Brew day this morning. was a little excited as I want to do two batches today. SO I have my water all heated, Have mash tun all clean, warm it up. Okay all is well. Added grain and water sweet. **** I forgot to put in the bottom screen. Dumped grain and water in clean five gallon tub, put in screen and dumped in the (Now Chiiled) grain and water. Temp down to 148. I was looking for 152 degrees. Drained off about 3/4 gallon and heated on burner, introduced to wort and temp to 150. Live and learn, I hope it turns out.
