So I've spent the last while working on all things coldbrew, everything from brew times, temperature, bottles vs tap water, Co2/nitrogen, pressure is next on the list along with a few other things... the list goes on. Anyway I was emptying a keg of 3 day nitro brew and decided to bottle some, put it in the fridge and forgot abt it for a day...actually 3 days. I wasn't expecting any of the nitrogen/bubbles to hang around but I did get a bit of a surprise. I went to pour a glass and found a load of particles suspended in the brew. Thought it was coffee grinds at first but soon realised it was the oil/fats from the coffee, and there was a lot. I've emptied kegs with 10 day nitrobrew and found no oils so I'm assuming it's got something to do with the degassing of the brew!This hasn't happened before with my regular cold brew so I'm guessing that the nitrogen/Co2 gas is responsible.
I'm pretty sure the more I think about it the more questions I'm gonna have,just can't think of any at the moment:)
