OK, so we're going to state the bleeding obvious here. It's pretty much essential to have glassware handy if you are going to drink wine. We've known the odd WineMarketeer to get a bit loose and take a slug of some wine or other straight from the bottle, but modern practice says to use a receptacle of some kind to drink fermented grape juice from. Again, it seems a little obvious, but glass is really the ideal. We know that Aunt Ida gave you those hard plastic Champagne flutes she personally bedazzled with diamantes shaped into love hearts, but ideally glass (or crystal) goes with wine.
So we've covered the basics, now onto step two. If you've got your glasses ready, its time to make sure they're clean. Not a wipe with a dirty dishrag, a proper rinse and polish is preferable – that way you can get the most pure, unadulterated expression of the wine in your glass, not last night's chicken Parma smeared around your glass rim.
Step three is where things get complex. If you have a range of glass wear, certain wines suit certain shapes of glass. Sounds unusual, but truth is the profile of grape varieties vary, so glassware for varieties can vary too! Big, bold red wines made from Shiraz or Cabernet are great in big, tall glasses. Delicate Riesling and Sauvignon Blancs are best from smaller, tighter rimmed glassware. Champagne requires flutes, while Chardonnay and Pinot Noir go well in wide bowled glasses. Professional stemware is available for grape varieties, with Riedel, Spiegelau and Schott-Zwiesel some of the better know brands. Glasses with stems are better than the current vogue of using stemless ones. Fingers can leave food smears on glasses and hands warm up the wine in the glass, hence a stem solves both problems.
Glassware is simple. Proper glass. Proper clean. Proper shape.
