There are two tours that we simply had to go on while we were here. Having enjoyed both of these products over countless occasions, it seemed only fitting to see how they're made. I refer, of course to Jameson Whiskey and Guinness.
The photo below shows one of the copper distillation towers and a rather peculiar class cylinder atop one of the old smokestacks. I never found out what the tower was, but I assume it was a private bar.
The Jameson and Guiness tours began the same way, with a description of roasting barley, malting the barley and making beer. Whiskey begins as beer, although without any hops, before it is distilled alcohol of an appropriate proof. American whisky is distilled once, Scotch twice and some others, namely Jameson, are distilled three times. This makes the alcohol smoother, or so they say.
The other particularly interesting fact I learned was that a great deal of the alcohol evaporates while the whiskey (spelled with an "e" in Ireland) is matured in oak barrels. After it ages for five years, about 20% of the content of the barrel has evaporated, and after 12 years nearly half has been evaporated.
One last Jameson factoid. It is aged in oak barrels that had previously been used to age Sherry, Port and American Whisky.
Now on to Guinness. This tour was self-guided and takes you through six different floors of the old brewery. Arthur Guinness was so confident that he would be able to convert an old, run-down brewery into a successful business that he signed a 9,000 year lease for the property. The original lease can be seen at the start of the tour.
Another interesting fact is that the Guinness brewed in Dublin is shipped to Europe, North America and South America. There are two other breweries in Africa and Australia. Sorry to debunk the rumour, but the Guinness you get in the US, although perhaps not as fresh as that in Dublin, is the same stuff, and is not a different recipe brewed in Canada or elsewhere.
The tour finishes with a panoramic view atop the brewery where you can enjoy a complimentary pint.
