KeepCup Brew Cork, Reusable Glass Tumbler with Natural Cork, Espresso Coffee Cup 6oz/227ml - Black

I love my KeepCup Brew Cork! The design is beautiful — the glass feels sturdy and premium, and the natural cork band adds a nice touch while keeping your hands cool. It’s the perfect size for coffee or tea, and it fits easily under most espresso machines and in car cup holders. The lid seals well, and it’s easy to clean and reuse every day. I really appreciate having a sustainable option that looks great and helps cut down on disposable cups. Perfect for anyone who loves their daily coffee and cares about the planet — practical, chic, and eco-friendly! ♻️✨

This is such a nice cup! It looks very clean and is the perfect size. I wish it was dishwasher safe but hand washing it isn’t too bad. I even had to buy one for my husband!

This is definitely for the aesthetic girls who like a neutral kind of coffee mug or coffee cup that goes with all of your outfits for on the go. I’ve only used this once so I can’t talk about durability just yet but so far so good. I appreciate the cork sleeve on the cup because the glass does get really hot so you definitely have to hold the glass around the cork. I love the look overall. The lid snaps on vs an screw top. I put some tea in here and so far so good.

Quality glass, coffee tasts great. my only wish is for them to make a metal cap that is air tight one day. Otherwise super product.

This cup is, first and foremost, very beautiful. Although this might seem unimportant, it makes drinking out of it much more enjoyable, and I remember to buy drinks in it more often (at least before COVID happened). I also like that, if you remove the plug, there's a hole big enough to insert a boba straw (which again lends itself to the "getting take-out beverages in it"), which is actually the main reason why I chose to buy this against its competitors. I also like that it is easy to repair, as Keep Cup sells the different parts on its website to prolong its lifespan. In terms of ethics, I like that Keep Cup is both a B Corp and part of 1% for the Planet. There are quite a few shortcomings in terms of functionality, but they don't bother me personally. If you care about any of the listed below, you should not buy this cup: - not thermally insulated, loses heat similarly to a ceramic mug - is a bit heavy - is also not super durable, since it's made of glass (I have been very careful to not drop it) - is NOT leak-proof, and will leak if the cup is placed on its side - the lid is a bit difficult to take off (would not recommend taking the lid off while there's a beverage inside as it would cause the liquid to splash) - must be hand-washed (DO NOT REMOVE THE CORK. In the beginning, whenever I washed the cup, I noticed that the cork would slip off. However, as time progressed, the cork band began to tighten) - the cork band is a little higher than where the hand would naturally rest (not conducive if you plan on drinking a lot of hot drinks) Overall, I have enjoyed my experience using the cup but I can see how its limited functionality could be a deal breaker to some.

I really do love this cup. Was turned to it by Lead Free Mama. The cork ring lets you hold onto the cup without having to touch the glass and get hot or cold or wet. The lid has a closure that works well, I’ve dropped it a few times and it doesn’t spill with the thing closed, also pretty durable. But please make sure the lid is on all the way. I went to pick it up in the car and only grabbed the lid and it wasn’t secure and spilled everywhere. Also, it says not to remove the cork ring, but if water gets trapped under there it can start growing green mold. It can get damp and be ok, and if you do have to remove it to clean the ring and under it, I found it’s easier if it’s damp, to come off or go back on. It is a cup made for someone who is willing to spend that little extra time on it, but worth it imo. It is not an insulated cup tho. It will not keep your drink same temp. I drink iced lattes and don’t mind if the ice melts before I finish it.

I really wanted to like this cup, but the lid is terrible. The opening to drink from is too small, so it's like I'm pouring coffee in my mouth instead of drinking it. The plastic smells awful, even after soaking in white vinegar and running through the dishwasher. I tried using it without the lid, but it easily knocked over and spilled coffee everywhere. I'd recommend skipping this one.

As a frequent coffee/tea drinker, these are by far my favorite travel cup design. The glass helps avoid the metallic taste you get from most traditional travel mugs when transporting hot beverages. Glass also lets the drink cool off a little bit so you avoid burning your tongue, and it’s great for cold drinks as well. I’ve been using these for years and have only had one break on me when I dropped it on concrete. I usually prefer the 16 ounce, but the 12 ounce is great for cappuccinos!
