Similarly one may ask, how do you use a hydrometer for mash?
Fill your hydrometer tube about 2/3 of an inch from the top with the wash/mash you wish to test. Insert the hydrometer slowly not allowing it to drop. Give the hydrometer a light spin, to remove the air bubbles that may have formed. Read where the surface of the liquid cuts the scale of the hydrometer.
One may also ask, should you stir mash while fermenting? Stir the Mash
If you can manage it, you should always stir your mash at least a few times during the saccharification rest. On a homebrew scale, stirring your mash involves opening up the mash tun, and exposing the mash to cooler environmental temperatures.
Beside this, can you use a beer and wine hydrometer for moonshine?
Equipment Needed to Use a Hydrometer
Beer / Wine Hydrometer- You can't use a spirit/Proof & Tralle Hydrometer for mash making. Hydrometer Test Jar- You can use plastic or glass for the mash- only use glass when you are distilling as the plastic could crack.
Can moonshine mash ferment too long?
As long as you keep it airlocked (or nearly) you can put it off indefinitely. I mean wine may be left in carboys for even a year sometimes and it doesn't hurt it. A few days wont hurt your mash. oxygen in you fermentation containers, this could cause it to vinegar (if you're using fruits).
