I seem to have a slight Acetaldehyde problem with a lager like ale (using Nottingham Yeast) in a beer that was in the primary for 10 days then secondary for 20.
Beer was kept at around 18-20 celcius. Never had this problem before. Any way to get rid of it? It's not that bad but it is slight noticable. It's actually probably going to be a quite refreshing beer but not what I wanted form this brew. And I have 10 gallons of it. Kegging five now and will let the other five sit.
I may not be an expert, but I did stay at a Holiday Inn Express........ 6 months ago.
You can find l-cysteine at health food stores. They sell all sorts of amino acids for body builders in cellulose caps... I don't know much you'll need, but if you are looking, health food stores, or online vitamin sources would be starting point.
