White Duck Pottery wine cups - unglazed on inside

Pottery wine cups -Unglazed on the inside, it decants tannins and sulphides from your wine. No more headaches! Use and care- pour your wine, let it sit for a minute to allow the tannins and sulphides to settle to the bottom. They will cling to the rough texture of the clay as your drink. 
Rinse with tap water before pouring another cup of wine to get rid of the tannins and sulphides still clinging to the unglazed clay walls of the cup. Pick up cobourg, just south of hwy 401
