I've recently been tasked with upgrading some of our methods of measuring gravity at the distillery I work at. My background is in beer so I'm used to running off clear wort for my refractometer or hydrometers to measure. I'm also familiar with ways of filtering/degassing samples of fermenting wort for taking accurate measurements throughout fermentation. Here's my issue though: mash is thick! I've tried pouring it through a coffee filter, sieve, filter paper, and even cold crashing samples to get clear wort. Some of those methods worked well, but took way too long for our pace, or didn't remove nearly enough solids.
I'm going to be using temperature correcting hydrometers (deg. Plato). I'm thinking a french press might be the way to go. Has anyone tried this? I considered using a vacuum flask to pull my samples through filter paper but I'm trying to keep my cost low and the method fairly simple so it doesn't throw a wrench into our workflow (and so the other brewers actually do it). I've also considered using a centrifuge but the one we have for our lab samples is way too small for the sample size I need.
Any advice would be helpful!
