The world shut down for the better part of two years and it’s been almost three since I’ve seen a Nine Leaves rum, but the little one-man Japanese distillery I have written about with such affection since 2014 has continued chugging along, releasing its young rums every six months to a year and somehow managing to make rent. Several festivals ago I remember Yoshiharu Takeuchi (the owner) telling me that because tax laws in Japan were so obscure, it was not worth his time to age for more than two years – and indeed, many of his initial releases were a mere six months old. That they retained real quality and became popular and sought after is a testament to his skill as a distiller and as time went on he upped his ageing to two years, with occasional one-offs exported at slightly older.
Something clearly changed in the intervening years, though, because the latest in the premium line, the Encrypted IV, is a five year old rum, and it’s quite a nifty expression to try, if you can get some. As before it’s a blend of several different bits and pieces aged in different ways but this time I could not get the details of the blend so it surely does deserve its title. We know it’s a pot still product issued at 58%, released in 2021 and aged five years, that’s about all…yet within those brief statistics is a rum of real quality.
Let’s start with how it smells. It’s rich, nicely so, yet not too heavy – sweet plum wine, heavy and sulky, giving up its charm, with reluctance. Orange rind (I kept thinking of Cointreau or Pyrat’s), unsweetened high quality chocolate, caramel and molasses, balanced by fresh green tea, apples and green grapes. Some brine and olives, cereals and flowers, and it reminds me of a well done sherry-aged Glendronach at times.
Tasting it reveals a dry, pungently plush rum whose fruitiness bent towards dark: black grapes, plums, prunes, and a blue-and-blackberry slushie. It’s not overly sweet, which allows muskier notes of salt caramel ice cream, vanilla, and molasses to come forward. Plus, oh, some citrus, cloves, polished old leather satchels, a touch of brine. These all help give it some oomph, but I tell you, this thing is as seriously astringent as my mother-in-law’s sense of humour. It closes with a really nice dark red wine filip – a Bordeaux, perhaps – and finishes dry, fruity, salty, with reminders of miso soup and a good quality sweet soya.
The rum is really quite something: every time I go back to the glass I get a little more, something a little different. It starts off solid but ends up so clear and clean it could almost be an aged agricole. The darker molasses and caramel elements are held back, allowing other aspects of the construction to shine, and this bends the taste away from a mere copy of better-known Caribbean fare, and into its own unique ecosystem. The Encrypted IV never strays too far from real rum roots (I’ve commented before about the way aspects of shochu and awamori sometimes infuse other Japanese rums) yet carves out a niche all its own, and this is to its — and our — benefit.
Yoshi-san is a fun and quirky guy, with a great sense of humour. I’ve known him for many years, met him many times, and he is always looking for new and interesting ways to make his rums, never regressing or backsliding. Either he stays at one level of quality, or he gets a little better, and loses no skill. Here he has made a rum that is so well assembled, goes down so easy, that we hardly realise how traditional it is underneath…maybe that’s why it’s only afterwards that we respond to it with familiarity. It’s an essay in contrasting yet complementary tastes, with that distinct structure which one always senses with Nine Leaves’ rums. It takes us for a ride and we never know how much we are getting, and in that way it’s like a small but powerful locomotive pulling a helluva long train.

Does this multiple wood ageing result in anything worth drinking? Yes it does – the extra year seems to have had an interesting and salutary effect on the profile – though at 42.7% it remains as easy and soft as its siblings. The nose, for example, is a nice step up: cardboard, musty paper, some dunder of spoiled bananas skins, plus strawberries and soft pineapple or two and brine (which, I swear, made me think of Hawaiian pizza). Caramel and bitter dark chocolate round things off. It’s a relatively easy sniff, inoffensive yet solid.
This process provides a tasting profile that reminds me of nothing so much than a slightly addled wooden still-rum from El Dorado: it’s sweet, feels the slightest bit sticky, and has strong notes of dark fruits, red licorice, plums, raisins and an almond chocolate bar gone soft in the heat. There’s other stuff in there as well – some caramel, vanilla, pepper again, light orange peel, but overall the whole thing is not particularly complex, and it ambles easily towards a short and gentle finish of no particular distinction that pretty much displays some dark fruit, caramel, anise and molasses, and that’s about it.
So, until we know more, focus on the rum itself. It’s quiet and gentle and some cask strength lovers might say – not without justification – that it’s insipid. It has some good tastes, simple but okay, and hews to a profile with which we’re not entirely unfamiliar. It has a few off notes and a peculiar substrate of something different, which is a good thing. So in the end,
The Old Monk series of rums, perhaps among the best known to the Western world of those hailing from India, excites a raft of passionate posts whenever it comes up for mention, ranging from enthusiastic fanboy positivity, to disdain spread equally between its lack of disclosure about provenance and make, and the rather unique taste. Neither really holds water, but it is emblematic of both the unstinting praise of adherents who “just like rum” without thinking further, and those who take no cognizance of cultures other than their own and the different tastes that attend to them.


