I was at a party recently and was introduced to a fellow homebrewer. As we talked he explained to me that he's not as advanced as his son, who does full 30 day mashes. I said I had never heard of that before, and when he asked how long I mashed I said I have never gone longer than 90 minutes.
My assumption was that he meant something else (fermentation or conditioning) but I didn't want to drill him on it, it was a little awkward. I tried looking on the Google with no luck; has anyone ever heard of this?!
