I’m losing my head.
It’s not gone unnoticed that several of my recent beers have lacked much in the way of head retention. And it’s not due to lack of condition, as the bottles have been nicely primed and pour with a decent head when serving. The problem is that it dissipates rather quickly and I’m not sure why this should be.
As far as I’m aware, very little has changed in my procedure. I do lubricate my sparging arm from time to time and have swapped to a food grade lubricant, so if anything, I’m presuming this should help matters.
I know I can add adjuncts to assist with the head, but some of these beers are recipes I’ve done before and they’ve been fine previously. Same yeast and all.
My beer glasses are not subjected to the dishwasher either. So what’s killing the head? Could it be cleaning residue in the brewery? Residue in the bottles prior to bottling? If anyone has any bright ideas, please let me know. It’s doing my head in.
