All Grain ---> Extract?

[size]

Okay so I was just reading in Designing Great Beers, about creating your malt bill by deciding proportions and then calculating how many GU of each different grain you need, and converting THAT number into pounds.

So:
I want to do a simple wheat beer, 1.046 gravity, 5.5 gallons which would give me 253 GU's. Assuming a mash efficiency of 68%
50% Wheat Malt ---> 127 GU ---> 4.91 lbs
30% Pale Malt ---> 75.9 GU ---> 3.1 lbs
10% Flaked Wheat ---> 25,3 GU ---> ~1 lb
10% Vienna Malt ---> 25.3 GU ---> ~1 lb

Now I just realized that recipe would be for all grain, and I don't have an all grain set up. So how would I go about converting the Wheat/Pale into dried malt extract? I have the set up for a partial grain, and am starting to contemplate spending the very little money I have towards an all grain set up, but I'd like to know this in case I don't and just to know in the future.

I'm sorry if this is a repeat topic, I'm at work and don't have time to search the forums, and i really want to write this recipe in my down time. Also if you see any problems with the ingredients, let me know.

Thanks in advance for all the help guys! :rockin:

crap, i should know this ratio by heart, its something like 1.3lbs grain-->1lb liquid-->.7lbs dry extract.

You get roughly 37 points from LME and 46 points from DME. You can figure it that way.Wheat extract is a combination of pale malt and wheat malt. The Vienna malt needs to be mashed.Hope this helps.

If you can't get wheat and barley extracts separately you'll also need to know the proportion of wheat to barley in your extract. Since the recipe is about 60% wheat/40% barley you should be able to get a reasonable extract replacement pretty easily. If you want to be exact, calculate the extract needed to replace all of your barley, then figure how much of your wheat malt that extract replaces and add a few ounces of wheat to your Vienna mash to make up the deficit.

Sorry for the bump but I'm wondering if Wheat DME is going to be some Wheat and some Barley? I looked up LME's, and that said the ratio is somewhere around 55% Wheat, 45% Barley. So if that's the case, I'm going to take your advice, Trencher, and compensate the missing Wheat with extra Wheat grain.

Also on an unrelated note how much grain can you typically mash in a 2 gal partial mash?

1 lb grain = .75 lb LME = .6 lb DME...
