This morning I made a mistake while cooling my beer. I first sanitized the cooler (counter flow) during 5 minutes). Then, not to let it on a dirty surface, I dipped the extremity of the pipe in a jug containing sodium percabonate (~4g/liter). I didn't think to close the valve, thus when I...

Generally I use bulk priming after the cold crash. I add the priming solution (boiled and cooled) and let the fermenter in the fridge at about 5°C (41 °F). I wait for one hour before getting the fermenter out of the fridge and beginning my bottling. My thinking is not to stir the beer in order...

It's the first time I encounter such a phenomenon. My beer is good but many foam-like particles sticks to the glass and the empty bottle too. What is this? Why does it occurs?

I plan to build an airlock with a CO2 trap in order to reabsorb the CO2 trapped during a cold crash. I have a clear idea how to do it. My question is: how much CO2 will be reabsorbed by the beer after fermentation during this cold crash? Let's assume we have 20 liters of beer in a 30 liter...

Reading A Homebrewing Perspective on Mash pH. Distilled-Water pH and Buffering Capacity of the grist published by Riffe and Spencer in 2018 I am surprised by the very large dispersion of the results, and above all, by the considerable distance taken by software like Brewer's Friend and...

Hi, I am trying to use the EZ water calculator that seems very easy to use. Nevertheless, there is one point I do not understand very well. It is the quantity of acid that is used to lower the alkalinity with Lactic acid 88%. Suppose I fix the mash water to 10 l. Filling the cell, J37, I can...

Hi, Three days ago, I pitched an IPA (20 liters at 1.058 SG) with a pack of US-05. Nothing happened during 27 hours, then the fermentation started (rather late based on what I am used to). Since the fermentation goes on at a steady slow speed (about 2 SG points / day according to my Float...

Hi everybody, P being the percentage of soluble extract mass vs total wort mass I read that there is a relationship between SG an P SG=((P /(258.6 -(P/258.2) * 227.1)) * 1000) or, expressed less accurately SG=259 /(259 -P) As the definition of specific gravity is density of wort / density of...
