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’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
