Last weekend I had a few friends in town and oddly enough we decided to go along to one of my favourite whiskey bars for a drink or two. Over a bottle of Glenrothes Select Reserve, we started to discuss the steps involved in making whiskey and some of the differences between Irish and Scottish whiskeys. For some of us it was a refresher course but for others it was just a good excuse to seat back with a glass of whiskey and listen to the stories unfold. So below I have summarised some of the key points we touched on (ie. Left out most of the swearing about which way is better).
Malting
The barley is first steeped in water and then removed and allowed to germinate for a few days. After this, the barley will then go to the kiln for drying, a process that stops the germination. Irish distillers normally dry their barley in a closed kiln, this eliminates the presence of smoke and is believed to give a cleaner taste to the final whiskey. Scottish Whisky on the other hand may add peat at this stage to give a smoky flavour to the whisky. After the drying is complete, we are left with the malted barley.

Mashing
To begin mashing the malted barley is first milled into a girst or course floor. It is then mixed with hot water in a large vessel called a “Mash Tun”. The mash is stirred in order to help the starches convert into sugar. The mashing process is finished when a sweet liquid called “Wort” is drawn.
Also, don’t worry about the spent grains or draff, these are used by local farmers for cattle feed.

Fermentation
Next the “Wort” is cooled and pumped into “Wash Backs”. It is here where the yeast is added and the fermentation process begins. The yeast will feed on the sugar to produce a low strength alcohol (approx 6-8%) and lots of carbon dioxide. Also during this process, congeners are produced. Now while strictly speaking congeners are impurities, they are essential in giving whiskey its taste, aroma, flavour and colour. After about 2 days in the “Wash Backs” the fermentation process will die down and we will have what is called the “Wash”.

Distillation
The shape of the copper pot still is known to affect the characteristics of the whiskey and for this reasons, each distillery has kept their own unique still exactly the same for many years.
The distillation process begins by first distilling the wash in a wash still, this creates a distillate know as low wines with an alcohol volume of around 20%. The low wines will then go to the spirit still for distillation. The distillery will collect the centre cut or heart of the run in a spirit receiver. This collected spirit will now have an alcohol volume of around 68%.
In most regions the “wash” is distilled just twice but in Ireland, in order it create a smoother whiskey, it goes through this process three times, thus earning it the title of “triple distilled”.

Unfortunately around this stage, we got off topic and started to talk a little more about the Glenrothes that we were drinking and less about the process for making whiskey. However, not to worry, over the course of the next month or so, I know I will be drinking with them again and discussing the even more interesting parts of maturing and blending whiskey.
So as an old Irish blessing best puts it:
“May the road rise up to meet you,
May the wind be always at your back.
May the sun shine warm upon your face,
The rains fall softly on your fields.
And until we meet again,
May God hold you in the palm of his hand.”
