The oil-to-water ratio for the preparation of the emulsions was 20:80 (v/v) and commercial glycerol monostearate (GMS) was used as emulsifier at 6%, 8% and 10% (w/v). Two Hellenic wines, the white ‘Samena Golden’ from the grape variety ‘Muscat of Samos’ with 12.4% (v/v) ethanol and the red ‘Sangiovese Karipidis 2002’ from the grape variety ‘Sangiovese’ with 12.7% (v/v) ethanol were added at concentrations 5%, 10%, 20%, 50% and 100% (v/v) in deionised water to form the aqueous phase. Grapeseed oil (Henry Lamotte, Germany) was the oil phase in all cases. Mastic resin (Chios Mastiha Growers Association, Hellas) was added at concentrations 1%, 2% and 3% (w/v).
