I have the same problem. In my case its the yeast. I wash my yeast and try ro get the most out of it. Pretty much after 3 months in the fridge without using it is about the life of my yeast before things go sour. I have been sticking to SO5 for now and no sour beers this far.[emoji2]Just pulled a glass off the keg - and again I have a sour flavor. That brew day I did a 5gal batch of a Grants Perfect Porter that also has a sour flavor..... Guess I need to look into my process and clean the heck out of everything for the next brew day...
One question - How long do grains keep? I work off a 50lb bag that lasts me 12-18 months and Im wondering if the grains could be causing some of this..??? could be grasping at straws too.
I did primary in glass with a foil wrap cover for 4 weeks - perhaps that allowed an ick into the batches.
I do wash all the equipment before i put it away and before use with diligent rinses to be sure there isn't residual soaps. I also use starsan and am extra cautious.... Thoughts welcome
