A special form of wine tasting and wine evaluation in which wines from different vintages of a single producer or winery (therefore also referred to as a château vertical) are usually compared with each other to determine the vintage influence on wine quality. The vineyard can also act as a representative for an entire growing region. Ideally, these are wines of the same "construction" (in terms of grape variety mix and style of v inification) and from the same vineyard. The "vertical" refers to the time axis (vintages) "from top to bottom". So it is not a matter of determining the quality differences between producers, but between vintages. Whether this takes the form of a blind tasting (then called a blind vertical) depends on the objective.
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.Dr. Edgar Müller
