I'll always love Bodegas Barbadillo, Solear Manzanilla Sanlucar de Barrameda Sherry, NV. From early wine epiphanies, like finding non-fruit but complicated nutty, yeasty, tea-like aromas in wine to discovering sherry as the ultimate ingredient in low-alcohol cocktails; it's an ever-applicable perennial favorite. It works well as a casual replacement to champagne as an aperitif, and enlivens sauces and dishes when used as a secret ingredient. It's a staple- thank goodness it's so affordable.
