I learned that I routinely do not give my beer enough conditioning time in the fridge. I found a beer that I gave someone that had been sitting in their fridge for a year and 8 months. After I cracked it open (a pale ale), it was crystal clear like a commercial pilsner lager and tasted wonderful. I did not know that level of clarity was possible. I was truly proud of it. From now on, no drinking homebrew until it clears to the same level.
