We are an international group of WSET graduates brought together by a deep-rooted interest in wine, pursued through study, encounter and travel. Our diverse origin — both in provenance and occupation — is the base of a broad set of perspectives, experiences, of hesitations & interests. We rate and critique wines with a standard method (the SYS-TEM), based on form, content and character. Aware that the world does not need another wine rating scale, we begin this endeavour motivated by our shared enjoyment of the old grape ferment.
