Hi all,
I've been noticing in my last few batches of homebrew a weird stale hop aroma, I'm using just about the freshest hops I can find, kept in freezer until needed, and the malt I'm using isn't too old either, it certainly doesn't smell or taste stale.
The only difference to my process/equipment since I started noticing is taking the silicone tube off the end of my recirculation arm. I use an all-in-one brewer and used to have the silicone tube submerged during recirculation, now without it there is some splashing.
For years I've assumed HSA to be somewhat of a myth and not something I've ever worried about... until now. Anyone else noticed a similar issue? I'm now worried when I pick up my grain basket to let it drain into the kettle that I'm introducing too much oxygen too.
Any thoughts?
