Drams, dams and endangered salmon

I read your article about the Stirling Distillery with interest (Green whisky? Scottish distillery tests eco-friendly aluminium bottles, 11 January). The marketing director of the distillery seems to believe that younger consumers could be motivated by promises of far better green credentials from using aluminium bottles rather than glass ones.

However, the production of aluminium at Fort William, in the Highlands of Scotland, is anything but green. The smelter there uses electricity part-generated by the Spey dam, diverted from the Spey catchment.
