The Water in your Whiskey

The Water in your Whiskey

Time and time again, during our recent two day “immersion” at the Irish Whiskey Academy in Midleton, a few drops of water worked its magic at various tastings. Even when we were privileged to taste a 26-year old from a Bourbon cask in one of the warehouses.

“The cask is unique,” emphasised our tutor and guide Ciaran O'Donovan. “Both for its age and for the fact that the whiskey inside has ‘escaped’ been blended since 1991!” 

The bung was extracted and we examined the whiskey in the glass. “It has great legs, more viscous at this age, sweet with fruit flavours.” Then we added a few drops of water to cut the alcohol. Again the old H2O worked its magic, smoothing everything down a little, making it much more approachable without losing any of the essential character.


I know it’s only five or six drops but it always amazes me that this most freely available of liquids (in Ireland anyhow) can be so influential on a more expensive liquids. 
This mill stone, powered by the water wheel, was used to
grind down barley and malt to grist.
And especially so if the ABV is higher than the normal 40%. As it was in the on-site Irish Whiskey Academy, when we came to taste a New Make Pot Still Spirit whose ABV was, wait for it, 94.4%. It was fruity (mainly apple) and again the drop of water did the trick! Old-time whiskey drinkers knew this of course. That's why you see those water jugs in older pubs. 


Modern whiskey experts and masters regularly emphasise the point at tastings and talks. Two years ago, at the Ballymaloe Litfest, whiskey ace Dave Broom has us tasting a whiskey, Tullamore Dew Phoenix, a blend of all three Irish whiskey types:  “The Single Pot Still comes through. It has a rich dark character and you also note the effects of the sherry barrels. At 55%, it needs water. It is lovely, well balanced, with good characters.”
The old wheel, still turning.
And, of course, those few drops at the end of the whiskey’s life are just that. Water has been influential from the very start as it is a key ingredient. And that is why whiskey distilleries are located near a water source. Or more than one water source, which is the case with Midleton.

The most obvious source is the little river (not 20 kilometres long), the short Dungourney that flows through the town and, when you visit the distillery, you'll see the old giant water-wheel. Sometimes the river needed a boost and in 1834, the distillery purchased a stationary beam engine from the UK to aid the water-wheel during periods of low water. That engine was still in use when the ‘old’ distillery closed in 1975.


East Cork is an area rich in limestone and such areas have lots of caves. Just underneath the distillery, there are caverns full of nice cool water! The two other sources are bore-hole and the public supply.
The river was originally the main source of soft clear water supply for the Old Midleton Distillery, hence the big wheel! It is clean but has minerals. Once treated at the water treatment plant, the water is used for various activities including: brewing, distillation, fermentation, feeds recovery and boiler feed water.


The water from the cavern and borehole, located directly beneath the distillery, is ideal for cooling. It is used throughout the various processes: brewhouse cooling, still-house cooling and feeds recovery cooling.
Welcome to Midleton
The town’s water supply is used to reduce the spirit strength (cutting). It undergoes a thorough filtration and demineralisation process in the reverse osmosis treatment plant before it is used in the Vathouse.

The first spirit was distilled in Midleton Distillery in the early 19th century, the river and cool cavern water playing a key role. But so too did the distillery’s access to nearby Ballinacurra (where the Dungourney goes to sea). This easy access meant the the whiskey could be easily transferred by small lighters from Ballinacurra to the nearby port of Cobh and then onwards on salty ocean waters to countries throughout the world.


Distilling continued on the original site for 150 years (with many up and downs) and, in 1975, the new distillery was commissioned just a short stroll away. The original site is now a tourist attraction but whiskey is being made there again in the company's new micro-distillery. The story, including the essential water, continues.

Whiskey. What’s Wood Got To Do With It?

Whiskey.

What’s Wood Got To Do With It?
Cooper Ger Buckley with a stave secure in his "horse"
“You can take whiskey out of wood but you can never take the wood out of whiskey.” This was a quote in the sales literature when, a year or two back, Irish Distillers launched their Cooper’s Croze (one of a trio that also included the Distiller’s Safe and the Blender’s Dog).The influence of oak can be seen in the Croze through it’s vanilla sweetness, rich fruit flavours, floral and spice notes.  

