Gaze down into the liquid or through the sides of the glass with slightly defocussed eyes. Ask a question about what to expect in the year to come and wait to see if any visions come to you. You might see shapes, patterns or pictures within the glass, or you might get some other psychic impression of what lies ahead. When you've finished scrying, enjoy your wine!
I hope you have a happy New Year!
