Rías Baixas is a Spanish appellation located along the Atlantic coast in Galicia. The entire region is divided into five subregions: Salnes Valley, O Rosal, Soutomaior, Ribeira do Ulla, and Condado do Tea. There are several permitted grape varieties, but Albariño prospers and dominates in the entire region.

Other permitted grapes that are sometimes used include Treixadura, Loureiro, Caiño Blanco, Torrontes, and Godello. The styles slightly differ depending on the subregion and the production, but most of the wines hail from the region are pale golden, fresh, and aromatic. 

Albariño is a white grape variety grown in northwest Spain (Galicia) and northwest Portugal (Monção and Melgaço) where it is used to make varietal white wines. Albariño wines are very light, fresh, crisp, with high acids and of a rich, floral, and aromatic character.

Its specific aromas often include white peach, apricot, melon, pineapple, mango, and honeysuckle with an underlying minerality. Albariño wines are very versatile when it comes to food pairing, with seafood being the most obvious choice, along with a variety of dishes from Chinese, Indian, and Thai cuisine.

Txakoli is a light and fresh, clean-tasting, slightly sparkling, and usually white Spanish wine that is mainly produced in the Basque Country, more precisely in the wine regions Getariako, Bizkaiko, and Alava. The wines are typically made from Hondarrabi Zuri grapes, and although regional expressions may slightly differ, Txakoli wines are low in alcohol and high in acidity, while they usually display crisp fruity notes reminiscent of apples and citrus.

The wines are best enjoyed chilled, and they are traditionally poured from a height, either from the bottle or the pitcher known as porrón, to leave the tiny bubbles intact. Because they are a perfect match to cured meat, seafood, olives, and local cheese, Txakoli wines are a staple at pintxos (tapas) bars throughout Basque.

Getariako Txakolina is a Spanish appellation from Basque Country (Gipuzkoa) that produces white Txakoli wines—crisp white wines that the entire Basque region is famous for. The wines are low in alcohol and typically lightly bubbly.

Most are made from the native Hondarrabi Zuri grapes. Getariako Txakolina is one of the three Txakoli appellations. The examples coming from this region usually have brighter acidity. They will also mostly have a mineral, saline note, because of the vicinity to the Cantabrian sea (Bay of Biscay).

These wines have low alcohol content, around 10%. 

This white grape variety probably originated in North Africa from where it was imported to the Iberian Peninsula, and today it is mainly known as the principal grape used in Rueda (DO), both in blends and as a varietal wine. The wines produced from Verdejo are typically light-bodied, fruit-forward, fresh, and lively, with well-balanced acidity that is accompanied by bright and herbaceous flavors of citrus, fruit, and fennel.

With age, some varieties may develop nutty almond flavors. Because of its character, Verdejo is great enjoyed on its own, but it is also a food-friendly wine, and while young Verdejo is an excellent accompaniment to grilled and fried seafood, vegetables, salads, and fresh cheese, aged varieties may match paella and heartier fish or meat dishes.

Godello is a Spanish grape variety that has recently risen in popularity after it had nearly gone extinct after the 1970s. The grape shows the best results in Valdeorras in Galicia, though it is planted in other Spanish regions, as well as Portugal.

The wines made from Godello are usually full-bodied and dense but remain bright and mineral. Their character may vary, and while those aged in steel tanks tend to be lighter and fruiter, oak-aged styles are more creamy and rich. Godello wines will typically include notes of citrus and white fruit, with accompanying nuances of honeysuckle and chamomile. 

Xarel·lo is a Spanish grape variety best known for its use in sparkling Cava, where it is used along with Macabeo and Parellada. It is a high-quality grape that provides power, body, and structure in Cava wines. It is the most planted variety in DO Penedès.

Apart from sparkling wines, the grape is used for dry white wines, both varietals and blends. Wines made from Xarel·lo are medium-bodied and aromatic, with good acidity and alcohol content. The aromas are reminiscent of citrus and stone fruit, and the wines will typically have herbal and mineral character. 

Palomino Fino is a Spanish grape variety that is mostly used in the production of sherry. Known as a high-yielding grape that produces mainly bland white wines that are low in acidity and sugar, the must from Palomino can oxidize quickly, which makes it ideal for the production of sherry—fortified and oxidized wines that hail from Jerez.

The grape is used in the production of various sherry styles, and it accounts for approximately 90% of sherry production. The first must is mostly used in the production of dry white wines such as Fino and Manzanilla, while the second pressing is usually made into darker and richer Oloroso. 

Airén is the most widely planted grape variety in Spain. This white-skinned grape is better known for its sturdiness, and though it was mainly used as a blending grape or in production of brandy and table wines, some winemakers have seen its potential in the production of crisp, good-quality varietals.

Wines made from Airén grapes are light and typically low in acidity, with fruity aromas reminiscent of green apples, pineapple, and citrus fruit, while the best examples will usually also display rose nuances. These easy-drinking wines usually have moderate acidity and perfectly pair with white fish and seafood.
