Remember that whole 14th century bit we told you about Kilkenny? Well, it applies to Smithwick's, too.
Both Smithwick's and Kilkenny were brewed on the site of a Franciscan abbey in Kilkenny, where monks had brewed since the 14th century. It wasn't until 1710 that John Smithwick and Richard Cole founded the brewery that it started producing the Irish Red Ale known and loved today. With lots of malt and a little hint of caramel, Smithwick's is almost still as it hits a drinker's tongue and smooth and light going down. While it feels almost devoid of carbonation, a pint of Smithwicks from a nitrogen tap can be as light and lovely as any stout and pairs nicely with a Guinness as a proper Black and Tan.
Though only 3.8% alcohol in Ireland, Smithwick's gets kicked up to 4.5% ABV in the states. If you're worried about where to find it, you obviously haven't been to a pub in a while. Smithwick's was bought by Guinness in 1965 and is part of the Diageo family. If you find one, chances are you'll find the other at a tap beside it.
