If you've been wondering about the odd cup in the background of these pages, this should explain a bit. The two primary traditional drinking cups for mead are mazers and mether cups. Mazers are more or less big bowls. Mether cups are like what you see on these pages.
The basic mether cup is square at the top and round at the bottom with four handles. It's a bit tricky to drink out of at first.
For our wedding, Abby and I wanted a pair of cups for toasting. It turns out that they're very hard to find. Edward at the Heartwood Gallery in Fayetteville, Arkansas made a pair for us. We were able to toast our wedding with mead made with rose pedals from the vines where we live and out of traditional mether cups. It was quite a treat.
