My first beer was an all malt porter kit from True Brew. For my second batch I want to brew Jamil's Robust Porter. The extract recipe looked like this:
6.6 lbs Pale LME
1 lb Munich LME
1.25 lbs Crystal 40 steeped
0.4 lb Black Patent steeped
0.6 lb Chocolate steeped
1.5 oz Kent Goldings @60
0.75 oz Kent Goldings @knockout
For partial mash could I just do it like this:
3.5 lb Pilzner
1.25 lb Munich
1.25 lbs Crystal 40
0.4 lb Black Patent
0.6 lb Chocolate
That's 7 pounds of grain for the mash. 10 quarts gives me ~1.5 qt/gal. Then I'd just add the remaining four lbs of LME at knockout and be good? [s]I'm swapping extract and grain at 1:1, and I don't think that works.[/s] I've been digging through my Palmer book but can't find the info on converting from extract to grain.
Sorry for the wall of text. Thanks!
-EDIT- I just bought two cheapo stainless 4gal stockpots for this method (previous put was 2.5gal) so I was trying to keep the size of my mash down. Did I under shoot at nine quarts?
Your specialty grains should always go in the mash. For them, it replaces steeping. You'll want to have enough diastatic power
to convert everything, so put pale malt in there. How much after that is up to you and your capacity.
Pilsner Malt is not the same as Pale Malt.
With your specialty grains, you have 2.25 lbs of the dark stuff. Also, I don't know if you are going to find 1lb of Munich LME. LME is difficult to measure. I noticed you adjusted your Munich Malt down from 1.33 lbs. This seems OK. Most of the color and flavors are coming from the roasted grains.
At this point, you have 4 lbs to be mashed and a diastatic power of about 17. If you add 1 lb of Pale 2-Row Malt, you'll have a power of about 40, which is what you want.
You probably shouldn't add 5 lbs of Pale Malt to it. If you're really concerned with hitting your OG, you could leave 3.3lb of the Pale Extract as LME and buy 3lbs of Pale DME. You could easily mash a total of 6 lbs and you might not have a problem with 7. So, go ahead and throw a total of 3 lbs of Pale 2-Row in there.
You'll need to add 1.2 lb DME.
As you near the end of the boil, you could measure the specific gravity. If it's too low, add some DME to bring it to where you want it.
DME gives about 44 points per pound per gallon. In a 5 gallon batch, 1.8 oz DME will increase your gravity by .001.
