What are the differences between natural, biodynamic and conventional wines, and what impact do they have on conservation?

With the evolution of winegrowing practices and growing consumer expectations, the terms natural, biodynamic and conventional wine are now commonly used... often without being fully understood. But these production methods don't just have an environmental or philosophical impact: they also influence wine stability and shelf life. Here's some technical information to help you understand the differences and adapt your wine cellar management accordingly.

1. Conventional wine: maximum stability, easy storage

So-called "conventional" wine refers to wine from traditional viticulture, which may use phytosanitary products (within regulatory thresholds), as well as oenological inputs during vinification.

Characteristics :

• Stabilized by filtration, fining and addition of sulfites.

• Technically stable wine, less sensitive to temperature or oxygen variations.

• Easy to store: well-defined ageing potential, suitable for conventional ageing cellars.

Ideal for long-term storage, provided standard conditions are respected: stable temperature (12-14°C), controlled humidity (60-75%), darkness and absence of vibration.

2. Biodynamic wine: living energy and precise preservation

Inspired by the work of Rudolf Steiner, biodynamics goes beyond organic farming. It is based on a holistic approach to the vineyard, integrating the rhythm of the stars, natural preparations and the balance of the soil.

Characteristics :

• Few or no synthetic inputs.

• Reduced but generally present doses of sulfur.

• Wine often unfiltered or only lightly filtered.

Impact on conservation:

• Better expression of terroir, but sometimes less microbiological stability.

• These wines are more sensitive tooxidation and temperature fluctuations.

For these wines, a high-performance cellar like the Climadiff aging cellars, with humidity control, constant temperature and anti-vibration system, is highly recommended.

3. Natural wine: authenticity, but potential instability

Vin nature (or natural wine) is the most radical in its approach: hand-harvesting, indigenous yeasts, no inputs (no sulfur, enzymes or stabilizers). Result: a wine with a free, sometimes unpredictable profile.

Characteristics:

• No filtration, no correction.

• Often cloudy, lively, evolving.

• Highly sensitive to oxygen, temperature, vibrations.

Storage:

• With the exception of a few mastered cuvées, these wines are not well suited to long ageing.

• They must be stored at a perfectly stable temperature (between 11 and 13°C), in complete darkness, with very little handling.

• The slightest fluctuation can irreversibly alter the wine (refermentation in the bottle, aromatic deviation).

To be avoided: cellars exposed to light, frequent opening of doors, rooms that are too cold or too hot.

4. What's the impact on your wine cellar management?

Conclusion

If your production philosophy influences your choice of wine, it should also guide your choice of storage equipment. Sulfur-free or low-stabilization wines require more precise wine cellars to guarantee their integrity. At Climadiffour aging and serving wine cellars incorporate the technologies needed to accommodate all types of wine, including the most fragile.
