Awesome videos! Thanks fr taking the time to put these up. I noticed your hops in the bag looked a little full or tight. I have noticed when I bag mine up too tight when they swell the wort doesn't move as freely around them all and my utilization is lower.
Great job on the gravity. I thought I heard you mention you were chilling to 21c. If so, by the time you took your sample of wort for the reading, it could have been 70-71 degrees which would have given you one more point to 1.055.
And last but not least....I gotta get me one of those oven mits in the second video!
