Mash liquor volume question

[kev]

I'm experienced at brewing but new to AG.

How much liquor do you mash with? Is it important? If so, why do only some recipes list that volume?

Think most people work on 2.5lts per KG of grain.

+1 with that :thumb:

I aim for 2.5L/kg too, but go down to a stiffer 2L/kg with higher gravity brews in order to still fit it in the Mash Tun. I perhaps see a slight reduction in efficiency when thats necessary, but it works okay unless I go much below that.

Some people (particularly BIAB brewers) may use the no-sparge method and so mash in all the liquor; the few times i've tried that myself it has worked, though with lower efficiency - but I'm far from expert with no-sparging so that could just be me.

Our resident Pro says the magic figure is 2.3ltrs per kg, I use this ratio sucessfully + 2 ltrs for my "under grain filter" space.

I aim for 3l/Kg . . .sometimes up to 4L/kg . . . although for larger batches I have to drop down to 2.5l/kg . . . . I wouldn't go much below that.

For BIAB . . . aim towards the higher end so 3-3.5L/kg

I don't worry too much about ratios. I got for the same volume for each recipe, irrelevant of the grain bill; 15l.
Then I just sparge until I have the correct pre-boil volume in my kettle, which obviously means a little bit more sparge water for higher gravity beers to compensate for the greater absorption by the extra grain.

It means I'm not faffing around with ratios & volumes, just need to stick my grain weight into BeerSmith to get my strike temp.

That wouldn't work for different brew lengths say 20L, 40L , 60L and 150L

This is very true!!
