Converting a partial mash recipe to all grain.

[Bogwoppit]

I want to convert one of my old partial mash recipes to all grain and am looking for some advice.

The recipe uses a 1.5kg can of the brupaks premium grade pale malt extract, what type and amount of grain would I need to use as a substitute would anyone know?

Thanks in advance.

Depends what beer you're brewing I guess. If its an ale or a stout Id use Marris otter pale malt or the irish pale malt from the recent group buy. As for quantity it depends on what OG you are looking to hit.

The American books usually rate fermentables by their Gravity Units ( GUs)

This is expressed as the wort gravity of (1 gallon) you would get from a 100% efficient mash.

So looking up the bookg


LME:    1.036 / lb 
DME:    1.044

Marris Otter:  1.038


In fact most base malts are about the same.

So to replace 1.5 kgs of LME at 70% efficiency you would need about 2 Kgs of grain

Formula is:


(LME Gravity - ) * 1.5 (kgs of LME )
------------------------------------
(Grain Gravity -1 ) * 0.70 (The efficiency )

That's great, thanks guys.
