thank you, assuming you are right ( and i think you are ) i have to add the information that after 45 the iodine test was positive.
how is possible that i gain sugar in water also when there is no other sugar to extract?

i've reached the volume target.
The recipe i followed was described for 23 liters, i've used 2/3 of everything for space reason, doing in this way i should have obtained 15 liters with 1050 OG.

one hour boiling.
the Original Gravity was 1044, the final 1010.
i used the amount of malt for a brew with 72% of efficiency (as my recipe considered). At the beginning i didn't know yet how much was my efficiency that's why i obtained such a light gravity.

mmmh i don't think 78% is a truthful value because the recipe i used has been calibrated with 72% of efficiency and they ask for 1050 gravity point. If i use Brewersfriend to calculate the value of efficiency with the original recipe it correspond. In my brew i reached only 1044 so 60% let me unders...

i used 3.4 kg of pale ale malt (2 row), 0.1 kg of crystal malt on 15 liters of final wort; just before inoculate yeast i made the Gravity Measurement and i found that the density of my wort was 1044. Just to simplify my calculus i use this tool http://www.brewersfriend.com/brewhouse-efficiency/ obta...

wow, that's an higher profit that i was expected.
So standing to your data if i keep 90 min. instead of 45 min. i can gain 10% point of efficiency!
can i ask you the ratio between malt and water you used?

Extend Mashing time to gain efficiency

Hi there
I have 60% of efficiency in my BIAB system and for my recipe I'm running 45 minutes of mashing. Assuming that I have the correct temperature and ph, does anyone know how much efficiency I gain (approximately of course) if i keep the mashing time going on till 90 minutes?
