Was that the temp of the water before adding your grain? If so, you should be fine as the grain will lower the temp significantly (based on how many gallons of water/lbs of grain).

If this was the temp post-grain addition, then that is at the high range and you may extract some tannins from your grain bill.

If your mash temp was above 170, you'll get minimal efficiency because the enzymes get denatured at those temperatures fairly quickly. Also, if you didn't buffer your mash pH, you may have extracted tannins at those temperatures.

I forgot to pre-heat my mashtun when I brewed yesterday and overcompensated the strike water temperature, so I was quite high (in the mid-160s) to begin with. Although I managed to get down to my target of 152 within 10 minutes and extended the mash by 15 minutes, I still ended up missing my target gravity slightly. I also forgot to add 5.2 at the beginning of the mash, but thankfully I remembered and added it after a few minutes.

it ended up being in the low 60's for an hour. should i add some corn sugar to compensate?

its for a sweet stout. i planned on adding a 1lb of honey in there in addition to 1lb of lactose in the boil at 30 mins.

If you are going for a sweet stout, dont add hoeny or sugar. That will just dry it out.

thats estimated. i haven't taken a reading yet. i tasted it when i put it in for the 170 sparge, and it didnt taste very sweet. had a more bitter twangy taste. the last batch i made tasted much more sugary at this point, and came out pretty good.

how much corn sugar and honey should I add to get this in the range I want? I haven't taken a hydrometer of it yet, but i will in a little bit.
