I drink my coffee during my morning commute, usually 45-60 mins long. Nearly every travel mug I have is insulated so well that its still scalding hot an hour after I arrive, so I have been using a plastic travel mug instead. This work, it cools to a drinkable temperature after about 10 minutes, but I can taste the plastic. Something is leeching into my coffee and it gets astringent during the last half. Awful. I need something new. Most mugs advertise they keep it hot for 6 hours! I dont want to wait 6 hours to drink my damn coffee!! /rant

Anyone else have this problem and good suggestions? I'm all ears. Thanks!

I use a 12 Oz ceramic mug with a silicone lid. Ceramic is perfect for coffee. It initially sucks some of the excess heat out of the coffee and then maintains a fairly stable temp after that. It's dishwasher safe, microwave safe and imparts no flavor like plastic and stainless.

This seems like my best bet. I was searching and it looks like a ton of people make them on etsy for this very purpose. I was surprised to find Yeti makes one and hilariously they still added the vacuum insulated steel.

Thanks!

Depending on your local of course, but I've been partial to Nova Ceramics.

Etsy options probably abound as well.

Pour it from high up into your insulated cup? Like pouring it back and forth once will cool it a surprising amount. I’m all for not buying unnecessary shit

[-] Screen_Shatter@lemmy.world 2 points 1 month ago

I'll try that for now. I'm usually frugal too but this is one of the things where I will pay for some convenience.

I pay for convenience all the time, to a degree where I feel like I’m being a wasteful person sometimes. But cooling down a hot beverage feels like something I would hate myself for not figuring out how to do for free.

If you usually make a kind of coffee where you dilute a concentrate (americano, aeropress…) you probably would have already thought of diluting with cooler water. Assuming you don’t want to play around with ratios I think your best bet is using the mugs you have and just making the coffee cooler before you pour it in.

Maybe make it in a chilled receptacle? Like if it’s a pour over or a pod coffee where you make it in a container and pour it into your mug. Glass might break though. Maybe.

Maybe have iced coffee? Or drop a solitary smaller ice cube into the coffee, if you don’t mind the dilution?

Maybe try drinking the hot coffee at your destination as the intentional routine instead?

Why am I now invested in this all of a sudden? I think I would personally drop a small ice cube in or pour a tiny bit of cold water or leave the mug in the fridge overnight if we’re talking like it’s still devil’s piss hot by midday

I hear you about finding just the right answer, but is it an option to use a random stainless insulated mug and then leave the top off, until it's the right temp?

Roads are rough until I hit the highway, its a good way to get coffee splashed around. I have performed the sacrilege of dropping ice cubes in it, and sometimes I will pop the top off when I get to the smoother roads.

Oh boy, you just walked right into the marketing pitch of Temperfect, it has insulation wax on the inside that melts and cools it down to drinkably hot then maintains that temp.

Ok this interesting indeed. Have you tried this? It sounds like scifi

[-] Einskjaldi@lemmy.world 1 points 1 month ago

Yeah it works. It's the same concept as ice. It's just less convenient but it works well in insulated mug.

I have one and love it. The only downsides for me are the cost and the fact that the mug is somewhat heavy even when empty.

For tea, I make it twice as strong as I'd like, then add cold water in my insulated mug. Also less cold water in the winter than in the summer for that bit of flexibility. Not sure how well this transfers to coffee though.

Scalding coffee is bad generally. Experiment with darker roasts or cold brews.

Temperature by Roast and Style

Light roasts: Need hotter water (202°F–205°F / 94°C–96°C) to pull out locked-in flavors.

Dark roasts: Need cooler water (190°F–195°F / 88°C–90°C) to stop bitter tastes.

Cold brew: Uses cold or room-temperature water (35°F–70°F / 2°C–21°C) over 12 to 24 hours

[-] Screen_Shatter@lemmy.world 1 points 1 month ago

My brew temps are in that range but I think drinking anything at 200 degrees is hazardous to your health!

[-] Malyca@lemmy.zip 2 points 1 month ago

I bought one of those mugs with a battery. You can set the temp to whatever you want and it'll keep it that temperature.

[-] Coelacanth@feddit.nu 3 points 1 month ago

They are great, worth the price in my opinion even though they can seem like luxury objects.

[-] jimerson@lemmy.world 2 points 1 month ago

I make my coffee slightly stronger and plop a couple ice cubes in. Perfect temp after 5 minutes and stays at perfect temp for a long time.
