Yes so far just single infusions. This makes me think that I need to invest in some iodine and steal some of my kids sidewalk calk!?!

I recently just did a 40 minute mash and got 82%, I BIAB. This got me wondering just how low of a mash time I could go, I'm totally trying a 20 minute mash next time!

I dropped my boil to 30 minutes on that run and was fully put away and cleaned everything just before the 3 hour mark. And with more hop bursting, you could get that boil down WAY far...like 15 minutes probably for low IBU beers.

Could under 2 hours be possible for a full all grain? Oh baby!

I'd be careful dropping boil times, you want to make sure you kill the bad guys and what about hot break, there's some important chemistry happening in them thar boil.
20 minute mashes make more sense, if you hit your percentages then it's long enough. I prefer to take my time but I have a HERMS setup.

I have been wondering the same thing. I just got a refractometer and it's interesting to take readings during the mash. I have noticed I don't really get any more conversion, based on SG, after about 30-35 minutes. I still do 60 minute mashes but I am starting to wonder why?

I've had great conversions on many 30 minute mash's. If I'm doing double batches I iodine test and dump the first as soon as I feel good. With great results.

As far as shortening the boil, this is a whole different story. I've done a couple 45 minute boils on beers and they were fine. Just adjust for the utilization of hops and make sure it is rolling good. But I have limited experience there.

I am intrigued by this as well. I am curious what kind of ratio of grain to water you used for this. Could it impact the overall effectiveness of shortened mash times?
