Efficiency frustration

Perhaps trying a batch sparge would at least confirm if it's the sparge or not? Dump all your sparge water in, give it a good stir, let it sit for a bit if you care to then drain and see if there's a difference?

Yep Nizmoose I am going to do that exact thing mate thanks . :icon_cheers:

So today i decided to do a brew with 100% RO water.

No minerals were added to the water. Not ideal but the water hasn't been tested so not sure what to add.

Brewing steps and temps were the same as the rest of my brews.
25 min into the mash i had a gravity reading of 1074
60 min into the mash i had a gravity reading of 1079.
L:G 3:1

Going into fermenter i was 2 points lower than predicted and volume was spot on!

Win Win!!!

Next step is to get my RO water tested so i can make the correct mineral additions. My system claims to remove >95% TDS

Only other problem is it takes about 6 hours to filter 50l


Thanks everyone for your input. Problem solved :beerbang:

I thought ro is pretty well just water. I'd imagine you could treat as distilled and make up your water as desired with salts. Should save u the test costs.

Yeah i dont think it would be far off distilled water

If its actually RO water, shes just water treat it as a blank canvas and build whatever modest and versatile water profile you want,whatever you've done it looks like its working well done!
