By all means go with the 100 proof Herbsaint Original, it is made with whole herbs and is an absinthe substitute, as opposed to a pastis.
The 100 proof Herbsaint Original will work with just about any cocktail recipe that calls for absinthe.

Marion Legendre bottled his own pre-mixed Old Fashioned, back when he owned Legendre & Co.

BTW....The New Herbsaint does indeed taste like the Herbsaint of old, I sampled some at Tales, and it compares very well next to the vintage Herbsaint I have in my collection.

Excuse me, hazelhurst could you contact me via herbsaint@hotmail.com I have a queston from an old post of yours that I'd like to ask you about.

Thanks
