Is my mash too low?

[mymbtheduke]

I just brewed my 2nd all grain. I did Death by Dunkel since my basement is about 57 degs. It was harder than I thought to mash 11.65 lbs in 4 gals of water. I preheated the tun then added 4 gals at 165 deg but the mash went down to 147. Since I was at the top of my 5 gal RM tun I couldn't add heated water so I mashed for 70 mins. Then I drained it and added 3 gals at 177 degs but my mash only went up to 160. I let it sit for 10 mins then drained again.

I got almost 6 gals and boiled for 60 mins ending with 4.8 gals at 1.06 OG.

Any thoughts on what will happen to this brew with such a low mash and not really a true sparge? Here is the recipe.

You will get more fermentable wort.
With your temps you should be doing O.K.

So do not worry.

Since it's a Kolsh with a low target FG, I don't think you'll see any difference.

Thanks for the reply but this is a Dunkel with Kolsch yeast. Or are you saying that yeast is yeast?

it will end up being beer. it will taste fine. it's really hard to mess up all grain you have a wide range to mash in. the difference is consistency. that you will get that with time

You might want to bump up the boil time with all that Pils...
