The Right Glass: A Glass and Drinks Guide

It is a common myth that it’s best to wash stemmed drinking glasses by hand. A lot of people believe that dishwashers turn glasses cloudy, or can break wine glasses in the wash. This is a hangover (pun intended) from a time when dishwashers weren’t as sophisticated as they’ve become in recent years, and before products such as Finish® Quantum Dishwasher Detergents were introduced to prevent glass corrosion. Since all glasses are different however, they can’t be washed in the same way. The many different variations in shape, size and thickness need to be reflected in the approach you take, since the way you position, stack and order glasses will help ensure their safety and avoid breakages.  

Our simple guide below investigates the reasons why  there is so much variation in some of these drinking glasses, and also provides some tips on how to ensure they can be washed safely and effectively.

Wine Glasses

There are two types of wine glass: red wine glasses and white wine glasses. Red wine glasses have a broad and round bowl, and a short stem. By contrast, white wine glasses are longer and narrower. This is because a red requires more space to circulate and react with the air, smoothing out complex flavours, whereas a white requires a glass that inhibits oxidization in order to preserve the subtler nuanced flavours.

As with all drinking glasses it is important to load wine glasses onto the top rack, away from any other dishes. To accommodate the white wine glasses it may be necessary to lower the rack to make space for their longer stems, a feature available on many modern dishwashers. It is also important to ensure they are not touching each other, as this could cause them to crack as they knock together. Keep the clinking for the toasts!

Martini Glasses

The martini glass came about in the early 20th century, as an evolution of the cocktail glass. They were designed much like the wineglasses, to control oxidisation. The conical shape and obtuse profile of the bowl gives the gin maximum exposure to the air, which allows the flavours to open up and the complex botanicals to be discerned. One explanation takes a slightly different route however, claiming that the glasses came out of prohibition: if a speakeasy was raided, it only took a slight flick of the wrist to dispose of any incriminating liquid.

Martini or cocktail glasses need to be washed carefully since they have an even longer and more delicate stem than their wine counterparts, so lowering the top rack to create more space is a must. It’s also very important to make sure you space them out well to ensure they have enough space to move without making contact with any other objects.

Brandy Glasses

The short stem of the brandy glass combined with a large surface area means that the alcohol contained within starts to evaporate much more quickly. This combined with the sides curvature means that the bowl fills up with the brandy’s aroma, allowing you to fully experience the flavour.

Because of their design, brandy glasses can be washed similar to red wine glasses. There’s no need to lower the top rack, but as their low centre of gravity makes them prone to sliding around, be sure to give them enough space to avoid  knocking against other glasses in the dishwasher.

Crystal Glasses

Crystal glass was originally made by replacing the calcium content of glass with lead, and a piece has been found dating as far back as 1400BC.

When it comes to crystal glasses it’s best to check for washing instructions with the specific manufacturers. Every manufacture provides different dishwasher specifications for their glasses. Some may specify that their glasses are too thin for a dishwasher, whereas others say it is safe to wash on a cycle that keeps the temperature below 150 degrees. It’s important when washing crystal to use a mild detergent, and several leading crystal manufacturers recommend Finish detergent for dishwasher use.

So there you have it, now that you know what glass is what it’s time to invite round some family and friends to test them all out. Just make sure you enjoy these drinking glasses responsibly! Cheers!
