Turns out that Heet in the Red Bottle is usable (but not really), if necessary; and you don’t mind a really sooty pot, and alcohol floating on the top of your liter of water,
And you don’t mind cleaning it all up, and then opening up the house (in winter) to air things out!
I’m pretending the tea tastes alright!
The water boiled in 9 minutes, spent 30 minutes cleaning up; and still airing out the house (45 minutes later)
Looks like the yellow bottle next time (outside) it should be warm enough then!!!
