Irish and Scottish whiskies have interwoven chronicles that date back almost a thousand years. However, for the cutting-edge bourbon fan, knowing the nuanced contrasts between these two famous kinds of bourbon will open a totally different universe of flavors for your taste buds.
In contrast to their Canadian and American bourbon cousins, by far most of the two Scots and Irish refineries neglect the zest notes innate in Canadian mixed whisky, American rye bourbon and most whiskeys. Yet, as you’ll find in this post, that doesn’t restrict the scope of flavors accessible in the Irish and scotch sub-classifications. Despite what is generally expected, with hundreds of refineries dedicated to bourbon creation sprinkled across the two islands, it would take a long period of investigation to taste them all.
Examine on to see our profound plunge into how pound charges, ageing, the development interaction, and the imaginative utilization of wooden barrels and a large group of different stills during the refining system make the ideal segue into the more extensive universe of bourbon.
One speedy note before we start: Scots spell it ‘whisky,’ while the Irish use ‘bourbon.’ thus, you will see the two spellings all through this post.
Key Differences between Irish Whiskey and Scotch
Scotch depicts whisky made in Scotland. Irish bourbon is made on the island of Ireland.
As you’ll see all through this post, there are many shades of subtlety when contrasting the two. Be that as it may, as a general idea, the bourbon’s starting point may be an incredible initial step.
There is a ton of disarray about the principle contrasts among Scotch and Irish bourbons. One explanation might be the plenitude of inadequate data on the web. While talking about ageing, refining and development processes, many site pages dedicated to this subject contain expansive consensuses shorn from their unique situation.
To put any misinformation to rest, we will offer a profound plunge into the creation cycles of these spirits that we trust helps address the many inquiries out there.
1. Fermentation Process
The greatest contrast between the ageing cycles for malt scotch and Irish bourbons is the select utilization of malted grain for single malt scotch versus a mix of malted and unmalted grain in the creation of Irish pot still bourbon.
Both Irish and Scots distillers each have very long term accounts of avoiding the ruler’s duty gatherers. In Ireland, the utilization of unmalted grain occurred because of a proviso in bourbon charge law.
Customarily, a part of malted grain was utilized in each bourbon pound because of the enzymatic properties of the grain. To malt grain, a brewmaster or bourbon producer first splashes the grain to actuate maturation, then, at that point, rapidly uncovered the growing seed to hotness to stop the cycle. This little grain shoot contains enough catalysts to assist with changing over the starches in the whole squash — regardless of whether it be joined with wheat, corn, rye or another grain — into sugars, the yeast would then be able to transform into liquor.
At the point when the King of England authorized an assessment on malted grain in British-controlled Ireland in 1785, Irish distillers found a workaround to stay away from what many thought about an unfamiliar expense. They joined malted grain and unmalted grain to make a malt bourbon that left them at risk for just a negligible part of the due charges. This style became known as Irish pot still bourbon, systematized in Irish law today as containing at least 30% malted grain and 30 per cent unmalted grain in the crushing charge — or rundown of grain fixings. The utilization of ‘crude grain’ in the squash gives a complicated and one of a kind rugged character and gooey mouthfeel.
Scotch single malt, conversely, should contain 100% malted grain in the grain bill.
2. Distillation Process
It is by and large expressed that Irish bourbon is refined multiple times while scotch is refined twice. There is truth to this, however — and this is a major yet — handle the setting of the particular sub-classifications of every item type to see what this creation procedure means for flavor.
The main significant differentiation is among malts and mixes. One distinction between the two is the utilization of copper pot versus segment stills.
Malt bourbons should be made in customary copper stills from 100% grain. By and large, distillers in Scotland utilize two refining processes, while Irish distillers use triple refining to make malt bourbon.
Grain bourbons are regularly made utilizing the more present-day and modern persistent segment refining. These can be produced using any cereal grains, yet by and by, they are by and large produced using generally wheat or corn, with some malted grain utilized for enzymatic transformation of starches.
Mixed bourbons depict any mix of malt and grain bourbons. With the exception of mixed grain bourbon, both Scotch and Irish mixed bourbons contain a part of copper pot malt bourbon — a particular distinction from mixed American and Canadian whisky.
Once more, we’ll examine many shades of subtlety in ensuing segments, however, understanding the idea driving the terms malt and mixed bourbon will go far in coming to an obvious conclusion with what’s inside the jug.
3. Maturation Period
The standards for scotch were systematized by the United Kingdom, while Irish bourbon laws were sanctioned by the Irish assembly or Oireachtas. Therefore, the lawful structures for the two refined soul types have numerous distinctions. Be that as it may, as far as development, they concur: three years in oak containers – or, as distillers frequently say, three years and at some point.
While Ireland has no size limit for the wooden barrels utilized during development, scotch whiskies have a greatest limit of 700 litres or 185 gallons for their oak containers.
Since whiskey and other American bourbons require new American singed oak barrels, most containers utilized in the development of both scotch and Irish bourbons are utilized American barrels. Truth be told, numerous distillers in the British Isles have coopers of their own that assist with reconditioning old whiskey containers. For instance, the 250-litre hogshead container famous for scotch whisky producers is made with reconditioned fights from the standard 53-gallon (200L) whiskey barrel.
Yet, American oak barrels are by all account not the only sort of container utilized for development. Distillers use auxiliary containers from across the universe of refined and aged drinks. Among the expert blender’s stockpiles is the 650-litre Madeira drum from Spain, the 550-litre Port line from Portugal, 500-litre butts and puncheons, the 350-litre cognac container made of Limousin oak from France, hogshead and whiskey barrels produced using American oak and the 125-litre quarter container. Each style of barrel particularly affects the general character profile of the completed item.
