We left our recent tasting in Bierzo buzzing with excitement. You need a great deal of passion, energy and grit to succeed in these remote hills; fortunately, these are qualities Gregory Pérez has in spades. You might also have to be a little bit crazy—something Pérez, too, knows a bit about. Looking back through the years, his wines have always been engaging and delicious. Yet where his earlier releases could be described, in the best sense, as a touch wild (and we loved them for it), over the years, he has figured out how to tame the mountain. Today his wines are sleeker and more precise while losing none of their distinctive highland personality and rocky, mineral charm. Pérez’s work in his vineyards has always been exhaustive. His vines are old and grow above 500-600 metres, making them among the highest in Bierzo. The rugged, undulating vineyards are managed by hand, often using an ox-drawn plough. Fortunately, these days Pérez can count on the help of two young vignerons, Andrés and Jonathan—who, incidentally, bears a resemblance to a young Bob Dylan—which allows him to spend more time fine-tuning the winemaking at his newish, spacious winery in San Juan de Carracedelo.Pérez has been using his time well. The white wines are the most obvious beneficiary; these great-value Godello-based releases have more focus, fine lines and mineral energy than ever before. On the red side, Pérez’s Mencía wines are more refined and showcase mouth-watering chalky structures and floral prettiness to complement their succulent, herb- and soil-tinged fruit. Finally, there is Pérez’s strikingly pretty, floral and berry-scented Estaladiña, superbly crafted from a variety that may or may not be related to France’s Trousseau. It’s a tug-at-your-heartstrings red from a beacon of Bierzo’s viticultural renaissance.
