'Rebsorte' (grape variety) is a compound noun made up of 'die Rebe' (grapevine) and 'die Sorte' (type, variety). The 's' in between is a linking element that connects the two words.

'die Rebe' and 'die Rebsorte' both belong to the topic of wine, but they do not mean the same thing. 'Rebe' is the plant on which grapes grow. 'Rebsorte' means the specific type of wine grape, for example a variety used for making wine. Learners may confuse the words because both begin with 'Reb-' and occur in viticulture. In practical terms: in the vineyard, the Rebe (grapevine) grows; on the label, you often see the Rebsorte (grape variety).
