A special form of wine tasting in which the quality of wines from a particular growing region for a particular vintage is usually determined. The "horizontal" refers to the time axis. Naturally, these are wines from different producers, but they should have rudimentary similarities to enable an objective comparison. These are, for example, the same grape variety or blend of grape varieties (cuvée), the same ageing (e.g. barrique ageing), the same flavour (e.g. dry) and the same quality standard (e.g. known top producers or a similarly presumed class). Of course, differences in quality between producers can also be identified. However, the wines can just as well be a cross-section of different (presumed) qualities.
Using the encyclopaedia is not only time-saving, but also extremely convenient. What's more, the information is always up to date.
