Nose
Citrus and softer gin botanicals lift from the glass.
Palate
This is a useful late Collins checkpoint because it keeps the style explicitly tied to Old Tom gin and a fuller mixed-citrus structure.
Finish
The finish is bright, long, and refreshing.
Summary
A late Old Tom Collins from the mature long-drink branch.
