Just curious what people's experience has been. I started oxygenating my wort before adding the yeast because prior to that, my fermentation was pretty inconsistent and short (1-4 days). Now that I'm oxygenating, my wort is fermentating 6-10 days. Talking to the guy at Harpoon Brewery, he mentioned 5 days is optimal. Should I be worried about the excessive fermentation?
