Reverse Osmosis Water

Thanks Kadmium, I can't for the life of me see why I would add chalk, other than to increase pH if the mash pH was too low, will try without next time I brew a pomme ale.

On the sparge water pH I typically use 20L+ in a 20L mash as my boil off is usually around 8L. to end with 24 L in the kettle of which 20 L goes in the fermenter so my final runnings can be 1.005, it's not so much about the extract as getting the boil volume I need.

Yep fair enough mate! Give it a try, don't forget you will need less Lactic Acid to drop the PH without the chalk in there.
