Partial Mash Lager Recipe Please

[SJW]

OK I'm ready to give the ol partial mash a crack. So while it is still cold i want to brew a lager for summer. I'm not fussy when it comes to Lagers as they all taste good. So if someone could post a tryed and true partial mash for a nice summer style lager.
Lagers i like are, Stella, Urquell, Sam Adams, most Belgian style ones. Anything thats not too offensive.

Do you need to add the 1.5kgs of light malt extract to the boil or can i simply dump it into the fermenter. As i dont think i have a pot big enough for 9 litres to start + 2 litres of sparge water + 1.5kgs of LME

 

[Jovial_Monk]

you will only recover 4-5L of the mash water

I recommend towards end of boil taking 2L of wort out the boil, add the LME offheat, stir to mix, dribble back into the boil. I think this is nicer and safer than merely chucking it into the fermenter.

This way the LME is sanitised & dissolved while most of the boil is only the relatively low gravity wort from the minimash meaning hop utilisation is good.

Just wondering how do u control the OG in a partial mash? Am i correct to assume that 3kg's of grain with a 1 hour mash is = to about 1 kg of Liquid Malt Extract?
with only about 50% recovery from the mash then extra sparge water, then evap from the boil + the dregs from the boil with all the hops in , that dont go into the fermenter. This all makes me think that the OG is a bit of a hit or miss affair.

 

[Jovial_Monk]

it is a bit untill you learn the way your system works

a 3Kg mash should give you about an OG of 1030, the 1.5Kg LME will give you about 21 points
