Irish doctoral pupil Fionnan O’Connor has been chasing ghosts. He isn’t pursuing the spectres of deceased warriors or poets, however relatively forgotten Irish drinks. In a private quest that has taken him from quiet college libraries to trendy distilleries, he’s decided to revive uncommon spirits made utilizing old style strategies and elements, particularly pot-still whiskies. As a part of his Ph.D. thesis in ghost whiskeys, O’Connor is resuscitating pot-still recipes that haven’t been tasted for greater than 100 years.
These long-lost drinks might quickly enliven events throughout Eire, identical to they did again within the 1800s. However that is determined by whether or not O’Connor and Boann Distillery (his accomplice in reviving these whiskeys) can grasp discarded recipes, be taught difficult distillation strategies from bygone eras, and impress a panel of whiskey specialists.
O’Connor admits he isn’t fairly certain how he ended up on the helm of this venture. Though he describes himself as a whiskey lover “since I used to be sufficiently old to drink,” he was on a completely completely different profession path 10 years in the past, finding out medieval historical past and literature.
Whereas finishing that diploma, at UC Berkeley, O’Connor started part-time work as a speaker at a whiskey bar and as a drinks-festival consultant for Diageo, one of many world’s largest distillers. Each jobs got here with an important perk: numerous free, premium alcohol. O’Connor shortly turned besotted with whiskey. What began as a fling snowballed right into a deep romance.
So deep, in reality, that it produced a ebook. Combining his literary schooling and whiskey data, O’Connor printed A Glass Aside: Irish Single Pot Nonetheless Whiskey in 2015. It was throughout analysis for this ebook, which included numerous visits to distilleries, that O’Connor realized of the various Irish whiskeys that had disappeared over the previous century.
“In 2014 there have been only a few Irish pot-still whiskeys left to jot down about,” says O’Connor. “Even for whiskey followers, Irish pot nonetheless as a method was one thing of an unknown drink in these days.”
In 1915, Eire was the world’s main producer of whiskey, pumping out 12 million instances a 12 months from 88 licensed distilleries. Then, within the house of 30 years, the trade was decimated by two world wars, British commerce restrictions, Prohibition in the USA, and Eire’s bloody combat for independence from the UK.
Lots of these 88 distilleries disappeared, together with the normal recipes they used. By the Nineteen Seventies, solely two main whiskey distilleries remained in Eire. Then, in 1988, highly effective French distilling agency Pernod Ricard purchased Irish Distillers and pumped cash into advertising their whiskeys, launching a large resurgence. Now Eire is house to greater than 30 whiskey distilleries.
This growth has made it an ideal time for O’Connor to launch his ghost-whiskey venture. Whereas researching his ebook, O’Connor secured funding for his Ph.D. from the Irish Authorities, which recurrently gives grants to lecturers who examine missed parts of Irish tradition. In 2018, O’Connor started this thesis, which tracks the modifications in mash payments (whiskey-grain recipes) from 1760 till the Nineteen Seventies, by which era there have been few remaining Irish pot-still whiskeys, a method made utilizing a wider vary of grains that boasts a thicker consistency and stronger flavors.
This requires an enormous quantity of legwork. The forgotten whiskey recipes aren’t simply sitting on pub cabinets, however scattered throughout Eire, hidden in archives. So O’Connor traverses the nation, visiting universities, libraries, and authorities places of work to pore via previous paperwork and search databases. Some days, his labor bears no fruit. Others, he’s thrilled to unearth recipes lengthy consigned to historical past.
Then he faces the true job: lifting them off the web page and bringing them again to actuality. “Irish pot-still whiskey is a really completely different animal altogether,” O’Connor says of his obsession with reviving recipes of this model, evaluating them to the lighter-tasting, more-popular Irish blended whiskeys. “The raw-barley viscosity of the old-school stuff was a part of what drove me to jot down the ebook within the first place.”
A novel product of Eire, pot-still whiskeys are differentiated, largely, by the distillation gadget that provides them their title. Pot stills are bulbous distillation instruments created from copper, whereas hottest Irish whiskeys are actually made with taller, narrower column stills constructed from stainless-steel. Pot stills and column stills each have a predominant vessel (known as a kettle) that heats a combination of water, grain, and yeast till the alcohol separates in vapor kind, passes via a number of different vessels, and is condensed again into liquid.
The latter kind of nonetheless has a column, separated by perforated plates, which sits above the kettle. Because the vapor rises from the kettle, these plates additional isolate the alcohol, which is pushed to the highest of the column, gathering near-pure alcohol.
The pot nonetheless, in the meantime, produces alcohol with a a lot decrease purity. This less complicated, extra old style distillation gadget sends vapors from the kettle up via a slim, hook-shaped chamber and down right into a spiral copper tube, inside which the vapor is condensed into liquid.
Column stills, then, are extra environment friendly and cost-effective, which is why they dominate the trendy market. And blended Irish whiskeys usually combine a less expensive spirit with a single-malt whiskey, which additional decrease prices in comparison with pot stills.
It is just in recent times, because the trade recovered, O’Connor says, that pot stills have begun to make a comeback. Whereas trendy shoppers are accustomed to the sunshine style and really feel of blended whiskeys, many whiskey connoisseurs respect the heavier, thicker product of pot-still whiskeys, which have a powerful barley taste and spicy notes.
The larger viscosity of pot-still whiskey comes from mixing uncooked barley grist into the malt. Pot-still whiskeys are then triple distilled and matured in oak casks. “That grist creates a a lot heavier, oilier drink than say a single malt,” O’Connor says. “That oiliness is what drives loads of trendy Irish pot nonetheless’s vital acclaim.”
To resurrect historic pot-still whiskeys, O’Connor sought out an Irish distillery prepared to affix his mission. He discovered Boann Distillery, a newcomer that started distilling in late 2019, led by seemingly Eire’s youngest head distiller, Michael Walsh.
In response to Boann director Sally-Anne Cooney, the largest problem of ancient-whiskey recipes is experimenting with grains apart from the normal barley, reminiscent of oats, wheat, and rye. This number of grains means the whiskeys are much less predictable in style than the widespread blended varieties (some are spicier, some are heavier) and require cautious changes of temperature, fermentation time, and yeast additions.
“I used to be primarily afraid that we’d break the tools,” O’Connor says about their pot-still experiments. “Even in brewing, oats have a status for being difficult to work with, and I used to be afraid within the larger portions they may flip to porridge and burst a pipe or one thing terrible. I keep in mind the day the best oat mash went via and there was an enormous sigh of reduction.”
A number of of those previous pot-still whiskeys are actually maturing in casks, and O’Connor is feeling optimistic. “Naturally [I was] afraid they’d style like shite, however all of them style entrancing.”
O’Connor says these revived whiskeys will ultimately be launched to the general public, however first they are going to be style examined by a panel of 30 whiskey distillers, blenders, and critics from Eire and Scotland. (The tastings have been delayed by Covid-19.) Scientists from Scotland’s Heriot-Watt College are additionally set to do a chemical evaluation. Already, although, some whiskey fans have paid deposits to safe one of many casks created by O’Connor and Boann.
A few of these pot-still whiskeys might solely be revived quickly. Others, although, may very well be set for industrial comebacks. Boann is especially enthusiastic about “Prestons High quality Irish Whiskey.” Prestons, then, is a ghost which will proceed to stroll the earth or, maybe extra precisely, dance on the palates of Irish whiskey followers.
