Why bother with the drinking glass of Starsan? Couldn't you just pop the airlock out and set it on another sheet of printing paper, considering you trust the sanitation level of the paper? You'd have less chance of infecting your beer then you would using the paper to pour hops. Friction is what pulls little nasties off of surfaces. So the hops slide down the paper, grabbing up tons of critters, and drop right into the beer. The airlock would have only touched one small spot of the paper.
You never know. Maybe a fly or a moth landed on that piece of paper earlier in the day, depositing God knows what on it. Maybe a sneeze from an elderly relative or a child's grubby little hands...
The airlock never actually gets too close to the beer either. Why be so careful with the airlock, but throw caution to the wind when it comes to what's actually coming in contact with the beer? Just seems a bit contradictory to me. In all honesty (and trying to be helpful with this post), both steps are probably not worth the time.
Me? I just wash my hands, sanitize the hop bag and then tear it open, open the fermenter, and toss the hops right in there. Close the fermenter back up and continue on my merry way. Like you, I've never had an infection develop in a years. Ever. Sometimes people overanalyze things. Keep it simple.
I'm not trying to be rude or something with my post. Take most of it in jest! It just appears you're attempt for good sanitation practices with the airlock are great, but then drop the ball when it comes to the step that would be more critical to the outcome of your batch. If you wanted zero/lower risk, I'd recommend buying a small funnel that you could sanitize beforehand. Then your practices would be more in line with each other.
Your chance for an infection are extremely slim at this stage of fermentation though, so again it's probably not really necessary.
I hope you consider this post productive. Thanks for reading!
