@MWJB Sorry it’s on the website info, I was looking at Sainsbury’s still water: “For best before / date: see neck of bottle. Store in a cool dry place away from strong sunlight and odours. Once opened, keep refrigerated and consume within 3 days. Best served chilled.”
How does the number relating to bicarbonate translate?
Table of Nutritional Information
Dry Residue @ 180C 22mg
But it doesn’t say in how much liquid, presumably 100ml, so way above a 50-75mg/l ‘limit’?
Are any of the minerals ‘really’ important?