Last week I had the privilege of seeing Ger Buckley, the master working cooper at Irish Distillers HQ in Midleton, in action, a bottle of the Croze he produced in the background and a croze in his hands. A croze? Ger has used a croze all his working life. He uses it to cut the grove along the top of the staves to hold the head (the circular cover) in place.

It is an old and simple tool, just like his other key implements, the hammer and the driver (both heavy), the carving axe (bevelled on just one side) and the adze (a shaping axe). The hammer, the axe and the adze are ancient tools, sacred tools in some cultures around the world.
Ger with croze in hand
Remember, there is no measuring in the cooperage, all done by eye, but each barrel or cask has a related compass. Other tools include the dog (used to insert the reed that makes a seal between upright and horizontal) and the horse and a stationery plane.

Our opening sentence indicates the importance of wood in the whiskey making process. Ger will say that it accounts for more than fifty per cent of the input to the final bottle and many distillers will agree with him.

Ger, a 5th generation cooper, had (up to a month ago) only ever used white oak. Very recently though, in Irish Distillers’ new innovative series Method and Madness, one of the whiskeys was finished in a Sweet Chestnut Cask.
The three basic tools: adze, hammer,  and axe
Both the American bourbon barrels and the Spanish Sherry butts are made from white oak but each performs very differently. Vanilla and caramel are among the flavours that the American version contributes while dark fruits (such as plum) and sherry flavours come from the European cask.

Recently, for the Midleton Dair Ghaelach whiskey, Irish oak, from ten trees, was used. The cooper told us that it is very sweet (there is sugar in oak!), chocolate too and vanilla, closer to the US than Spain. 

“Did you know that we once supplied staves to Spain?” said Ger. “Up to the 17th century, Ireland was covered in oak forests… the English, who took a lot for their naval forces, are often blamed for the decline..but we ourselves didn’t renew.”   

Ger collapses cask and re-assembles it, all in a few minutes, talking all the time!
Oak coverage here “is on the up again”. And the hope is to get it up to about 17% which is the European normal. “Not just oak though,” warned Ger. “We need bio diversity.”

And this diversity within the forest is good not just for the wood and its creatures but also for the distilleries, and anyone else who needs good timber. “We are looking for a large beam of oak.” And that is achieved by planting other species, beech for instance, close to the oak which then is forced to expand straight up and grow as a beam!

Oak for the cooperage is the most expensive. There must be no defects. The method of sawing, called quarter sawing, also leads to waste but it doubles the strength of the wood.
Ciaran O’Donovan makes a point about oak in the Whiskey Academy.
Good and all as the oak is, it is not perfect. Leaks do arise and most of these can be repaired quickly and without too much loss. But no one had yet found a solution to evaporation. It is about 2% in Ireland, about 30,000 bottles of Jameson a day! That is not too bad, compared to hot climates. In Tennessee it can reach 7%. All around the world, whether the distillery is producing brandy, whiskey or rum, the angels get their share!

Ciaran O’Donovan. of the Irish Whiskey Academy, who led our group in the 2-day immersion in all things whiskey, also filled us in on the importance of the wood (of oak in particular) saying 60% of the flavour comes from it. Did you know that Irish Distillers bring in about 140,000 barrels (with their internal surfaces charred) from America each year, swamping the few thousand Sherry butts (toasted internal surfaces) that come from Spain each November.

Just one corner of one warehouse
By the way, these butts belong to IDL from the very start. They buy them in the north of Spain; they are then taken down to the south, to Jerez and filled with sherry; after a few years they arrive in Midleton. Interestingly, when they come they will have up to five litres of sherry inside! Ciaran called the sherry barrel a "work of art" compared to the bourbon equivalent which, by comparison, has a lot of mechanisation in its production.

The butts (500l) add colour and tannin and flavours of dried fruit, nut, fig, even Christmas cake. The once-used bourbon barrels (200l) are empty! They have been especially sourced by three companies in the US and must be top class. Key flavours here are toasted wood, sweetness and vanilla.

IDL also source casks from other countries: Port pipes from Portugal, drums from Madeira, casks from Malaga (Green Spot 12 yo), casks from Marsala in Sicily, and wine barriques from Bordeaux (Green Spot Leoville Barton).
This comes with a disc of oak in the gift box
And the Irish oak? Well, we did get a chance to taste the Midleton Dair Ghaelach, matured in Bourbon casks and finished in Irish oak, a “project at its beginning”. It has a lovely nose, unique colours, vanilla and sweetness are prominent. 

