I was reading the Artisan Spirit magazine the other day and the article written by Wilderness Trail Distillery on cranking out the maximum number of barrels on your equipment got me thinking about their mashing technique. Is there a reason to add smaller grains (rye, wheat) after gelatinizing the corn, instead of adding it at the same time. The whole article is on minimizing the cook time and overall efficiency, and I don't know what the downside of adding rye and wheat at the same temperature step as the corn would be...thoughts? Some off flavor I don't know about?
I have done a few mashes with the corn and wheat/rye added at the same time and brought to 190; I have never really seen any problem with this but perhaps if I dropped temp to 170 to add rye/wheat the flavor would change.
