Nose
Lemon, lime, and rye rise together sharply.
Palate
This matters because it shows the sour family taking on more charged-water and split-citrus complexity without yet becoming a fizz or Collins.
Finish
The finish is tart, lively, and faintly sparkling.
Summary
A split-citrus rye sour on the edge of the charged-water branch.