The Cor Cor “Green”, cousin to the 
Given Japan has several rums which have made these pages (
The Cor Cor Red was more generous on the palate than the nose, and as with many Japanese rums I’ve tried, it’s quite distinctive. The tastes were somewhat offbase when smelled, yet came together nicely when tasted. Most of what we might deem “traditional notes” — like nougat, or toffee, caramel, molasses, wine, dark fruits, that kind of thing — were absent; and while their (now closed) website rather honestly remarked back in 2017 that it was not for everyone, I would merely suggest that this real enjoyment is probably more for someone (a) interested in Asian rums (b) looking for something new and (c) who is cognizant of local cuisine and spirits profiles, which infuse the makers’ designs here. One of the reasons the rum tastes as it does, is because the master blender used to work for one of the awamori makers on Okinawa (it is a spirit akin to Shochu), and wanted to apply the methods of make to rum as well. No doubt some of the taste profile he preferred bled over into the final product as well.




I’ve never been completely clear as to what effect a resting period in neutral-impact tanks would actually have on a rum – perhaps smoothen it out a bit and take the edge off the rough and sharp straight-off-the-still heart cuts. What is clear is that here, both the time and the reduction gentle the spirit down without completely losing what makes an unaged white worth checking out. Take the nose: it was relatively mild at 40%, but retained a brief memory of its original ferocity, reeking of wet soot, iodine, brine, black olives and cornbread. A few additional nosings spread out over time reveal more delicate notes of thyme, mint, cinnamon mingling nicely with a background of sugar water, sliced cucumbers in salt and vinegar, and watermelon juice. It sure started like it was out to lunch, but developed very nicely over time, and the initial sniff should not make one throw it out just because it seems a bit off.
Consider first the nose of this 





Anyway, when we’re done with do all the contorted company panegyrics and get down to the actual business of trying it, do all the frothy statements of how special it is translate into a really groundbreaking rum?
Like most rums of this kind, the opinions and comments are all over the map. Some are savagely disparaging, other more tolerant and some are almost nostalgic, conflating the rum with all the positive experiences they had in Thailand, where the rum is made. Few have had it in the west, and those that did weren’t writing much outside travel blogs and review aggregating sites.

Because for the unprepared (as I was), the nose of this rum is edging right up against revolting. It’s raw, rotting meat mixed with wet fruity garbage distilled into your rum glass without any attempt at dialling it down (except perhaps to 40% which is a small mercy). It’s like a lizard that died alone and unnoticed under your workplace desk and stayed there, was then soaked in diesel, drizzled with molten rubber and tar, set afire and then pelted with gray tomatoes. That thread of rot permeates every aspect of the nose – the brine and olives and acetone/rubber smell, the maggi cubes, the hot vegetable soup and lemongrass…everything.
Now here’s an interesting standard-proofed gold rum I knew too little about from a country known mostly for the spectacular temples of Angor Wat and the 1970s genocide. But how many of us are aware that Cambodia was once a part of the Khmer Empire, one of the largest in South East Asia, covering much of the modern-day territories of Thailand, Vietnam, Laos and Viet Nam, or that it was once a protectorate of France, or that it is known in the east as Kampuchea?
Thailand doesn’t loom very large in the eyes of the mostly west-facing rum writers’ brigade, but just because they make it for the Asian palate and not the Euro-American cask-loving rum chums, doesn’t mean what they make can be ignored; similar in some respects to the light rums from Puerto Rico, Dominican Republic, Panama and Latin America, they may not be rums
