Byrrh, which is actually pronounced beer, is one of the better bitter aperitifs. It is definitely less bitter than many French bitters but its actually very good on it's own and maybe even better in cocktails. On the nose you get blueberries and prunes. The palate brings cherry, slight bitterness and blackberry, with the hint of red wine (not surprising since it has a wine base). The finish has some spice, no burn and decent length. For the price, Byrrh is a great value. If you want a bitter liqueur that leans heavy on the bitterness, such as Campari, look elsewhere, but as an aperitif (with a bit of ice and a citrus peel) you cant go wrong. I'm tempted to boost this to 4 but neat it doesnt offer much complexity. It's still worth seeking out in my book.
