It will produce a spectacular result that you will never be able to reproduce. Seriously. Soon after me an an old roomie stated brewing, we brewed a Scotch ale that was to be entered into a competition at a local brewpub. The winner was to be brewed on the big system. Our mash schedule went horrobly wrong. Mashed in at around 100, ramped up to over 170, where it sat for about 30 minutes, then crashed back down to 130ish (too much cold) then reheated the mash back to 158. We won the taste competition, but when the brewer reviewed our process, he went with the brew that won second place. Of all the Scotch ales I've made, I insist that this was the best tasting one. And yes, it did have a good start and finish gravity. Can't explain.
