Thank you both for the feedback! As far as cleaning goes, we circulate PBW throughout our hoses, tanks, and heat exchanger to uproot any solids and then follow with a circulation of sanitizer and hot water before allowing to air dry. I'm unaware of any nooks and crannies where "fun stuff" may begin to cultivate, but will definitely take a deeper dive into looking for that!

Thank you for the response! I start off with 400 gallons of water and add 500 lbs of corn, 150 lbs of red wheat, and 150 lbs of malted barley and begin heating and agitating. At 125°F, I add 1/2 cup of SEBstar HTL and let it work as the temperature rises. Once the mash reaches 190°F, I let it agitate for about 45 minutes before it starts to cool. When it gets down to 170°F, I add 1/2 cup of SEBamyl GL and allow it to work and begin performing starch tests. Once the starch test comes back good, I make sure the PH is 5.5, add 4 cups of Ferm K, and transfer the mash through a heat exchanger to a fermentation tank to cool it to roughly 90°F. Once there, I pitch 1 lb of RedStar Active Dry Distiller's Yeast and set the tank's jacket temperature to 80°F. We are currently seeing 2-3 days of very active fermentation before it just halts completely, with a brix of 6-7.

Hello, I am attempting to mash-in a 400 gallon grain fermentation of corn, malted barley, and wheat. After mashing, it attains a brix of 15 with a PH level of 5.5. We keep the temperature at 80 degrees and fermentation starts off strong, but halts at around 7 brix with a PH of 3.7 after only 2 days. I've attempted to bring the PH back up and reactivate fermentation to no avail. Any advice?
