ECOtanka Double Walled Wine Cup 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 Wine Cup 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 Double Walled Wine Cup is double walled is made of 304 stainless steel on the outside and inside. 

The ECOtanka Double Walled Wine Cup is suitable for most drinks both hot and cold due to is 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 Double Walled Wine Cup inner coating has been tested for BPA, BPS and other chemicals from an independent testing lab, see below for the test report.

Inner Ceramic Coating:

​​​​​​​The ECOtanka Double Walled Wine Cup has been coated on the inside with an advanced food-grade ceramic coating that has been fully tested.  The Ceramic Coating adds a lot of extra benefits to the cup, with one standout benefit being the ability to have red wine in a stainless steel cup without losing the flavour and quality.   The inner coating also stops the heat transfer going to the outside layer which allows the cup to be used with hot drinks. 

ECOtanka Bamboo & 304 Stainless Steel Lid

This lid is made from sustainable bamboo, 304 18/8 stainless steel with a German quality silicone seal.

The bamboo lid is ideal for keeping insects and other air bound particles out of your wine or any other drinks in the hot climates, it also blocks the light so it will keep your drink fresher and cooler for longer. The lid is designed to complement the cup and is not designed as an airtight, spill-proof lid.

Due to the bamboo, it is recommended for cleaning purposes you hand wash and dry quickly.
