Converting an extract recipe to all grain

[fermentingnewb]

Good afternoon,

I brewed 3 extract kits which turned out quite well and am wanting to try an all grain batch. I really liked one of the kits by Brewers Best: Mexican Cerveza which had the following ingredients:

FERMENTABLES
6.6 lb. Extra Light
8 oz. Rice Syrup Solids
SPECIALTY GRAINS
4 oz. Carapils
4 oz. Caramel 8L
HOPS
1 oz. Willamette
SPICE PACK
YEAST
1 Sachet

Is it easy as just using the grain to extract chart and use 9 lbs of grain that would equal 6.6 of LME (11.7 lbs of grain if calculating based on 70% efficiency)?

Easy as that. That's what I do when I convert extract to all grain.

Hold on... the Brewhouse efficiency is already built into the calculator:

When I put your 6.6# of LME in Brewer's Friend's Extract to Base Grain Conversion Calculator I get ~9# of Pilsner malt @70% Brewhouse (BH) efficiency:

So using 9 pounds of Pilsner Malt should suffice, according to the above.

70% BH efficiency is actually quite low, 75-80% should be easy to attain. Such as using finely milled grain, a sparge (dunking the bag), and letting trub settle out.
