Glasses should be appropriate to the type of wine served. As this is not always possible, the ideal is to acquire a set of red, sparkling and Port wine glasses. The glass should be clear, with no adornment, in order to facilitate observation. It should have thin rim and walls and a good stem. You should hold the stem of the glass, not letting your fingers touch the bowl (upper part of the glass). The glass should be big enough to allow swirling the wine without spilling it and it should have capacity to hold approximately 60 to 80 ml of wine (which will occupy about 1/3 of the glass).
When serving wine, the glass should be perfectly clean and with no traces of detergent. You should always change glasses when serving new wines, otherwise there will be a mixture of flavours.
Ideally, hand-wash the glasses and use no detergent at all. Then, let them drain upside down for a minute or two. Dry the glasses with a clean cloth and store them upright on a closed shelf, away from dust and bad smells.
