Water of life
Or rather one of the three raw ingredients for whisky, or 'uisge-beatha' in Gaelic. Peat-brown water from a burn (stream). Water is something that Scotland normally has plenty of, and this is the surplus-to-requirements water from Glenrothes distillery on Speyside.
More distillery photos to follow in due course. I can't help it. I grew up in a small Highland village with a distillery round every corner, and worked in one for several years during university vacations. I wish Blogger had an 'aroma' facility, and then you could breathe the whisky-scented air.
