Are they safe for coffee?

I gave these as a wedding present to a couple I hang out with quite often, and they said they really liked them and used them often. They drink a lot of coffee. Therefore, I am assuming they are safe for coffee!

My wife will warm coffee up in them, so for 25 seconds or so, they appear microwave safe. That minor amount of radiation also has not affected the image quality on the cups. For what it's worth.

No. They are plastic on the bottom. These keep the coffee warm without heat. Thermal carafe, like a thermos.

I'm quite sure they are... don't think your dishwasher water will be hotter than the coffee.. ;)Maybe I should ask who the dishwasher is...lol

I have never tried this, but I do wash them in hot water and they are fine. I would say it would be safe as long as you run them under hot water first and be sure to get the inside and outside equally hot. I love them for cold drinks, because they don't sweat, and they keep the drink cold for a long time. I guess they must keep hot drinks warm for quite some time, too.

Shouldn't be a problem but to be safe check the manufacturer's instructions. They are made to handle boiling hot liquids.

Yes they are. We use them to keep some of the fine particles out of the coffee. It seems to make a smoother stronger cup. 300 filters seem to last forever. Buy them with the coffee maker because they are hard to get by themselves unless you buy a bunch. Good luck! We love our one cup maker.

Yes and they work very well. They definitely last for the 60 cups. Coffee is delicious.

I use them in my drinks. I have had a few leak but they are safe. I use them every day.

No, they are quite fragile. But, they are amazing for drinking a nice latte.

Yes. They are perfect for keurig machines when you want to use your own coffee rather than buy the individual coffee cups. We use them all the time and will be reordering soon.

They are not entirely airtight (I don't know how it would do with keeping coffee completely fresh ....depends on how quickly you use your coffee...perhaps if you left it in the bag and then placed in container). I use mine for flour, sugar and tea bags, as well as dry dog food. All have done very well after many months of use.

Yes. I use these mugs for heating up water in the microwave for instant coffee.

I'm not sure if they are microwave safe or not but didn't see it anywhere so would go with no. They are great cups though and the three sizes makes them that much more convenient.

I have not put them in the microwave so I really don't know if they are microwave safe. I love my mugs though.

Nope, they are for espresso, so it will be handle-able. If you fill it with hot coffee to the top, maybe it will be an issue. But it's ideal for 2oz or lungo 4oz shots in my opinion. I do not hesitate to buy again :)Tehre are others with insulation, but i think that is more to keep the coffee warm as opposed to protection from burn

Absolutely. I use them for brewing All-Grain craft beer, and I have to have a temp of 165 F-175 F for 2 hours to convert the barley starches into sugars, so your coffee will be nice and hot for a good 8 to 10 hours, at the least. I hope this helped you.by nirvanabrewery8/2/2014
