Lower OG Partial Mash

Good point there M. I wonder what the maximum saturation level is?

@Clint I just know this kind of thing happens from doing Maxi-BIAB but doing a quick google;

"The maximum amount of sugar that will dissolve in a liter of 20 °C water is 2000 grams. A sugar-water solution that contains 1 liter of water and 2000 grams of sugar is said to be saturated."

As this was your first mash, you have no idea what efficiency your method produces: as stated above, Brewmate defaults to 70% but new brewers rarely get that, I got 60% and am now up to 68%. It also varies with malt suppliers/batches, some produce more sugar than others.

I'm also wondering if you had whole grains rather than crushed grains?

I'd suggest doing another brew with the same batch of grain, something really simple like a SMASH, to try to pin down the problem.

This was my second mash, the first time I used 3kg of grain and I got the target OG. I definitely used crushed Maris otter pale malt but this time I used flaked oats and flaked wheat as well
