Take your wine drinking to a new level with this cup designed to be seasoned over time!  The red wine stains the unglazed clay and over time builds up colour and flavour in the cup.  When you are done drinking and there is a wee bit of wine in the bottom you just can't get out, it will soak in and season your cup.
 
You can wash the cup of course, but most people will just wipe off the lip.  There are four colours of lips, so you can have your favourite colour and someone else in your house can have their favourite colour.  You will know whose cup is whose!
