Where Alto Adige Is (and Why the Signs Are in German)
Alto Adige is Italy's northernmost wine region. Wine Enthusiast describes it as wedged between Austria and Switzerland in the Dolomite mountains. The main city is Bolzano, and the vineyards run along the valleys of the Adige River and up the slopes on either side.
It doesn't feel like the Italy on postcards. The region was part of the Austro-Hungarian Empire until after World War I and has been part of Italy since 1919. About 70% of people there speak German. That's why it has two names, Alto Adige in Italian and Südtirol in German, and why you'll often see both on a wine label. Think apple strudel and espresso in the same café.
It's also small. The regional wine consortium counts about 5,860 hectares of vineyards, farmed by 4,800 growers. That's a little over 14,000 acres, which makes it one of Italy's smallest wine regions. Most of those growers own tiny plots and tend them by hand.
What Mountains Do to a White Wine
Here's the whole explanation, in two parts.
Warm days ripen the grapes. Alto Adige is in the Alps, but it isn't cold. The mountains to the north block the harsh weather, and warm air flows up from Lake Garda and the Mediterranean to the south. The region gets about 300 days of sun a year.
Cold nights keep them fresh. After dark, cool air drops down from the peaks and the temperature falls fast. In July, the average goes from about 86°F in the afternoon to 61°F at night. Wine Enthusiast explains why that matters: cool nights slow ripening and preserve aromas and natural acidity, both of which translate into freshness.
Acidity is the part of a wine that makes your mouth water. In a hot place with warm nights, grapes lose it as they ripen, and the wine can taste flat. In Alto Adige, the grapes get ripe and keep their acidity. That's what you taste in a good wine from here: real fruit and a crisp finish in the same sip.
The vineyards themselves cover a big range. They sit anywhere from 200 to 1,000 meters above sea level, or roughly 650 to 3,300 feet. Growers match the grape to the height. Varieties that like warmth go in the valleys and on the lower slopes. Varieties that like it cool go higher up.
A Lot of Different Ground in One Valley
The soil changes as often as the altitude. The consortium counts well over 150 different types of rock under the region's vineyards. There's volcanic porphyry around Bolzano. There's limestone and dolomite rock in the south. On the valley floors, there's gravel and sand left behind by rivers.
You don't need to remember any of that. The useful part is this: with so many combinations of soil, height, and sun, growers here can find the right spot for each grape. That's a big reason such a small region makes so many kinds of wine well.
What Alto Adige Is Known For
About 65% of the wine is white. Around 20 grape varieties are grown here. These are the ones to know.
- Pinot Grigio. It covers about 12% of the region's vineyards. Wine Enthusiast says Pinot Grigios from here rank among the best in Italy, with more concentration than those from the plains.
- Gewürztraminer. Intensely floral and aromatic. The grape appears to take its name from the local village of Tramin.
- Pinot Bianco and Chardonnay. Clean, fresh whites with a little more body.
- Schiava. A native red, light and easy to drink. Locals call it Vernatsch.
- Lagrein. The other native red, darker and fuller.
One more number worth knowing: over 96% of the region's vineyards are under DOC protection, which the consortium says is the highest share in all of Italy. In plain terms, almost everything grown here is held to a regional standard.
Castelfeder, and What Three Generations Buys You
Luna Nuda isn't made in a factory with our name on the door. Our Pinot Grigio is made at Castelfeder, a family winery in the far south of Alto Adige.
Alfons Giovanett founded Castelfeder in 1969. His son Günther runs it today with his own children, Ivan and Ines. Ivan is the winemaker. That's three generations working the same valley. The family vinifies grapes from about 70 hectares of vineyards, and roughly 70% of those are white varieties.
What does that buy you? Mostly, knowledge you can't get any other way. After fifty-plus years, a family knows which rows ripen first, which plots handle a hot summer, and which ones to pick early. The winery says it handles even its smallest plots separately so each one gets what it needs. You taste that as consistency. The bottle you buy this year tastes like the one you liked last year.
Luna Nuda Pinot Grigio comes from estate vineyards in the Bassa Atesina, the warmer southern end of the valley. That's exactly where the regional consortium says Pinot Grigio does best. The grapes are picked by hand, fermented in stainless steel, and rested for four months before bottling, with no oak. The result is golden apple, citrus, and a clean mineral finish.
It's also been tested by people who don't know us. The 2024 vintage earned 92 points and a Gold Medal at the 2025 USA Wine Ratings.
And the name? Luna Nuda means “naked moon.” It's a nod to Alfons, who believed wine was best made under a full moon. We like the story. We like the wine more.
January in the Vineyard
Right now, in the middle of winter, the vines in Alto Adige are bare and dormant. It looks like nothing is happening. This is actually when next year's wine gets decided.
Winter is pruning season. Growers walk every row and cut each vine back by hand, leaving only a few buds. It's slow work, and it's a choice. As Wine Spectator puts it, pruning focuses the vine's energy on producing a smaller volume of the best grapes possible. Fewer buds means fewer bunches, and each one gets more of what the vine has to give.
You'll see two ways of training vines here. The traditional one is the pergola, where the vine is trained overhead on a wooden frame so the leaves form a kind of roof. The newer one is Guyot, where the vine grows along low wires in neat rows. Our Pinot Grigio vineyards use both.
Quick Answers

What does Alto Adige Pinot Grigio taste like?
Apple, pear, and citrus, with more fruit and texture than the lightest Pinot Grigios, and a fresh, mineral finish.
Why does wine from the mountains taste different?
Warm days ripen the grapes and cold nights preserve their acidity. The wine ends up with ripe fruit and a crisp finish at the same time.

No. They're neighbors and together form the region of Trentino-Alto Adige, but they're two separate provinces. Alto Adige is the northern, largely German-speaking one.