IDL also import a small amount of Virgin oak from America’s Ozark Mountains and it is used, for example, in Jameson Gold Reserve, very sparingly in Barry Crockett Legacy. We came across it also when tasting a Pot Still 8 year old (where it was the only wood used). Ciaran indicated that while it may not be used on its own “it will improve a blend. Lots of uses for it here.”

In the cask, the young spirits will have a strong distillate character. The longer it spends in the cask, the greater the influence of the wood, and the more complex it becomes. The task for the distiller is to strike a balance between the two. I reckon they get it spot (excuse the pun) on most of the time in Midleton.

Midleton Distillery Tour. Happy Angels Hover Over 1.2m Casks

Midleton Distillery Tour
Happy Angels Hover Over 1.2m Casks

In Warehouse 39B
“This is the biggest Pot Still in the world,” said David McCabe, our guide on a tour of Midleton Distillery. The copper giant that he showed us in the old distillery has a capacity 143,872 litres and is no longer in use. Copper has some key properties that make it highly suitable for the task: it is easy to shape, has good conductivity and removes impurities.

In the new distillery, Midleton has the biggest operating stills in the world. And the three copper giants that we saw are due to be joined by another three later in the year. It is amazing to see these three in action, their contribution coming after the milling, the mashing and the fermenting.

And when they have their work done, the triple distillation (most Scotch whisky is distilled twice), the infant whiskey is piped out to holding tanks before being moved again to mature in casks, 1.2 million of them at last count! The giant warehouses make quite a “town”. For more details on how whiskey is made, and we are talking Irish here, the one with the “e”, see here.
The old distillery
Then anothering mind-boggling figure as we sipped from 24 year old and 17 year old whiskeys in one of the warehouses. The evaporation of the alcohol into the air, known in many cultures as the “angels share”,  amounts to some 24,500 bottles of Jameson per annum! Happy angels but there's some harmless pollution, a dark dust that settles on the warehouses. I have also seen it at the Remy Martin distillery in Cognac; hard to miss it there, as the buildings are white.

The difference between our tastings was not just the age factor. The 24 year old had been matured in bourbon casks while the 17 year was from a sherry cask so there was a colour and flavour difference as well.

The colour difference is easily seen at the Irish Distillers Pernod Ricard Whiskey Academy, the pride and joy of David, our Whiskey Ambassador. It is based in a restored building in the old distillery. Back to figures briefly. The old distillery take up about 12 acres while the new one is ten times larger.
The Academy class-room is state of the art, though David also uses the old chalk from time to time too to illustrate a point. Pupils are taken through the process, step by step, and get the opportunity to blend their own whiskey which they can take home with them.

But the theory lessons are short and you won't be bogged down with detail. In between, you are taken out and about on the site to see the practical side of the whisky making business. Check out those Pot Stills. Hands on. See and taste. Lots to see. You’ll notice the Americans and Spaniards put their bungs on the side of the cask, the Irish on the top because the casks are stored in an upright position here.

Since opening its doors in February 2013, the Irish Whiskey Academy has become the dedicated whiskey institute of Irish Distillers Pernod Ricard, hosting courses that focus on the production and heritage of Irish whiskey produced at Midleton. It started off to train the distillery sales force but now there are courses to suit everyone and many students come from abroad. Check it out here  and give yourself a present!

Guess which came from the sherry cask!
One type of whiskey, the Single Pot Still, is the real Irish. This spirit almost died a death, for many reasons, but is now on the up and up.  Check the story of this premium product out here where you’ll read that Jameson is not a Single Pot Still but Redbreast is. 

If you join the Stillhouse (no fee), you’ll get special offers from time to time. I just ordered one bottle of a limited edition of Mano a Lámh, a Redbreast made in special sherry casks. But you’d better act quickly as I believe there are not very many left! Must say though, aside from the odd offer, there is a wealth of information on the site and it is well worth a look.


After that, why not take a trip to Midleton to take the distillery tour. Details here.

Cheers. David and Yours Truly,
after breaking in to the 24 year old!
Evidence is evident!
