Yeah, I was just suggesting that if you're tracking conversion during the mash as Derek describes, as some of us do, it's a heck of a lot easier to take a couple drops, put them on the refractometer stage, and Bob's your uncle, than to pull multiple hydrometer samples, separate the solids, and try to quickly cool them.* Now, should I be returning all those little drops to the mash mixer...? 🤔
*For that, I remember a guy had a very clever solution in last year's gear issue of Zymurgy. Like a little jockey box to pour a sample through.
