There is a particular pleasure in a bottle that asks you to do a little detective work. Berry Bros & Rudd — London's oldest wine and spirit merchant, trading since 1698 from their gloriously creaky premises on St James's Street — have long played the independent bottling game with a quiet, knowing confidence. Their "Williamson" bottlings are filed under the open secret category: an undisclosed Islay distillery whose identity most whisky drinkers will piece together after a single nosing. I'm not here to spoil the puzzle. I'm here to tell you whether cask #213 is worth your £89.50.
What I can tell you is this: we're dealing with eleven years of Islay spirit — distilled in 2013, when the island's distilleries were running full tilt into a global demand surge — finished in an oloroso sherry cask and bottled at a commanding 59.8% ABV. No chill filtration, no colour added. Berry Bros don't tend to fuss with their single casks, and that restraint is precisely the point. You're getting the liquid as the warehouse intended it.
The marriage of heavy Islay peat and oloroso sherry is one of whisky's great double acts. At its best, it produces something that feels almost paradoxical: smoke and sweetness locked in a slow dance, neither partner leading for long. The oloroso influence at eleven years should bring dried fruit weight — think fig, raisin, dark chocolate — while the coastal peat character provides that briny, medicinal backbone that Islay loyalists chase from bottle to bottle. At cask strength, this is not a whisky that will meet you halfway. It demands your attention and rewards your patience.
Tasting Notes
No formal tasting notes are provided here — this is a bottle best discovered on your own terms. What I will say is that the combination of a 2013 Islay vintage, over a decade of maturation, and a quality oloroso cask from a bottler with Berry Bros' track record sets the stage for something genuinely interesting. The cask strength bottling means you can dial in exactly the experience you want, one drop of water at a time.
The Verdict
At £89.50 for an eleven-year-old cask strength single cask from a respected independent bottler, this sits in a sweet spot that's increasingly hard to find. The Islay independent bottling market has crept steadily upward in recent years, with comparable single casks from other houses routinely clearing £100-£120. Berry Bros have priced this fairly, and cask #213's combination of age, strength, and sherry cask influence makes it a compelling proposition. A 7.9 feels right — this is a confident, well-constructed bottling from a merchant who knows exactly what they're doing, even if they won't quite tell you where it came from.
Best Served
Pour this neat in a Glencairn and let it breathe for a full ten minutes — at 59.8%, the spirit needs room to unfurl. Then add water in drops, not splashes. A half-teaspoon at a time will unlock successive layers. On a cold evening, this is a fireside dram: no ice, no mixers, no distractions. If you're feeling sociable, pair it with a sliver of dark chocolate — seventy percent cacao or higher — and let the sherry cask sweetness and the cocoa bitterness argue it out on your palate. The peat will have the last word regardless.
