Wine tasting in Chiang Mai: a guide to Thailand's most surprising wine country

The drive to Mae On takes forty minutes on a road that earns its reputation slowly. You leave the ring roads behind, pass the last 7-Eleven, and the valley opens up around you: forested hills, a river running alongside the tarmac, the temperature dropping a degree or two as the elevation climbs. At 410 metres, a gate appears on the left. Behind it are vines.

They look exactly as you would expect vines to look. Low, trained along wire, surrounded by forest and a silence that the city does not offer. What they should not look like, according to a century of received wisdom about where wine grapes can grow, is viable. Thailand sits below the Tropic of Cancer. Wine geography, as most people understand it, stops well before this latitude.

That understanding is being revised, and Mae On is one of the places revising it.

Growing grapes where the textbook says you cannot

The standard rule places vineyards between 30 and 50 degrees latitude north and south. France, Italy, California, New Zealand all sit inside that band. Thailand operates at 13 degrees north, a position that serious viticulturists dismissed for decades, and not without reason. Tropical heat strips acidity from grapes before harvest. Constant rainfall brings fungal pressure. Without a cold winter, vines do not go dormant, and dormancy is what resets the growing cycle.

The more interesting fact is not the obstacle. It is what winemakers did with it. Thai producers, working first in the Khao Yai region northeast of Bangkok, worked out that two growing cycles per year are possible if you simulate dormancy through aggressive post-harvest pruning rather than waiting for a winter that will never come. Time those cycles correctly and the 120 to 130 days of stable, dry-season conditions needed for grapes to ripen falls within the October-to-March window. The wet months become the vegetative period. The dry months become the harvest season. It is farming turned inside out relative to European convention, and it works.

What makes the northern highlands specifically interesting is altitude. Every 400 metres of elevation drops ambient temperature by three to four degrees Celsius. In January, the coolest month in Mae On, night temperatures reach 15°C while daytime highs sit around 29°C. That diurnal swing is the mechanism that preserves acidity in the berry through to harvest. Without it, you get flat, sweet fruit. With it, you get a wine with some structural tension in the glass. The distinction matters as much here as it does in any wine region.

This approach to growing wine at tropical latitudes has a name now: new latitude wines, a category that includes producers in Kenya, Brazil and Indonesia alongside Thailand. The term acknowledges something that was not acknowledged twenty years ago: the classical latitudes are not the only latitudes, they are simply the ones that were figured out first.

Why the timing has shifted

The structural change that opened Thailand's wine market to most visitors happened in January 2024, when the Thai Cabinet eliminated import duties on wine that had previously run at 54 to 60 percent of declared value, and cut the excise tax from 10 percent to five percent. The USDA Foreign Agricultural Service estimated the combined effect would reduce retail wine prices by 35 to 40 percent. A Kasetsart University study found a 300 percent increase in consumption of wines in the 3,000 to 5,000 baht range within twelve months. The market did not gradually warm to wine. It accelerated.

The wine culture that followed is more interesting than the consumption data suggests. Wine Enthusiast's March 2025 feature on Thailand described a Bangkok scene driven by younger drinkers who want to understand what is in the glass rather than pay for the label. A sommelier at Riedel Bangkok noted the expansion of hospitality options in Chiang Mai as a driver of that curiosity moving north. Estate-based wine tourism needs exactly this kind of visitor: someone who will walk vines, ask questions, and stay for dinner.

Mae On: the ground beneath the vines

Mae On is not on most wine maps. Locals know it for the San Kamphaeng hot springs and the Crazy Horse Buttress, a limestone cliff that draws climbers from across Southeast Asia. The viticulture here is newer than both, and it draws on geology that makes the valley more interesting than its relative obscurity suggests.

Mae On sits on ancient tectonic fault lines, with geothermal activity surfacing at the hot springs nearby. The bedrock is predominantly granitic, carrying elevated potassium levels that support sugar development as grapes ripen. Soil analysis at the Skugga Estate vineyard site revealed loamy clay with a cation exchange capacity indicating efficient nutrient retention and release, and organic matter content of two to four percent. That last figure is worth pausing on: organic matter in the two to four percent range is considered favourable in most wine-producing regions. It is not common in tropical agricultural soils.

The surrounding forest moderates wind and holds humidity at workable levels. At 410 metres, the microclimate is measurably cooler than the Chiang Mai valley floor below. None of these conditions were discovered after the vines were planted. They were the reason the vines were planted here.

