Printed works published in many countries in the form of journals, brochures, magazines, books, catalogues, magazines, prospectuses and tasting notes, but increasingly also in the form of online portals in which wines, sparkling wines and spirits are assessed in terms of quality and described verbally, and producers are also rated. Online applications such as websites and various social media platforms (blogs, YouTube clips), in which the results are immediately put online and are thus far more up-to-date, are becoming increasingly important
The evaluation is carried out by professional tasters or wine critics in the form of points, such as the 20-point or 100-point system, and also with symbols such as bottles, grapes, stars and glasses, in which case the maximum number is usually between three and five. The works listed in the following have different concepts and contents, but what they all have in common is that wines are described (wine talk) and judged and evaluated (wine rating). The boundaries between wine journal/magazine with a wine rating section and "real" wine guide with a focus on producers with their wines are fluid. Some are only available on paper, most of them also have online portals. The leading European internet platform on wine is wein.plus. The wine guide contains over 130,000 wines rated and described according to the 100-point system; the wine encyclopaedia includes over 23,000 keywords.
