Though it’s a centuries-old tradition, natural wine is having a new moment, as drinkers look for less-processed, better-for-you booze. The appeal of natural wine starts with the winemaking process, which involves minimal intervention.

“The philosophy tends to be not to manipulate (the wine), to let the grape stand for itself, and have the soil and terroir speak through the bottle,” explains Coly Den Haan, a sommelier and the owner of Vinovore, a Los Angeles-based shop specializing in products from female winemakers. (“Terroir” is a French termfor how an area’s climate, soil, and terrain influence a wine’s taste.)

How is natural wine made?

Natural wine starts with “organic biodynamic” farming practices with no pesticides, the use of native yeast for fermentation, and minimal to no-added sulfur, Den Haan says. Conventional wines often contain commercial yeast and sulfites, which act as a preservative and prevent oxidation. Natural wines also tend to be unfiltered and unfined, and do not contain added sugar, chemicals, or other elements.

Still, there’s no official certification process or specific designation for natural wine, however, Den Haan points out.

What differentiates natural wine from regular wine?

For conventional winemakers, the business of wine has led many to take “shortcuts” in the process, like using synthetic pesticides, hybrid grapes, cultured yeast, and additives to increase production and increase consistency, says Darren Scott, sommelier and general manager at Estate Wine Brokers.

The shortcuts have, in some cases, “stripped wine of its character, but at the same time, exponentially increased production and flooded the market with these sort of insipid wines that lack any sort of regional typicity or character,” he adds. Scott sees natural wine’s popularity as a reaction to the mass production, and compares natural and some conventional wines as “the difference between fast food and farm-to-table.”

Den Haan, meanwhile, links the growing interest in natural wine to people’s concern about where their food and drinks come from.

“Everything has its moment, and I think natural wine is having one,” she says. “I’m happy because I really believe in it—stylistically, for the planet, just the whole philosophy behind it. Minimal intervention. I just love that.”

Are natural wine and organic wine the same thing?

While most natural wines are organic, not all organic wines are natural. The term “organic” refers to the growing of the grapes, not the winemaking. Even if a winemaker uses organic grapes, they may manipulate the wine using additives or preservatives to get their desired result, Den Haan explains.

Some wines may also technically be organic, even if they aren’t labeled as such. Scott says many traditional family winemakers in the United States and Europe practice organic farming, but they may not go through the lengthy and costly certification process that would earn them an organic label.

What about natural wine’s alcohol content?

Natural wines tend to be lower in alcohol than other wines, Den Haan explains, because they have a lower sugar content and a purer alcohol forms from the fermentation. This also means natural wines are lower-carb.

Less alcohol and no added chemicals could also mean less of a hangover, says Den Haan.

What types of natural wine are there?

Natural wine comes in many different varieties: red, white, and rose. Some other common types are pet-nat and orange wines.

Pet-nat, or petillant-naturel, is a naturally sparkling wine created when the wine is bottled before being fermented. In traditional methods, sugar and yeast are added to still wine to create a second fermentation and the bubbles. Pet-nat can be made with many different grapes.

Orange wine is produced using white wine grapes that are fermented with their skin and seeds still attached. The process creates an orange-colored wine that can have a sour or nutty flavor.

What does natural wine taste like, and where can you buy it?

The range of styles of natural wine creates a mixed-bag when it comes to taste. Some may be “funky,” almost kombucha-like, while others are clean and well-polished, Den Haan explains. Natural wine offers a unique tasting experience, Scott adds.

“Be prepared for flavors you’ve never experienced in a wine before if you’ve never had a natural wine,” he says. “I’ve noticed that people are curious about them. They try them and they enjoy them precisely because they’re tasting flavors that they’ve never tasted before in a bottle of wine.”
