Thanks for that Andrew,
Interesting, I wonder what the two versions have that throws up that error.
I am going to sparge to the recipe pre boil volume and disregard the BS sparge calculations which seem to be BS anyway.
I wonder if any body that has the Android version and the windows desktop versions finds the same problem.

Unless your scales are out? Any decent water jug should be pretty accurate. Cheap electronic scales on the other hand.

I've found the opposite Ballabrew, and tested on multiple scales, my jug from a science supplier was way out, as are most of my kitchen jugs. Cheers!

Hi Gash
Quick question if I may. I have downloaded your Robobrew v3 equipment and mash profile. I’m an avid viewer of your channel. You help us novice brewers no end so thanks a million for that

My question is also about water volumes. If I download a popular recipe from the BS recipes section, open and apply your settings. The mash in water vols are always a lot higher from what you yourself mash in at. The one I downloaded says to use 24 litres when mashing in which would be at least four litres more than what you would use
Is this just a case of BS calcs being a bit off and it’s probably best to stick the rules you mention above in regards to final volumes
Cheers
Paddy

I cant speak for the recipes you download, but yeah thats way too much water, Beersmith struggles a little with single vessel systems, all of the programs do. All I'd do is double click on the strike water amount and change it to 18-20L, add more if needed. What would be happening is my profile is setup for around the 5kg mark for a 5% beer, so I have the water to grain ratio set to around 4L to the kilo so when you add a big grain bill like 6kg it probably suggests 24L. Which is probably too much for the robobrew, it might fit though I havent tried it.. I suggest for bigger grain amounts to start at the 20L and just see how it goes, add more if needed. Cheers mate!

That makes perfect sense in regards to your grain bill to water ratio
Cheers mate

Will the same concept apply if I wanted to make 20 litre batches

want 20L sparge just over 26 litre mark?

Also if im using your Robobrew profile for 23 litres, and press the scale button on beersmith 3 and scale it down to 20l, will that still follow your profile settings?

Thanks

Yeah thats worth a try, I dont do small batches like that, wouldnt be enough to fill a keg with all the losses, I always brew 3 or 4 litres more than I need so I dont have to stuff around trying to get out every last drop and picking up yeast and hops out of the fermenter. Cheers mate!

Thats what I'd do try the scale recipe, making sure you pick the same equip profile, and just have a go, You might need to tweak things for the next brew and also check mash strike water amount and change it to what you think you'll need. That depends on your grain bill. Cheers

Richie we need to ask questions in a forum post so that Gash gets a heads up. I posted it in social chatter for you. Cheers mate. :)
