Nose
Scotch grain and lime give a drier, sharper aroma than the brandy or Canadian variants.
Palate
This shows the Rickey template becoming a general long-drink grammar rather than remaining tied to one house spirit.
Finish
The finish is dry, brisk, and citric.
Summary
A Scotch variant from the Rickey family's period of rapid branching.
