After some threads and thinking about HSA, aeration and oxidation I decided to perform a couple experiments.
One was unintentional...the porter that I brewed and let splash during sparging into my kettle to snap a pic that some folks cautioned would/could suffer from HSA. That was mid July. When I was bottling my Belgian Golden Strong ale and decided to intentionally aerate 4 bottles. Two got a special mark on the cap. This was bottled the weekend after the porter was brewed.
I just opened one of the marked bottles. Holy carbonation! This brew is over carb'd by design but this example was just insane with a massive fluffy bubble ridden foam. Taste? CRAPTASTIC! The nasty cardboardy flavor was immediately noticeable and made the beer unpleasant and IMHO undrinkable.
OTOH, I have been drinking the porter over the past few months with zero noticeable off-flavors or negative effects to date. I have one in the fridge chilling right now for next up.
.....Ryan_pa: Your bottles are going out this week and I apologize in advance if you get one of the unmarked experiments
