How Natural Wine Is Made in the Polish Jura
Good natural wine does not begin in the cellar, but between the rows of vines. That is where it is decided whether the fruit will be healthy, ripe and full of the character of the place. How is wine made the natural way? Above all, with attentiveness: to the soil, the weather, the plants and the rhythm of each vintage. The winemaker does not try to create an identical taste at any cost. His task is to guide well what nature brings.
In practice there is no single, official definition of natural wine. Most often it means wine from organically grown fruit, fermented spontaneously or with minimal use of selected yeasts, and then made with as few additives and interventions as possible. Each vineyard, however, makes its own decisions, depending on the condition of the fruit, the style of the wine and the course of the season.
Everything begins with living soil
A wine’s natural character is built long before harvest. In organic viticulture, no synthetic herbicides, artificial fertilisers or chemical plant protection products are used. Instead of quick fixes, what is needed is observation, mechanical work, careful training of the vines and responding to the weather.
Soil here is not merely a base for the roots. It is a living environment where microorganisms work, cover crops grow and water is stored. A well-tended vineyard strives for balance, not maximum yield. Fewer clusters on a vine often mean more concentrated fruit, with better acidity and a clearer aroma.
In the Polish Jura, the limestone bedrock, the airflow and the difference in temperature between day and night matter too. These are not details from a landscape brochure. They influence the pace of ripening, the freshness of the fruit and the style of the future wine. The same grape variety can taste completely different in different places, because the vine records the conditions of its particular site in the fruit.
Ripeness does not always mean a later harvest
The moment of harvest is one of the most important decisions of the whole year. The winemaker judges not only the sugar level in the berries, but also the acidity, the taste of the pulp, the ripeness of the seeds and the condition of the skins. He also checks the weather forecast. A few rainy days before harvest can change a great deal.
For wines made with minimal intervention, the quality of the fruit is especially important. If healthy, carefully selected grapes reach the press, there is no need later to rescue the wine in the cellar with heavy-handed treatments. The harvest is often done by hand, so damaged or unripe clusters can be rejected right there in the vineyard.
This is no shortcut. Manual work takes time and a team, and the weather does not always allow you to wait for the perfect day. Natural winemaking is not about passively leaving everything to chance. On the contrary – it demands very good organisation and quick, well-considered decisions.
How is natural wine made after the harvest?
Once the grapes arrive in the cellar, the stage begins in which the fruit gradually becomes wine. White varieties are most often destemmed and gently pressed. The juice is separated from the skins and then goes into a tank, where it can settle and clarify before fermentation. With red wines, the juice ferments together with the skins, because that is where the colour, part of the tannins and the aromas come from.
Rosé wines can be made through very brief contact between the juice and the dark skins. Sparkling wines require an additional stage, during which natural bubbles form in the wine. The technical details vary depending on the style, but the principle stays the same: do not cover up the quality of the fruit with an excess of additives.
Natural production often relies on the yeasts present on the grape skins and in the cellar environment. This is what is known as spontaneous fermentation. The yeasts transform the sugar in the must into alcohol, carbon dioxide and a wide palette of aromas. The process can be less predictable than fermentation led by selected yeasts, but it can give the wine greater complexity and a sense of authenticity.
Not every spontaneous fermentation runs the same way, however. Its pace depends on the temperature, the ripeness of the fruit and the activity of the yeasts. The winemaker tastes the wine regularly, measures its parameters and keeps the cellar scrupulously clean. Minimal intervention does not mean no control. It means using only those measures that protect quality and let the wine develop at its own pace.
Sulphur, filtration and the question of additives
Many simple slogans have grown up around natural wines, and they do not always reflect reality. One of them goes: natural means no sulphur. In fact, sulphites can also form in wine naturally during fermentation. Sulphur dioxide is also sometimes used in small quantities as protection against oxidation and unwanted microbial activity.
Does every natural wine have to be entirely free of added sulphites? No. For some winemakers this is an important principle; others use minimal doses when the stability of the wine requires it. The most honest approach is to speak plainly about the practice used, rather than promising that every bottle is identical and unchanging.
It is similar with filtration. A wine can be filtered lightly, heavily or not at all. Skipping filtration can preserve more texture and aroma, but sometimes leads to sediment or a slight haze. That is not automatically a fault. It is worth remembering, though, that being natural does not excuse a wine from being clean, fresh and pleasurable to drink.
Time spent maturing does its work
After fermentation, the wine needs rest. It can mature in steel tanks, barrels or other vessels, depending on the variety and the intended style. Steel helps preserve freshness and fruity character, while a barrel can bring structure, spicy notes and a softer texture. The point, however, is not to let the taste of wood dominate the wine.
During this time the yeast lees may remain in contact with the wine, adding depth. The winemaker watches the aromas develop and decides when the wine is ready for bottling. Some light white wines taste best young; others need several months, or a dozen or more, of quiet. The vintage, the variety and the course of fermentation matter more here than any rigid calendar.
The bottle does not end the process. After bottling, the wine continues to settle, particularly if it was not heavily filtered or stabilised. That is why it is worth storing it in a cool, shaded place and serving it at the right temperature. White and sparkling wines gain freshness when well chilled, while a red is best opened a little earlier so it can show its aroma.
Organic and natural – similar, but not the same
Organic certification concerns above all the way the grapes are grown, and certain rules of production. It is confirmation that the farm operates according to audited standards. At Winnica Jura, our organic viticulture is confirmed by the PL-EKO-05 certificate, which means regular inspections and concrete accountability for how we work in the vineyard.
The term “natural” refers more often to a winemaking philosophy: limiting intervention, respecting the fruit and accepting differences between vintages. An organic wine is therefore not automatically a natural wine, and a wine called natural does not always hold an organic certificate. For anyone choosing a bottle, the most important thing is to ask good questions: where do the grapes come from, how was the fermentation conducted, and does the producer speak openly about their work.
The best way to learn all this is not from a label, but over a glass and in conversation with the winemaker. During a tasting, try comparing a fresh white wine with a longer-matured red, or taste a sparkling wine and see how differently nature can express itself in each bottle. It is a simple way to choose wine consciously – wine that suits not only the meal, but also the moment you want to celebrate.
