. on top of that i manage to do bo...

thanks for the post pistol, your long post justifies a longer explaination from me : i've been evolving my brewing equipment and beers for nearly two years now. i started with a 3 vessel system. 30 liter keg for boiling, 30liter plastic bucket for hlt and an igloo cooler. did my first 36 batches wit...

just a single vessel. get all the pros of biab and herms and rims in a pretty simple apparatus. perhaps the schematic is not that good. the plastic bucket is the fermenter. i will get the whirlpool from the counterflow chiller, so i will end with the fully cooled wirth in the boiler. when i drain th...

i heated up 32 liters. i'm not sure about the time it took, since i just set the controller to 72°C and prepared dinner. i guess it took some 20-30 minutes from 8°C. then i stirred the grain in and closed the lid for 5 minutes, to heat it up. stirred more until the temp was 67°C and then gave it 70 ...

brewing efficiency is a strange beast. since i'm just brewing for myself, i don't bother that much with it. had i been brewing this beer with my old system, i would have gotten 75% brewhouse efficiency (according to beersmith) and 23 liters of 1038 beer to fermenter. in this first BIAB i got 25 lite...

yes, i was very happy with the performance. my brew day was less than 4 hours, grain to fermenter. usually it took me 7 hours with my old system.

next step is to try out the 85 liter pot. p :thumbs:

i finally had my first full BIAB session tonight. i had problems with the chinese 25A SSR's in the first run and ended with just mashing it in the new BIAB pot and using my old one to boil. the pot is a 50 liter ss one, with a 5.5kw heating element. i welded a 1" whaddyacallit to the pot and screwed...

i'm going to brew it like beersmith tells me to do it. i'll just adjust if the result is different.
i have a refractometer so i can adjust the hopping if i'm off OG wise.
i'll keep you posted

thanks, my question was not a very structured one, i give u :) the efficiency dialog, actually displays 3 (in some sense different( calculations. what matters for me is that in my regular all grain brewing with 75% brew house efficiency i would use 5,7kg of grain to get 27 liters into the fermenter....
