I had head retention issues with many beers long ago and found out a few things, one being washing your glasses with dish soap. Since then I did a salt scrub on all of my glasses and have even using Star San to clean them.
For the most part everything has worked out fairly well. That is until we talk about my jalapeño ales. The head dissipates quickly. I was asked about cleaning, which I thought was stellar considering I've yet to have a bar hand tell me what they are using.
But today we went to a food truck park and Red Solo cupped it and I saw I kept a minimal amount of retention.
So how do you reset your glasses? I thought and with the time passed....
