Today I had my first brew day brewing all grain. I have been building up a 3 vessel system, all using keggles. I decided for my first all-grain batch I'd brew the Sip of Sunshine clone recipe from July/August Zymurgy magazine.
Keeping temp in the mash tun (152) was difficult. I was trying to continuous spare, but the temp fluctuated too low. I used direct heat to bring the temp up, but overshot by quite a bit. I was at about 162-164 for 5 mins or so. Was able to get the temp down by removing insulation on tun and cover, and going back to the continuous sparge. To make up for the missed temp, I let the mash sit about 5 more mins at 150 before I started lauetring at 168.
On top of this, when I tried to cool my wort to 65, my pump/plate chiller had some sort of malfunction where wort wasnt circulating. I ran inside and grabbed a small immersion wort chiller from my extract days. I didn't have time to clean it thoroughly, but did rinse it off and sprayed it with StarSan prior to putting in the hot wort (about 200 degrees at the time)
My two questions are:
1) How much will not hitting my temp in the mash throw things off? For what its worth, the targeted OG was supposed to be 1.076, but somehow I got it at 1.078.
2) Without a proper cleaning of the wort chiller, do I need to be concerned about possible infection? I did sanitize quickly, but not sure if that will be enough.
