My HBS (Home Brew Mart) has 4 oz tasters of various HB's on tap. The two different Simcoe brews both tasted very much like grapefruit peels to me. One was a rye, one was supposed to be ginger ale. In both, the grapefuit aftertaste overpowered the other flavors- to my palate. It was educational to me to see how much a hop can flavor the brew.
