Cutty Sark is vegan friendly

Company email (April 2013):
"Diatomaceous earth also known as D.E., diatomite, is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder.

Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae. It is used as a filtration aid in the chill filtration process when we make all of our whiskies.
This is made into a paper that the whiskies will then be passed through.

As this material is made from fossilised algae it does affect the vegan whisky consumer.
If a whisky is un-chill filtered then you will have no problems with our whiskies."

Company email:
Thank you for your email and interest in Cutty Sark whisky. It should be pointed out that our knowledge base is on whisky and not medicine so if patients are in any doubt they should consult their doctor / pharmacist / dietician. Cutty sark conforms to the definition of Scotch Whisky and as such, is not permitted to contain any additives, including sugar.

I am not aware of any animal derived ingredients used in our whisky process.
