Soulo - wine by the glass Soulo is the brilliantly simple, convenient idea of sealing premium wine directly in an un-breakable glass. Wine lovers can now have delicious quality wine from an attractive eco-friendly single serve glass. Just peel back the foil seal and enjoy. Soulo has the look and feel of glass but is made of 100% recyclable PET plastic. This makes it perfect for all situations where glass is not welcome. It is ideal at a BBQ, by the pool or for all major sporting, cultural events, the hospitality and transportation sectors.
