Having recently finally obtained a reliable means of temperature control, I thought I'd throw down a quick Coopers K&K to see how the system would run. Good news is, it runs like a dream. Holds the temperature within +/- a degree. Unfortunantly the bad news is i chucked in some hops after 7 days and will CC for 5 days. Took a sample after Day 9 and holy shit is it bitter! eye-wateringly so...if thats a word. Now, i have had this problem before and after a few weeks the bitterness has subsided significantly. Umm, and yes i must add that the hops have been sitting in the fridge for over 5 years! So i'm just putting it down to old hops and fingers crossed the bitterness mellows. Be keen to know if anyone else has used hops this old and what was the resulting taste. cheers.
