wine bordeaux heavy storage

NZZ Bellevue published a fascinating column this week by Peter Keller asking: What actually defines a heavy wine? Is it purely alcohol content? Or do grape variety, terroir and blend composition play an equally important role?

It’s a question we find ourselves thinking about every day.

What we see at Wine Storage every day

Our clients store everything. Light Pinot Gris from Alsace, elegant Burgundies, powerful Barolos, massive Amarones, Châteauneuf-du-Pape pushing 15 percent alcohol. And if there is one thing we have learned, it is this: the heavier the wine, the more demanding its storage requirements.

A heavy wine is not a simple product. It is an investment in time. It needs years, sometimes decades, to reach its full potential. An Amarone that is ready to drink today can reach a completely different dimension in ten years. But only if it is stored correctly.

That is where we come in.

Heavy wines demand stable conditions

What many wine lovers underestimate: heavy, tannin-rich wines are particularly sensitive to temperature fluctuations, light and vibration. A Barolo that survives a hot Swiss summer in a home cellar at 18 degrees is not the same wine as one stored consistently at 13 degrees.

In our wine storage facilities in Zurich, Basel, Lucerne, Zug, Winterthur and Bern, we maintain a constant 12 to 13.5 degrees and 65 to 70 percent humidity. Around the clock, throughout the year. Not because we are particularly fastidious, but because great wine deserves nothing less.

Because great wine needs time.

The question most collectors never ask themselves

Peter Keller’s column focuses on defining the heavy wine. We would add one more question: where are you storing your heavy wines right now?

Most wine lovers who come to us have the same story. They started buying wine. A few bottles at first. Then a case. Then another. At some point a bottle of Château Pétrus is sitting next to the washing machine, and a 2015 Barolo is fighting summer heat and humidity in a basement.

This is not a criticism. It is the story of almost every collector.

The moment when professional wine storage makes sense arrives earlier than most people think. Not at 500 bottles. But when the wines you are buying are worth more than the risk you are taking with improper storage.


The heavy wines our clients store most often

From our daily experience, these are the wines for which clients most frequently seek professional storage:

Bordeaux especially the great vintages, capable of ageing for decades and quick to deteriorate under poor conditions.

Barolo and Barbaresco from Piedmont, tannin-rich and long-lived, requiring patience and stability above all else.

Châteauneuf-du-Pape often high in alcohol, particularly sensitive to heat and temperature swings.

Amarone della Valpolicella one of Italy’s heaviest wines, with tannins and complexity that genuinely need time to integrate.

Swiss fine wines Pinot Noir from Graubünden or Merlot from Ticino develop far beyond expectation under the right conditions.

The question of what makes a wine heavy is more complex than it first appears. Alcohol alone is not a sufficient answer. Grape variety, terroir, vinification, maturity, tannin structure and extract all play a role together.

What we would add: a heavy wine is rarely made for immediate pleasure. It is made for the future. And the future starts with the right storage.
