(I've searched the forums and can't find any threads about this subject)
I've been going through some of the recipes in the BYO Magazine's "150 Classic Clone Recipes" special edition, looking at the "extract plus grains" versions. I've noticed that the amounts of extract for the recipes I've made or want to make seem to be way too low to achieve the target OG's, according to the calculation resources I always use when preparing ingredient amounts (which have always been very accurate for determining extract required for target OG's).
Some examples of these recipes are below. They're all partial mash:
* Paulaner Hefe-Weizen clone -
1.5 lbs. DME
3.75 lbs. LME, late addition
2.1 lbs. wheat malt
0.9 lbs. pilsner malt
Target OG is 1.053, but the above will yield only about 1.038. I made this recipe per above amounts before confirming this, and measured OG of 1.040. Next day I added 1.5 lbs. more DME and had measured gravity of 1.053.
* Bell's Brewery Two Hearted IPA clone -
4.5 lbs. DME
1.0 lbs. 2-row malt
2.0 lbs. Vienna malt
0.5 lbs. crystal
0.33 lbs. Carapils malt
Target OG is 1.058, but the above should yield only about 1.036. I made this recipe but converted the DME to about 8 lbs. of LME with same amount of grains and had measured OG of 1.060.
* Sierra Nevada Pale Ale clone -
1.8 lbs. DME
4.0 lbs. LME, late addition
1 lb. 6 oz. 2-row pale malt
10 oz. crystal malt
Target OG is 1.052 (Sierra Nevada site says OG is 13 Plato, which is close to BYO recipe's OG), but the above should yield only about 1.040. Have not made this recipe yet.
* Troges Brewing Co. HopBack Amber clone -
7.75 lbs. LME
2.5 lbs. Munich malt
0.25 lbs. crystal malt
1.0 oz. chocolate malt
Target OG is 1.063, but the above should yield only about 1.052. Have not made this recipe yet.
BYO credits the brewers throughout the magazine who directly helped in creating the different recipes. None of the above recipes have these credits.
So, I'm curious if anyone else has seen these inaccuracies in this BYO special clone edition. I've shown these recipes to my local homebrew shop (they're very experienced) and they're just as puzzled as I am. It sure seems odd that these could all be just misprints.
