Working out water to grain to hops ratio

[salnajjar]

I'm having some serious problems with trying to get the right water to grain/hops ratio.

On this brew I used 13 litres for mashing with a 6.87Kg grain bill, I sparged with 19 litres of water. I only ended up with 13 litres going into the fermenter. Is there a calculator to work out how to get the right output amount of liquor? I know I would need to increase my grain bill to still hit the right gravity but some rough ratios would help a bunch.

Thanks

it doesn't seem possible you only got 13 litres from 32 litres, that mean you somehow lost 19 litres of liquid. You lost almost 7 to grain but that still leaves 12 litres unaccounted for, assuming 1 litre dead space in your mash tun and maybe 3 lost to hops that leaves 8 litres missing, you might lose 3 during the boil so you are now 5 short. Anyway I assume you are batch sparging, here is Daab's Batch Sparge Calculator
