I’m not particularly fond of pricey coasters. Large, heavy, non-absorbent discs or squares might look attractive, but my go-to options are the free ones I've collected from bars. These cardboard and plastic treasures are cost-effective (free), often quite absorbent, and easy to store. Plus, if you gather them during your travels, they give off the impression of a person leading an interesting life. The only downside? Some of the smoother coasters tend to cling to your glass.
While it’s not a big issue for hot drinks or cold cans and bottles, it becomes more of a problem when you’re sipping a cold drink from a flat-bottomed glass on a smooth coaster. The condensation creates surface tension, causing the damp glass to cling to the smooth surface of the coaster, forming a tiny vacuum. Eventually, more moisture drips down, breaking the seal and sending the coaster tumbling into your lap. It’s not a disaster, but it’s definitely annoying.
There are ways to deal with it. If this issue is bothering you at home, try using rougher, more absorbent coasters. I tend to “collect” textured cardboard promotional coasters whenever I see them, while Joel grabs upholstery and leather swatches, but any absorbent and slightly rough material works well. Avoid glazed ceramic, glass, or sleek plastic coasters—they’re the worst offenders. Slate, unglazed ceramic, natural stone, or even knitted coasters are much better at preventing the dreaded sticking. (You can also use a rough-bottomed glass; the issue arises when both surfaces are smooth.)
If you’re out and about and encounter a sticky coaster, simply sprinkle a little salt on it. The sodium chloride crystals will reduce the surface tension, allowing your glass to detach. Cocktail napkins are bound to cling, as they’re almost too absorbent. I lean into this and fold the napkin around the sides of my glass, essentially creating a portable coaster wherever I go. This trick is especially handy at weddings and social events where you're walking around with a drink. Not only will you avoid leaving a damp ring behind, but your hand will stay dry as well.
