This review is of a dram from my own bottle I've had open about 3 months. The cask mix of batch 19 is 70% bourbon 30% Sherry (Springbank 12 used to originally be much more sherry cask forward).
Nose (neat) quite gingery and biscuity so ginger biscuits, a little medicinal a hint of lime
Palate (neat) some heat on the arrival (which is short). Peat. Which wasn't that noticeable on the nose. Biscuity and spicy.
I had to add water to this twice to tame it but it does have a higher abv than batch 12. The addition of water reduces the heat on the arrival and stretches it out and it becomes quite peppery on the development.
Again not the most complex of drams but pleasing. This batch is a bit more complex than batch 12 with more spice. Compared to batch 12s minerality. They're both unmistakably the same DNA though.
The extra point I would give batch 19 for a bit more complexity compared to batch 12 I feel I should knock off for that heat on the arrival.
