ECOtanka Grail Cup 350ml has been designed and moulded to the shape of a wine glass, which makes this a comfortable style cup to hold. The inside layer follows the design of a wine glass with its curved oval shape bottom, unlike other similar products.
Our advanced food-grade ceramic coating on the inside of the Grail adds to your drinking pleasure and allows you to keep the taste and quality of your wine. Adding wine to any stainless steel finish can affect the taste and in some cases can completely change the quality and flavour.
The ECOtanka Grail is double-walled, is made of 304 stainless steel on the outside and inside.
The ECOtanka Grail is suitable for most drinks both hot and cold due to its double-wall design and ceramic coating giving it vacuum-like properties. This cup is ideal around the pool, camping, travelling, for a special occasion and is dishwasher safe.
The Grail inner coating has been tested for BPA, BPS and other chemicals from an independent testing lab, see below for the test report.
