Groslot / Grolleau is a varietal in the minority, but historical in Anjou, which gives the wine light tannins and luscious fruit. Grololo is a play on words coming from 'gros' meaning large and 'lolo' (a child's word) meaning breasts.
"Anyone who has the guts to market a wine like this Grololo deserves to have success. A jeu de mots (play on words) - it refers to the grape variety from which it's made. Groslot (or Grolleau) is a work horse variety that is widely planted in Anjou, mostly for the production of rosé wines. A wine for friends and family this is not to be taken too seriously as indeed it is not. Full of juicy fruit, slightly peppery on the nose and with light tannins it's what we call a 'vin de soif' and was formerly their wine served at family meals during harvest time.
The term Grololo is a used to describe 'big breasts' hence the label. Jo Pithon laughs out loud as he explains its meaning to us and while there may be the odd one amongst you who may feel this is a little inappropriate I'm afraid everyone around him laughed along too." - Letastingroom.com
