Just like every whisky enthusiast, I have been accumulating samples. And forgetting about them. No more. Today I am kicking off a new sample-focused series: Rule of Thumb. For this first “release”, I am starting with two Bruichladdich samples, the 18 and the 21, sold under the Re/Define series.
The samples come straight from Bruichladdich Distillery. I bought them back in 2024 when I visited, which I detailed in a post from about two years back – check it out here. I had been tempted to grab a bottle of the 18 in particular, but I knew I could probably grab a bottle back home if I wanted after trying it first. The samples ended up in a box, with others from the same and following trips. They remained overlooked. I always played with the idea of giving samples their space on the blog, but always procrastinated in favour of full reviews. With Rule of Thumb, I am diving right into my sample heap- no special theme or story, just the unfiltered first impressions. Before I dive into the Bruichladdich Re/Define 18 and 21, let me explain how this is different from my regular reviews.
How to read Rule of Thumb
Rule of Thumb is a first impression, not a review. Reviews come with multiple tastings, looking for the fine detail and that elusive note that is just on the tip of my tongue. These are first impressions, from a single tasting, no repeats. No full score either, just four tiers which indicate enjoyment. Nothing else. No judgement on value, and none on the distiller’s craft. And no relation to the out-of-ten scores in my reviews.
Here is how to read the verdicts:
👎 Thumbs down: I did not like it.
😏 Meh: ok whisky, nothing wrong with it but failed to excite me.
👍 Thumbs up: I enjoyed it.
👍👍 Double thumbs up: I love this, and I want to hunt a bottle and spend proper time with it.
Bruichladdich Re/Define 18-year-old

Specs
ABV: 50%
Natural colour: Yes
Non-chill filtered: Yes
Casks used: “primarily in ex-Bourbon casks and a small number of wine casks”
Bruichladdich’s new 18-year-old, first released as part of its ‘luxury’ Re/Define line in 2024.
Tasting Notes
Nose: There is a hint of cut grass, which almost immediately disappears to give way to sweet fruit, grain and creamy lactic notes. Peach, melon, even a hint of pineapple. Rich natural vanilla. Then rolled oats, golden syrup and crème fraîche. A sprinkling of pipe tobacco and liquorice wrap things up.
Taste & finish: Lovely thick texture, creamy. Loads of peach again, but also ripe golden apples, melons. A bit of ginger and white pepper spice. Buttery vanilla custard, spooned on top of a shortbread biscuit. A touch of astringency and acidity at the end, which work like a charm, balancing things out. The finish is very long and vibrant.
Verdict
👍👍 Double thumbs up; don’t be surprised if this becomes a full review at some stage. This is an elegant, balanced dram. Not flashy, but captivating.
Bruichladdich Re/Define 21-year-old (Travel Retail Exclusive)

Specs
ABV: 50%
Natural colour: Yes
Non-chill filtered: Yes
Casks used: 80% ex-Bourbon, 20% ex-Sherry (Oloroso and PX)
The new Bruichladdich 21-year-old is the Travel Retail exclusive bottling for the Re/Define line.
Tasting Notes
Nose: The first note is more tactile than aromatic. Dusty bookshelves, peanut husks and dry grains. Baked fruit – apple and peach mostly. A touch of baking spice and a hit of natural vanilla. Light caramel.
Taste & finish: Rich, reaching into syrupy territory. There is less of that dry sensation I got on the nose. Instead, we veer into autumnal baking. Sweet, with baked apples, smothered in vanilla syrup sprinkled with raisins, baking spice and Demerara sugar. A faint floral note. Some well-oiled leather, treacle and a touch of cask tannins. Long finish, sweet and rich with warm spice.
Verdict
😏 Meh. Nothing wrong with the 21. It is a well-made, solid dram. It just failed to excite me. The extra age removes some vibrancy, replacing it with dry, dusty notes on the nose and a sweeter, heavier palate, both of which left me wanting more complexity.
This first Rule of Thumb has a clear favourite. The Bruichladdich 18-year-old is a really elegant treat, while the 21 fails to deliver the same enjoyment. Who knows, maybe on its own I would have liked it better.. but that’s the gift and curse of samples; once they are gone, they are gone.
