Side-by-side of Springbank 12 Cask Strength, batches 19 and 21, courtesy of the generous @ctbeck11 The nose of the 19 stands out as more interesting and appealing to me. Not getting a lot of sherry - seems like I'm getting more of the Springbank funk and peat shining through. The nose on the 21 seems to have a stronger fruit component, along with a floral note, while the peat seems more muted. On the palate, the 19 comes across like an amped up version of the 10-year, which is exactly what I was hoping for in this dram. There's some sherry in there, but it takes a back seat to the delicious Springbank funk and peatiness. The second sip I actually notice more sherry. I'm finding now this has a great balance between the bourbon and sherry casks, but also seems to let the funky peaty spirit show its stuff. The 21 is no slouch, but it's much more fruit forward. The funk and peat are in the backseat on this ride, but this is still quite nice. Added a little water to both. Before, I was strongly favoring the 19, but after I may actually prefer the 21. I'm now noticing how thick and mouth-coating it is. The 19 now seems thinner and a little hotter after adding only a splash to each. So, neat I prefer the 19. With a splash of water I prefer the 21. It's actually pretty tough for me to pick a winner now. I think I may be slightly more drawn to the 19, but honestly I'd be thrilled to have either of these in my cabinet. Scores: Batch 19 - 4.5 Batch 21 - 4.25 Thanks CT for the opportunity to try these. Was really a pleasure.
