Have you noticed the use by date on the cap? We set it at 3 months, although it can be set at 12 months for water.
That is all fine if you put chlorine in the water which will stop everything from growing – good and bad.
Fresh is best, as Heart Spring water is full of life.
Also we don’t want our bottles out for more than a month or two maximum, otherwise we have to buy lots more bottles which doesn’t help the environment and is not allowed for in our pricing.
