I chose these with a mind to the season. They are generally light- to medium-weight wines with an eye to freshness. Wine’s first duty is to refresh. In the added dimensions lies the value.

Monastero Suore Cistercensi Lazio Bianco Coenobium 2014, $19.99

This is a rare Lazio white with great character, a blend of trebbiano, malvasia and verdicchio. The grapes are grown by Cistercian nuns just north of Rome and made into wine under the supervision of Giampiero Bea of the great Umbrian producer Paolo Bea. It’s redolent of apples, herbs, citrus and volcanic soils, and has just the slightest pleasant tannic rasp, courtesy of longer-than-usual maceration with the grape skins. (Rosenthal Wine Merchant, New York)

Ronchi di Cialla Colli Orientali del Friuli Ribolla Gialla 2014, $19.99

Ribolla gialla is one of the indigenous grapes of the Friuli-Venezia Giulia region in northeastern Italy. This is a straightforward version compared with some of the vanguard wines made in the region, but it’s delicious, with flavors of nuts, flowers and tropical citrus fruits along with mineral undertones. (Soilair Selection, New York)

Ravines Finger Lakes Dry Riesling 2014, $17.99

Riesling has been a great success story in the Finger Lakes, and though it’s not the only winner in the region, it’s been by far the dominant grape there. Year in and year out, Ravines’s riesling has been one of my favorites. It’s absolutely refreshing, with earthy, citrus and wet stone flavors. If you like this, try the Ravines Argetsinger Vineyard riesling, a firmer, deeper single-vineyard version.

Domaine Michel Brégeon par Frédéric Lailler Muscadet Sèvre et Maine Sur Lie 2013, $17.99

Muscadet is perennially a great value, especially from Brégeon, an under-the-radar producer that always makes some of the more interesting wines in the region. This is characteristically fresh and tangy, with flavors of citrus, herbs and chamomile and a grainy, minerally depth that comes from aging on the lees, the remnants of yeast after fermentation. (Kermit Lynch Wine Merchant, Berkeley, Calif.)

Guímaro Ribeira Sacra Blanco 2014, $19.99

Ribeira Sacra in the eastern Galicia region of Spain, where the vineyards rise at harrowing angles from the rivers, is best known for its reds made from the mencía grape. But the whites, like this one from Guímaro, made with godello, can be superb. This is refreshing, harmonious and a touch exotic, with flavors of citrus, flowers, herbs and stone fruits.