Skugga Estate: what you actually encounter

Skugga Estate Vineyard is the primary wine tasting address in Chiang Mai. The vineyard was planted in 2025, which means the vines are young and the estate-grown wine programme is still developing. While that programme matures, the wines poured at Skugga are made in partnership with a boutique winery in the Barossa and Eden Valley in South Australia. The estate is open about this. The wines are chosen to reflect the balance the viticulture team is working toward, not to substitute for what the Mae On terroir will eventually produce.

The tasting list currently includes a red built around soft tannins and red fruit with a thread of spice that does not overwhelm the glass, and a Prosecco-style sparkling that opens with green apple and white peach. The range is not extensive, which is the right call at this stage. A long list with a young programme is a distraction. A short list with clear intention is an argument.

The varietal choices being developed in the vineyard are worth understanding before you visit. Colombard, a white grape with genetic roots in Gouais Blanc and Chenin Blanc, loses malic acid more slowly under heat stress than most white varieties. In a climate where heat is the primary threat to white wine quality, that biochemical stubbornness is not a minor advantage. Shiraz is among the reds being developed. At this elevation, with cool nights and managed canopy, the fruit does not raisinate. The volcanic substrate of Mae On contributes a mineral character that hot, low-elevation Shiraz sites rarely achieve.

Visitors who have been guided through the tasting by the estate team have noted the quality of the explanation. One TripAdvisor reviewer specifically credited Khun Ash's wine presentation as a reason the visit worked. That kind of guided context is what separates a wine tasting at an estate from a glass at a hotel bar. The estate's private vineyard tour and paired tasting runs to six wines with cellar access and chocolate pairings. For a first visit, that is the format to book.

The chocolate pairing is not a gimmick. Skugga's bean-to-bar programme uses single-origin cacao fermented and stone-ground at the farm 1.5 kilometres away. The pairing works because both the wine and the chocolate are made from raw agricultural material grown in the same valley system. There is a shared bitterness to the cacao and a shared earthiness to the red wines that the estate team have clearly thought about.

Beyond the tasting format, the vineyard events programme includes the underground wine cellar for evening sessions, the upstairs fine dining restaurant running 12-course degustation menus with pairings, and a downstairs bistro for visitors who want the estate without a full seated menu. The estate also produces gins and small-batch spirits matched to local botanicals, which matters if you are visiting with someone who does not drink wine.

Opening hours: Tuesday through Sunday, 10:00 to 20:00 on weekdays, until 22:00 Friday through Sunday. Book ahead for fine dining and group visits.

The farm and the full day

The Skugga Farm is a separate property 1.5 kilometres from the vineyard. Entry is free. The coffee roastery, chocolate lab, tea bar and classic car gallery are all there. A morning on the farm and an afternoon at the vineyard is a full day without repetition: the farm is about craft and production, the vineyard is about the table and the glass. The two properties share an aesthetic and a pace but serve different purposes.

Corporate groups use the estate for structured programmes across both properties. The Festival Hall at the vineyard seats 150 for a dinner and accommodates up to 400 standing. For groups who want to combine a destination event with wine, the infrastructure at Skugga is built for it rather than adapted to it.

The wider Chiang Mai wine scene

Skugga is the only address in Chiang Mai built around an active vineyard. For wine without the estate, Cape Dutch Wine Cafe operates in the city, focusing entirely on South African producers averaging 95 critic points, with several names appearing in Tim Atkin's 2025 report on the Cape. It is a specific list run by people who know what they are doing.

Monsoon Valley has operated in Chiang Mai longer than anyone. Its main production is at Hua Hin Hills, but the Chiang Mai vineyard is part of the same operation that built the Thai wine industry's commercial foundation over the past two decades. For historical context on what this industry has actually constructed, it is the reference point.

When to go and why now is the right answer

The Skugga vines are young. The first estate-grown vintages are some years away. That is, genuinely, the best argument for visiting now rather than later.

What the estate offers in this period is access to a wine programme being built in real time: the soil science, the varietal decisions, the reasoning behind why Colombard and Shiraz rather than something more familiar, the evidence that Mae On is a serious terroir rather than a novelty location. In five years that story will be told in retrospect. Right now you can walk it while it is still being written, which is a different kind of experience and, for anyone interested in wine rather than just the consumption of it, a better one.
