So today I set out to brew my first all grain batch and had everything planned out since thursday. Yeast starter was going great equipment was set up perfect(or so I thought) and all I needed was the grain and aqua and I was set. So everything is going perfect, Im hitting my temps and and then it happens. I mash out 209* per beersmith and wait 10. I open the valve to Vourlof and nothing happens. A slight trickle came out maybe 4-8 oz and it just stopped. I tried stirring I tried googleing my situation in efforts to save this batch and in the end I basically wasted 30$ I inspected my gear and I noticed the false bottom had grain clogging the elbow fittting. now arent these things supposed to keep most grain out of the space in between the dome and bottom of the MLT? What could have caused this? not stirring enough? mashing out to fast? I am pretty irritated but I at least want to come from this learning how not to have this happen again. Any ideas?
