NOTHING on the planet smells like freshly picked hops.
The small flower cones grow on vines (or, more accurately, bines, like string beans), and their sticky, oily resins provide the essential bitterness that balances the sweetness of malt. Without hops, beer would taste like something you might drink through a straw. When you are 14.
Bitterness aside, though, it's aroma that makes hops such a wonderful specimen of nature.
Freshly plucked and crushed between your fingers, they explode with a complex bouquet that may be fruity or spicy or gardenlike, depending on variety. Chinook hops are reminiscent of pine needles baking under noon sun. Saaz are earthy, like the aroma of hard-earned sweat after a day of kneading your garden. Hallertau are at once floral and citrusy, like fresh dew on the leaves of a lemon tree.
