The shape of a grape (grape or table grape) basically has two different variants: a shouldered grape in the shape of a wedge and an unshouldered grape in the shape of a roller. This is often a typical morphological characteristic of a grape variety, but many varieties also have both forms or mixed forms; even on a single vine, on which there are always several grapes. Examples are Muscat Blanc, Tempranillo and Welschriesling. Many varieties are also named after grape shapes, often in resemblance to animals or plants (see last paragraph).
In the shouldered wedge shape, this is expressed at the top with more or less protruding "shoulders". This can be pronounced on both sides (in the example Cabernet Sauvignon, Sangiovese and Sultana) or only on one side (in the example Riesling).
The wein.plus encyclopaedia is a comprehensive, well-researched reference work. Available anytime and anywhere, it has become an indispensable part of teaching, used by students and myself alike. Highly recommended!Dominik Trick
