I figured instead of a review that'll sound like every other review of a first fill sherry bomb, I'd compare the 14 year, the 2020 13 year, and this new 15 year. Why not? OK so a bit of house keeping, the 13 year has had at least 4 different expressions with the most distinctly different being one I didn't get and being all refilled sherry. There are however at least 1 or 2 that use a mix of refill and first fill casks. Here we are using the 2020 which is 100% as springbank calls it "Fresh sherry" or a wet cask. 2017 was refilled and first fill, the 2018 I do not own to check, the 2021 was the all refill and 2019 was the 14 year. Just for the history since 2017 when I became aware, their could be older expressions, but I think that his the complete history. Next up is the abv. For this comp we have the 13 year at 50.3, 14 at 49.3 and the 15 at a higher 54.2. That is not a small increase and it comes with more age! Nose - all 3 expressions bring their own slightly nuanced spin on a rich first fill sherry cask. The 13 year gives off gummy candies and light milk chocolate with a noticeable hint of sulfur. The 14 by contrast is much more staunch with rich oak notes dominating. Still sweet it favors chocolate vs fruits and leathers vs milk chocolate. The 15 finds itself less oaky than the 14 and much more chocolaty than either. It may also be offering up the biggest dose of sherry sulfur. Oddly when not doing these side by side, I wouldn't even think sulfur. Overall, the 15 might be the most inviting as it also seems to give off a nice vanilla bean note, you'll never hear me say this reviewing it by itself. The profile on those is old world sherry, funky oak, light sulfur, and juicy fruit forward sherry that I absolutely adore. With leather notes that would remind me of much older expressions. Taste - Surprisingly they all really do take on their own unique path. The 13 year is this fruity, chewy, lovely red fruit bomb with some sour fruits coming through and giving off this oak and sour note that I rather dig. The 14 is stately as the state with huge oak giving way to book shelves and rich leather with big spices and this overall lovely sweet body. The 15 is however the really unique and different one here. Soft up front giving way to funky and youthful sherry and malt. A bit of funk almost uncooked stewed fruits, with this HUGE bold and powerful finish. The longest finish of the group. A second pull and I get leather and nuts. I've said this before but as I sip this down I get more and more reminders of perhaps even a glendronach 18 year old. I'm sure side by side would leave me laughing at that note as they have huge differences. Overall, 3 very different expressions of a similar whisky when had side by side. When had weeks apart, you'll think they are all pretty similar. Winner in all this? I hate to say it but me! OK but seriously, I think I do like the 15 the best. I like that oak note on the 14 on the finish better. I like the upfront sweetness on the 13 best. But as a full experience, I think the 15 is the one I most enjoy. I could write on for another hour here about the differences but I think this covers it well enough. Final thoughts - I was thinking I might give the 15 a 91 originally, having had the 3 together, I think that was a bit of exuberance on my excitement to even get this bottle. I love this series and I had all but given up hope of landing it this year. Thankfully, that issue was resolved as I found them on the shelf. The new price of 170 for a 15 year, even at a good proof is a bit stiff, but I think the value is there, all be it not the value that it was when these were 130 not so long ago. 4.25 stars, same as the 2020 13 year. Lovely stuff. But if you miss out, I think you've just missed out on a great sherry bomb. Not an epic all time whisky.
