The white grape variety originates from Spain. Synonyms are Tolociriana and Tolocirlana. According to DNA analyses carried out in 2013, it is a presumably natural cross between Garró(Mandón) x unknown variety. However, this is based on only 20 DNA markers (see Molecular genetics). Castallena Blanca was a parent of the varieties Godello, Gouveio Real, Praca, Tinto de Navalcarnero and Verdejo, which were created by presumably natural crosses. The variety used to be widespread in Castile-León; today it is grown in only small quantities in the Canary Islands. In 2016, one hectare of vineyard was designated (Kym Anderson statistics).
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.
