It sounds simple enough, I mean you wash juice and milk glasses all the time, what could be so special about washing a wine glass? Truth is, wine glasses do need just a bit more care in the washing arena. Keep in mind that the liquid in the wine glass is typically a bit pricier than your jug of milk or orange juice, so the extra measures to ensure a clean glass could be viewed as merely protecting your investment.
To Soap or Not to Soap
There is some debate in the wine world about using dish soap to wash wine glasses. It's true that residual detergents can impact the smell and taste of a wine, so if the surfactants you use tend to be particularly sticky and problematic to rinse out thoroughly, then you might consider forgoing the soap and rinsing with hot water only or employing a spray or two of hydrogen peroxide and then rinsing the glass.
Washing Phase To wash a wine glass you can take one of several approaches:
The Rinser Method
As easy as it sounds, just rinse, rinse and triple rinse your wine glasses with hot water. Make sure that all of the residual wine is removed and allow glasses to air dry, turned upside down on a clean towel.
The Washer Method
Using a very mild detergent, sparingly add a drop to each glass and sponge the soap around to remove all wine stain. Then rinse the heck out of the glass. Soap residue left on your wine glass will interfere with the flavor and aroma of wine. Keep in mind that there are several wine glass specific cleaning products out there designed for use on wine glasses that range from cheap to the more expensive Riedel and Spiegelaus glasses. Stemshine
is a cleaner designed specifically for wine glasses and can handle lipstick smudges, red wine residue and sediments along with oily fingerprints on wine glasses quite well.
The Soda Method
Often reserved for delicate crystal glasses, washing soda (or baking soda if you are hard pressed) will gently clean the glass and absorb residual wine. Washing soda is available in most grocery stores in the detergent section. Remember that crystal is much more porous than typical glass and is more likely to absorb odors from its surroundings, be that storage companions - like a cupboard full of coffee or cleaning detergents used in the process.
Wine glasses that have shorter stems and that are not made from crystal are ideal candidates for the good old dishwasher. Just use a bit less detergent than you would for a normal, full load and don't set the wash cycle on "heat dry," so that you avoid baking on detergent that has not washed clean. Once the cycle is complete, immediately remove glasses and hand dry with a lint-free dish towel.
The method may vary, but the result should be the same - a clean glass of wine, every time.
