Oasis RO3 Water Profile

[getack Senior Member Find all posts View Profile Close getack]

Good morning all

I have some pretty nasty tap water (acidic!) so I want to buy some of Oasis' RO3 water to brew with. I've heard some good noises about this.

Does anyone have a water profile for it? I want to enter it into Brewer's Friend so that I can be sure all calculations and and notes and things are done properly for my next brew.

Many thanks!

I know the CEO so will try to get hold of him this week. I also use their water but add a teaspoon of gypsum and a teaspoon of Calcium chloride with each brew.

RO water can be considered as distilled water. The left over minerals should be in single digits. So it shouldn't skew your mineral additions out of range.

Thanks for this

I only realised this morning that I can probably just buy a bottle in the store and check the mineral contents listed on the label...

Anyway, the near-distilledness is a good thing for me. My tap water is really acidic - I borrowed an aluminium stock pot from my mother for a brew I'm planning and the damn thing turned black inside after a test boil!

So hopefully with a neutral supply of water I can actually determine if I can make delicious beer or not!

Mine did exactly the same, it is an oxidisation coating if you boil only water in any alu pot. Leave it in there and continue to boil your beer in it, that coating will stick and not steep into your brew.

Where did you buy calcium chloride??? I've been googling and driving everywhere but can't seem to find it ...

Apparently Calcium chloride is available form petshops that focus on fish and swimming pool shops. or from this place: Merck Chemicals
