quick question - mash thickness
 
qt/lb equals l/kg = TRUE or FALSE?

jkarp 01-26-2010 11:58 AM

Nope.

1 qt / 1 lb is not the same as .95 l / .45 kg.

so what would be the average mash thickness in l/kg that brewers mostly use?

I don't think there really is an "average". It really varies from brewer to brewer and some people change thicknesses batch to batch. I have heard of people mashing as low at .95 l/kg and as high as 1.89 l/kg, perhaps higher. Some people with thinner mashes have been getting better efficiency (because there is more water to extract the sugars), but some people have good success with thick mashes as well. Your mash time also has an effect on your efficiency and how fermentable your wort is.

some European kits suggest mash thickness of 3l/kg. By now I've been using it regularly.

It seems it is really too much water in a mash... But still I had good efficiency... I don't get it. What is the bad side of very thin mash like 3l/kg?

3 l/kg is not that thin a mash. Quarts and liters are almost the same, while 1 kg = 2.25 lbs. So 3 l/kg is not too far from 1.5 qt/lb which is about mid range mash thickness. I mash thin at 2 - 2.5 qt/lb (about 4.5 l/kg)

That is a pretty good estimation.

than what is the right ratio?

doghousechef 01-26-2010 01:18 PM

1l/kg=1.05qt/2.25lb

Isn't it the same, just the other way round?
