Story so far: Kolsch - mashed at 68.5 - 70 degrees C for about an hour - recirc 40 minutes temp of grain bed went up to about 75 then one hour sparge - sparge water 78 or so. Boil one hour. Final runnings on the sparge 1013.
My gravity reading prior to ferment was 1051 (the aim was for 1053) Fermenter went in the fridge at around 18 - 19 degrees
after 7 days I racked the beer and got a hydrometer reading of 1020, my refractometer reading was 7.1 brix (1027ish) when this is corrected in beersmith 2 it says the reading corrected is 1014
My fg aim is 1014
Beer went back in the feerment fridge at around18 degrees for another 5 days. I took a reading today and got 1021 on my hydrometer and 7.1 brix on the refractometer so there has been no change since I racked the beer.
I have always used my hydrometer so I am perplexed as to why the beer is still sitting on 1020 unless the mash was too high etc btw I used two packs of liquid kolsch yeast.
I am also perplexed as to why there is a .006 diference in the readings between the corrected refrac and the hydro?? I have calibrated both - the hydro is calibrated for 20 degrees c
Any help would be appreciated
