Term for sexual reproduction in plants as well as in vines. It takes place during flowering through fertilisation and the subsequent sowing and rearing of grape seeds. Due to the heterozygous nature of the vine, however, the offspring always differ from the original vine. This fact is utilised when breeding new grape varieties. However, if you want genetically identical offspring (clones) for the purpose of creating a new vineyard, only vegetative propagation (asexual) can be considered, which is carried out professionally by vine nurseries. See also under breeding.

The Wine lexicon helps me to keep up to date and refresh my knowledge. Thank you for this Lexicon that will never end in terms of topicality! That's what makes it so exciting to come back often.
