During our first big brew, the grain was slowly added to the mashtun while other club members stirred it in with boat oars! Our super HERMS system was fired up to get the grain to mashout. This worked surprisingly well, increasing that giant mash by about 1 degree every five minutes. From there we started sparging into boil kettle one. Fortunately, when kettle one is full the HLT/boil kettle 2 is empty and we start filling it while we recirculate wort between the two. The 45 gallons (170 L) of HERMS water is used to help finish our sparge.
