Spain is doubtless a red-wine country, from Tempranillo and Garnacha to Menc\u00eda and beyond. But don\u2019t dismiss the country\u2019s white wines made from grapes ranging from Albari\u00f1o to Viura and Verdejo, Garnacha Blanca to Godello.\r\n\r\nIn recent years, Spanish wineries and winemakers have ramped up efforts to make cleaner, more consistent white wines that go beyond just being quaffable. The leaders of this movement hail largely from the R\u00edas Baixas, Rueda and Rioja regions.\r\n\r\nMy blind tastings since June of last year indicate that the Catalonian regions of Terra Alta and the Pened\u00e8s are also making positive strides with varietal bottlings of Garnacha Blanca and Xarel-lo, respectively.\r\n\r\nTo borrow an old wine-industry expression, one that could have been coined especially for Verdejo: Just chill it and kill it.\r\n\r\nMeanwhile, in Valdeorras and neighboring Bierzo, wines made from the local Godello grape have never been better.\r\n\r\nAs springtime comes into view, here\u2019s what\u2019s happening with Spain\u2019s top white wines.\r\n\r\n\r\nConsistency\u00a0\r\nAs a class, the most consistently pleasing and steady Spanish white wine is Albari\u00f1o produced in R\u00edas Baixas, located in the northwest corner of the country. Fresh, floral and easy to enjoy, Albari\u00f1o is Spain\u2019s top exported white, and for good reason. The wines are serious but uncomplicated, and they pair well with all types of seafood.\r\nRecommended White Wines from Rias Baixas\r\nVal do Sosego 2016 Albari\u00f1o (R\u00edas Baixas); $15, 90 points. Tight citrus peel and peach aromas show a leesy side on the nose. This excellent rendition of Albari\u00f1o feels round and juicy, but not sharp. Pleasing peach and melon flavors dry out and suggest white pepper on the finish. Saranty Imports. Best Buy.\r\n\r\nVionta 2016 Limited Release Albari\u00f1o (R\u00edas Baixas); $15, 90 points. Aromas of fresh-cut grass, wet stone and apple are mild on the nose. A round palate with zesty acidity is in full health, while flavors of apple, melon and pineapple last on the finish. Freixenet USA. Best Buy.\r\n\r\nMar de Frades 2016 Albari\u00f1o (R\u00edas Baixas); $25, 90 points. In this vintage, the wine itself is as catchy as Mar de Frades's signature blue bottle. Aromas of green melon, apple and lees are spot on for the variety. Flavors of pineapple and citrus finish with modest complexity carried by the presence of lees. Deutsch Family Wine and Spirits.\r\n\r\n\r\nNot New, But Improved\u00a0\r\nNoticeable improvements are occurring in Rioja, where a number of traditional and progressive wineries are barrel-fermenting both Viura and Tempranillo Blanco, with good-to-excellent results. These are high-acid whites that can absorb oak and age for decades. Serve these wines with fish, poultry or vegetable dishes.\r\nRecommended White Wines from Rioja\r\nRioja Vega 2014 Reserva Producci\u00f3n Limitada Tempranillo Blanco (Rioja); $45, 89 points. This barrel-fermented Tempranillo Blanco is low in intensity on the nose. However, in the mouth it is linear and shows strong acidity. Oxidized, old-school flavors of dry white fruits and oak finish long and mellow. Drink this classic white Rioja through 2020. Kobrand.\r\n\r\nSierra Cantabria 2015 Organza White (Rioja); $28, 88 points. Oak and spice notes are out front on the nose but not overpowering. This blend of Viura, Malvasia and Garnacha Blanca is medium in body, with a shot of bracing acidity. Wood-dominant flavors of spiced apple and resin carry the finish. Fine Estates From Spain.\r\n\r\nBodegas Faustino 2016 VII Viura (Rioja); $12, 86 points. Fresh aromas of green apple and melon meld with a note of yeast on the nose. A solid palate holds mild citrus and green-herb flavors that lead to the straightforward finish. Palm Bay International.\r\n\r\n\r\n\r\n\r\nPatio Poppers\u00a0\r\nIn Spain, the top-selling white wine is Verdejo from Rueda, a region located near the city of Valladolid, about 90 minutes northwest of Madrid. That\u2019s not because Verdejo delivers incredible quality, but because it\u2019s fresh, accessible and fits the bill when you just want a zesty white wine. With characteristics similar to those of Sauvignon Blanc, Verdejo is Spain\u2019s quintessential patio or tapas bar white wine. To borrow an old wine-industry expression: Just chill it and kill it.\r\nRecommended Verdejo from Rueda\r\nJorge Ord\u00f3\u00f1ez & Co. 2016 Nisia Old Vines Verdejo (Rueda); $17, 86 points. Mineral-driven on the nose, the palate of this Verdejo is citrusy in feel, with a grippy texture. Flavors of nectarine and peach are mild on a fresh finish. Fine Estates From Spain.\r\n\r\nBodegas Copaboca 2016 Finca Feroes Verdejo (Rueda); $6, 85 points. Apple and apricot aromas lead to a simple but healthy palate. Stone fruit and citrus flavors are ample but flatten out on a low-acid finish.\u00a0Magical Spirits. Best Buy.\r\n\r\nBotas de Barro 2016 Verdejo (Rueda); $15, 85 points. Mild stone-fruit aromas are quiet on the nose. This feels plump on the palate, with dry citrus flavors that are a touch green and bitter. Dangerous Import Group.\r\n\r\n\r\nBest of the Rest\u00a0\r\nIn the Catalonian region of Terra Alta, Garnacha Blanca reigns supreme when it comes to white wine. Not many years ago, the Garnacha Blancas from here were mostly heavy and oxidized, often with stalky aromas and flavors of wheat and wax. Today, white Garnacha from Terra Alta (and elsewhere in Catalonia) is being made in a cleaner, increasingly fruit-forward manner, sometimes with oak aging.\r\n\r\nAs for Godello, it\u2019s a white grape produced in Valdeorras (in eastern Galicia) that I\u2019ve often compared to Burgundian Chardonnay. Valdeorras boasts black-slate soils full of minerals, and is now seeing competition from nearby Bierzo, Spain\u2019s capital of Menc\u00eda. Versatile and often high in quality, Godellos from both regions are clear examples of the progress Spain is making with its white wines.\r\nRecommended White Wines from Other Regions\r\nEdet\u00e0ria 2016 Viaterra Garnacha Blanca (Terra Alta); $15, 87 points. Aromas of orange peel and tarragon are spunky and a little green on the nose. This fresh, lean Garnacha Blanca shows moderate acidity and short flavors of green melon and almond skins. A bit of saltiness is present on a dry finish. Ripe Wine Imports.\r\n\r\nAvancia 2016 Cuve\u00e9 de O Godello (Valdeorras); $18, 88 points. Mild but focused aromas of apple and lime are fresh and slightly minerally. This is round and easy on the palate, with controlled citric acidity. A simple flavor of orange finishes favorably but without complexity. Fine Estates From Spain.\r\n\r\nAbad Dom Bueno 2016 Godello (Bierzo); $24, 87 points. Yeasty white-fruit aromas carry the nose. In the mouth, this basic Godello is fleshy and pulpy. A mix of citrus and nectarine flavors holds steady on a fresh but simple finish. Frontier Wine Imports.
