The distillery is owned by Diageo. Read 'controversies'. What a stink especially the culling of a herd of roe deer in Fife when relocating their production facilities.
Their HQ is at Park Royal NW 10. I used to work nearby in the 60s and you could smell the Guinness being brewed. The old Guinness brewery has been demolished. https://en.wikipedia.org/wiki/Park_Royal
