Same wort different efficiency

Hi

I was thinking about this and i'm not sure about my idea, so i present you my doubt:


Using different quantities of malt and different efficency lead to same wort (and beer)?
to explain better:

100% maris otter beer

5kg of grain 65% efficiency 20 liter of 1051 wort
3,8kg of grain 85% efficiency 20 liter of 1051 wort

so i've got the same og but i used two different quantity of malt and i'll got different quantites of others compound!

what do you think about?

I also sended this messages to brulosophy.com maybe he can do an experiment if my question isn't insensate and he is interested

The no-sparge folks claim the lower efficiency sparge produces a richer, smoother wort. However, I don't know if that claim has ever been proven in a triangle test. I know the brulosopher does no-sparge (http://brulosophy.com/methods/processes/no-sparge-method/) but I'm not sure if he has done the side-by-side experiment either.

i was thinking about two mash made with the same technic, same initial dilution and different sparge efficiency, no sparge method looks more similar to biab to me!

The efficiency difference between sparge and no-sparge for a 5 kg grain bill is only going to be 8% - 9%. Getting a 20% efficiency difference with only 5 kg would require having different conversion efficiency for the two batches (using different crush size for example), and now you have more than one variable in the experiment. Would be easier to get a 20% efficiency difference with ~9 kg of grain.

great table, thanks!

i used 85% and 65% in the example only to increase the difference of grain quantities and explain better my thought, this summer i think i'm going to make some experiment about this!

Do it at least twice to get a better idea on the results. Get some friend over for a taste test. 3 way blind would be a good idea.:rockin:

yeah i absolutely need some friends also because i'm not a good tester
