Keeper's Heart Whiskey, produced by O'Shaughnessy Distilling Co. in Minneapolis, Minnesota, is a unique blend that marries Irish and American whiskey-making traditions. Founded by cousins Patrick and Michael O'Shaughnessy, the distillery embodies their family motto, "Fugit Hora" ("The Hour Flies"), emphasizing the importance of cherishing moments with loved ones. The distillery features three copper pot stills and spans over 15,000 square feet dedicated to the whiskey-making process.

It also houses a restaurant and bar, offering shared spaces for guests to enjoy food and signature cocktails. Master Distiller Brian Nation, formerly of Jameson, Redbreast, and Midleton, brings his expertise to Keeper's Heart, crafting whiskeys that blend the smoothness of Irish whiskey with the boldness of American styles.
