Zacapa XO is produced in small handcrafted batches and represents the ultimate expression of the unique "Sistema Solera" aging and blending, which takes place in the cool air of the Guatemalan highlands, 2300 meters above sea level. This process involves the hand selection of rums aged between 6 and 25 years that are blended as they age in sequence of barrels that previously stored robust American whiskeys, delicate sherries, fine Pedro Ximenez wines and finished in French oak casks which previously aged Cognac.

As you’re reading this blog and are possibly a customer of Just Whisky Auctions, it’s a fair assumption that you’ve visited more than a few distilleries and taken their tour.

That being the case, your guide almost certainly paused to point out the malt mill. More often than not, it’s a Porteus mill, though you might see the occasional Boby and even the odd Buhler mill.

But if it’s painted in a distinctive, unshowy shade of dark red then what you looked at was a Porteus mill (we’ll come back to the Boby mills shortly).  They’re sturdy little things, standing four-square in the mill room, ready to receive another load of malt, quiet occupants of an unobtrusive corner of the distillery that just get on with their job in a modest and understated way.

If the guide didn’t pause and point it out, a Porteus mill would never shout or draw attention to itself, you feel; happy to do an honest day’s work and then await the next consignment of malt to be turned to grist.

At this point, your guide quite probably explained that the mill was quite old and that the Porteus firm had gone out of business, outlived by the durability and simple excellence of a product so good and so enduring that it broke the company.

So well made that they required relatively little maintenance and with little or no demand for new machines both Porteus and Boby closed down many years ago.  They were outlived by their equipment and undone by the slump in whisky production of the 1970s and 80s and the ruthless consolidation of the brewing industry, meaning fewer and fewer small independent breweries.  Sadly, quite a few mills will have been scrapped which, until recently, hasn’t been a problem.

But it’s worth taking a closer look at these tough and functional looking machines and, if you do, there’s a good chance you’ll see a modest plaque somewhere on the side carrying a telephone number and the name Ronnie Lee.

Some years ago I noticed this on Jura and then, shortly afterwards, at Tobermory distillery and then again at a number of Speyside distilleries. So I began asking various guides ‘Who is this Ronnie Lee?’  No one knew – but as soon as I asked some real production people (as opposed to the friendly guides who for the most part are essentially a PR front and equipped with a marketing script) the pieces of a fascinating story fell quickly into place.

Well it turns out that, in a world of tattooed, bearded Brand Ambassadors with their hipster tweed caps, and rock-star Distillery Managers who jet from whisky show to whisky show, Ronnie Lee is a quiet hero. Yet he doesn’t give master classes, doesn’t blog and he’s definitely not part of the fashionable crowd that increasingly follow whisky these days.  But he – together, these days with son Gareth - are the men who mends the mills.  And, if you think about it, without their expertise there would be no whisky.

Working from their modest base near Chepstow, they run Euro Mechanical Engineering working as freelance millwrights.  As such, they spend most of their working days life in maintaining, servicing and, on occasion, restoring Porteus and Boby mills for the brewing and distilling industry.

Their surroundings are as far removed from whisky’s new image of sophistication, glamour and luxury as you might conceivably imagine, yet they carry out vital work as one of an elite group of engineers who keep these vintage machines in working order. Unsung and unheralded, they are essential to the smooth and effective operation of much of the distilling industry, here and internationally.

In fact, they work for Diageo, Chivas Brothers, Glenmorangie, Highland Distillers and Ian MacLeod Distillers, as well as a number of independent breweries and distilleries as far flung as Sweden, Italy and even the USA. If you want a vintage malt mill, or need one restored, Ronnie Lee is the man you call.

And that brings us to a fascinating twist in the story.  Some years ago, Ronnie acquired all the plans for the Boby mill when that firm closed down. With access to that unique archive, it was Euro Mechanical Engineering’s proud boast that, in theory, they could build a brand new Boby-style mill from scratch based on the original blueprints but updated for greater efficiency and cleaner running.

But why would you, when the originals have a working life of a century or more? Well, basically, they are desperately hard to find and with new distilleries and small breweries being built at an unprecedented pace, there’s a need for equipment of established high quality with a proven heritage.  Even the shiniest of new state-of-the-art distilleries may be discreetly supplied by a 50 or 60 year old machine which, come to think of it, is something quite amazingly heart-warming. But there just aren’t enough to go around.

And so it has come to pass that a new Boby mill has indeed been built and is now heading off to its eventual home in a soon-to-be-opened whisky distillery (which is another story, which we’ll come to in a moment).

The mill, of 4-5 tons capacity, is the product of 12 month’s work by Ronnie and Gareth Lee. The original design has been improved, Gareth telling me that while the exterior closely resembles an old-style Boby, the gears have been done away with, the roller bearings switched to a spherical shape and a double-edged synchronized belt fitted. If, like me, that’s double Dutch to you, I’m assured it means cleaner running (no oil), greater energy efficiency and potentially faster running speeds if desired by the operator. Everything has been built from the ground up with a local foundry providing custom-made castings for the bearings, which were then hand finished by Gareth.

But who has commissioned this work and where is this marvel of skillfully modernized vintage engineering to be found? Let’s hear it for the new owners, the family-owned and independent Ian Macleod Distillers, well-known for their Glengoyne and Tamdhu single malts, the imaginative reopening of Rosebank and their Edinburgh Gin brand.  They are also partners in the proposed Laggan Bay project which, if everything goes to plan, will be Islay’s twelfth distillery.

So the Boby is destined for a Hebridean home? Well, no. In fact, it is travelling around 4,000 miles to Una, a town in the southwestern Himachal Pradesh state in northern India where Macleod Distillers are currently building on a greenfield site.  The distillery, expected to be operational later this year, is designed to produce around 1.0m litres of spirit annually of Indian whisky.

Beyond that, Ian Macleod were tight-lipped though my own lengthy on-line research turned up an Environmental Impact report from the Himachal Pradesh State Pollution Control Board.  From that very comprehensive document we learn that “The project proposes to produce Malt Spirit, part of it matured for at least 2 years and above years for supplies to IMFL [that’s Indian-Made Foreign Liquor] industry for blending in various proportions and part of the matured malt spirit will be matured for more than 3 years to be called as Whisky under International norms and bottled as Indian Single Malt whisky for the Indian and export market”.   Indian Single Malt Whisky from Ian Macleod Distillers – that’s something not yet widely reported and quite a feather in the cap of relatively small independent Scottish distillers.

According to the report, the total cost is approximately £5m – quite the bargain by UK standards. 
Naturally I enquired as to the price of the mill and naturally, and quite correctly, Gareth Lee would not be drawn into the specifics. But he did hint that if you wanted one for your project you could expect to wait some 12 months or so (they’re busy) and expect to write a cheque for rather more than  £100,000.

So this is a mill that grinds slowly but is exceeding fine; evidently a labour of love and a source of great pride – and why not, because as Gareth assured me, “it will be working long after I’m in the ground.”  I wonder if in fifty or more years curious visitors will be regaled with the story – I certainly hope so.
