Every winter for St. Patrick's Day, I soak oak chips in Irish whiskey, then brew a stout, and condition the beer on the oak chips. We use the same recipe every year, same grain and hop bill as River Horse's Craic, except Craic only uses Jameson barrels and they add vanilla. We leave out the vanilla and use better whiskey, a different one every year.
Last night I began soaking the oak chips, so I finished off the last of the whiskey used in our 2020 batch, Writer's Tears, and tried the whiskey we're using for our 2021 batch, Dingle. I'm not an expert on reviewing whiskey, but I can at least say that Writer's Tears did have a very nice taste but was a bit harsh. Dingle is smoother but as someone who isn't really into wine, the flavor imparted from sherry and port casks is more prominent than I prefer.
I also picked up a bottle of Ardbeg Corryvreckan, haven't tried it yet though.
