If you're wondering whether the Graf Lantz Bierfilzl Felt Coasters stick to glasses, here's the scoop from what we've found. These coasters are made from 100% Merino wool, which is great at absorbing moisture. The material can soak up about 30% of its weight in moisture without feeling wet, so it's designed to keep glasses from sticking by reducing surface condensation.

Most folks in our research have pointed out that these coasters do a good job of handling moisture in general. However, if you're dealing with really cold or icy drinks, there can be a little twist. Some have noticed that the coasters might not be thick enough to handle all the moisture from iced drinks that sit out for a long time, which could lead to slight moisture seepage onto surfaces.

Another thing to keep in mind is that when the coasters get wet, they can sometimes stick to the bottom of a glass. So, you might experience a minor spill if you're not careful when lifting the glass—but this isn't something unique to Graf Lantz; it can happen with many fabric coasters when they're a bit too saturated.

On the upside, these coasters are praised for their craftsmanship and looks. They're lightweight and stylish, fitting in well with different décor styles. People have also mentioned how nice they are for drinks that aren't super cold or don't have much condensation.

In short, Graf Lantz Bierfilzl Felt Coasters blend style with functionality and particularly shine with drinks that don't cause heavy condensation. But if you often have drinks with lots of ice and need robust moisture handling, you might want to consider other options.

All in all, they're a great choice for adding a touch of style to your table as long as you keep their moisture management in mind.
