The next bottle picked up after Benromach 10. Box came home, got cracked open right away.
What’s different from the 10
The shift from the 10 to the 15 is in the cask finish. Both sit in first-fill bourbon and sherry casks. The 15 then spends roughly six more years married in oloroso sherry casks. The bourbon-to-sherry ratio is reported around 80:20. Peat stays at the same light level as the 10. The cask finish dials sherry intensity up one more notch.
Benromach runs on a handful of people doing the whole production - one of the smallest Speyside operations. Mentioned in the 10 review too. The 15 is that same small-batch run pulled five years further, which puts it on a different shelf from a similarly-priced 15 out of a large distillery.
ABV 43%, no coloring, non-chill filtered, all carried over from the 10. Color is a touch deeper - bright gold with a few drops of soy sauce dropped in. Same family, visible without tasting.
In the glass

Bottle reads the same as the 10 - clean red label, bold BENROMACH wordmark. A good-looking pour. Stared at it for a minute before tipping the glass. Poured straight off opening.
Nose
Light smoke lays down first, then sherry rises pleasantly on top. Not a heavy sherry - a bright one. Apple and pear come in together, apple slightly ahead, and not just any apple - more like a ripe honey apple. A bit of maltiness hovers. Classic single malt Scotch profile, reading like Benromach 10 with the smoke pulled back a notch and the sherry pushed up. Orange honey toward the back.
Palate
Spice hits first. Body fits the 43% well, with a slightly oily texture underneath. The sweetness leans more toward malt than sherry. Not that the sherry sugar is gone - the malt just sits in front by weight. Johnnie Walker Green 15 kept coming to mind. That bottle has its own malt explosion, and the direction Benromach 15’s sweetness takes overlaps. The same read held on the second sip.
Finish
Smoke dominates the finish over sherry, and it’s a pleasant smoke. The label says light peat and it really is light. More smoky than peaty, and it stays around for a long time. Never sharp, never off-putting. Light peat holding its own through the finish like this isn’t common.
After some time in the glass
Sherry’s share creeps up the longer the pour sits. Smoke leads slightly at first, then sherry settles in as the glass opens. The bourbon cask side - vanilla, wood - starts to peek through at the same time. The opening ratio slowly redistributes.
Day one, so the aromatics aren’t fully unpacked. Could land differently after a few days, the way GlenAllachie 15 did post-opening. Might revisit the same glass after a week.
What 5 extra years adds
Rating: 4.5. Light peat held in restraint while first-fill sherry and bourbon balance each other, plus smoke carrying a long, easy finish with zero pushback - those two carried the most weight. The 10’s outline stays intact, pulled one shade deeper.

In the same price tier, Macallan 12 Sherry Oak and GlenAllachie 15 sit nearby on the sherry side. Those run sherry-only. Light peat sitting next to sherry isn’t a common configuration - the bottle ends up less of a head-to-head and more of an alternative without a real substitute.
