OK, tested out my new MLT with 6lbs. of grain. Bulkhead worked great, grain did not clog cpvc manifold, so it worked out. Question is, I did not sparge and stopped brewing process and drained "wort" into a pot to save. Can I use this "LME" tomorrow? I did not check for conversion but it is nice and sweet. I figure if anything got into it, it will be boiled out. I know it sounds crazy but I had something important come up during the one hour mash process. Thanks for replies to an odd question.
