The "article" has no references. Despite making claims like:
Traditionell werden die Weinflaschen liegend gelagert. Allerdings haben zahlreiche Untersuchungen in den letzten Jahren gezeigt, dass eine stehende Lagerung deutliche Vorteile hat.
or in English
Traditionally, the wine bottles are stored horizontally. However, numerous studies in recent years have shown that standing storage has clear advantages.
Really? What studies? Where? In what objective journal? Why not reference them if they exist? Were there any contradictory studies showing the opposite? I would love to read such journal articles. To get more real facts. But, they are not referenced.... What a pity.
In short, without actual references this web page means little. Without references, it seems yet another opinion, avoiding risking an actual intellectual debate with facts. As anyone can say anything without a reference and make its sound "official". And some people might believe it.
Side note: the two links at the bottom of the page go to 404 page not found errors. Kind of says it all.
