Efficiency and The Brew Bag - Endosperm is where it's at!

There are some misconceptions in the home beer brewing culture that lead me to write this post. Efficiency is a simple term in brewer's lingo. It means the degree to which the starch in grain, with the help of enzymes, is converted to sugar(s) during the grain mash and transferred into the boil kettle. The explanation of the conversion of starches to fermentable sugars is very complicated and involves PH, water temperature, and enzymatic hydrolysis. I won't go any further on this ( because I don't know much more), but will say that all brewers key in on this term...

Nearly all of them say "but what about all the sugars that get left behind in the grain, aren't you losing valuable fermetables?" At issue is not whether no sparge "loses" fermentable sugar, but how much is actually in the boil kettle. While it is true that the grain bag after lifting from the mash tun has sugars remaining, at what point is sparging a zero return effort? The concept of brew...
