Brew In A Bag vs.The Dreaded Stuck Sparge

We read a lot of articles on the brewing process, and lately we came across two that addressed the issue of the dreaded stuck sparge. The sparge is post mash washing of the sugars from the grains and is accomplished by methodically adding just enough water to the mash tun to "float" the top portion of the grain bed. To allow outflow some sort of manifold with approximately 1/16" holes is inserted in the bottom of the tun. This lets gravity and pressure work together to provide an outlet for the heavier sugar laden wort. The manifold is connected to...

So, you're into your brew day, and as usual you think "what if I could transfer ALL the sugars left in the grain to the boil kettle, there's beer waiting to be born!" And then you brew, clean up, have a brew, and realize you made 5 or 10 gallons in 3.5 hours (BIAB), or 6 hours (non BIAB), so you have another brew and forget about it.

Mash - thin or thick?

I wrote this in response to an article written by Brad Smith in which he stated that one of the "cons" to brew in a bag was a high water to grain ratio. He didn't respond.  "You mention that a high WTG ratio produces less beta-amalyse. In my research the higher WTG ratio impacts conversion positively. The enzymatic conversion of starch to maltose for B-Amaylase is activated in the temperature range of 143.6 to 152.6.   See the following from Kai Trauser with references to Dr. Ludwig Narziss and Dennis E. Briggs." The results for mash thickness were somewhat surprising....
