Point taken. The warning may have been overstated as I understand it takes hours for harsher flavors. I was just making the point that when steeping, 30 minutes is fine. WIth mashing, I know about the enzyme activity with the conversion, but I didn't want to confuse steeping and mashing.
"It is sheer folly to be taken by the hand and led down the path of better brewing by someone who says that they know it all. No, it is your experience that counts most. It is your experience that will always lead you to more questions."
