According to Georgina Young Brewing Director for St Austell Brewery and Hare Brewery, they adjust the water for all beers except for Tribute and Propper Job which uses the pure Cornish water. Of course coming from a well it may well have a higher mineral content.

Correct, and when those are brewed at the Hare brewery they adjust to match the St Austell water that they use.
