Quick question regarding mash efficiency.
I have now done several all grain batches. I use a 5 gallon rubbermaid drink cooler with a false bottom. My first couple batches gave me an efficiency of about 74%.
However, as I have continued to progress I have started to treat my water to try and achieve a water profile closer to the source region of the style I am making. Since starting to treat my water I now consistently get an efficiency of 90 - 91%. This has been the case for several single infusion mashes and even a decoction mash.
I don't want to look a gift horse in the mouth as this certainly lowers my grain bill. However, based on the books I have read discussing the mash process, this is an efficiency that seem to be much higher than I should expect.
Is this anything I should be concerned about? Is it a possible indication of something wrong in the process, say milling the grains to fine?
