Which thermos keeps chai hot the longest?
Look for stainless steel with double-wall vacuum insulation – that is what keeps heat in. Bigger flasks hold heat longer than small bottles because there is more hot liquid inside. Our flask gift set and 500 ml insulated bottle are listed as keeping drinks hot for up to 12 hours; real results depend on how hot the tea is, how full the flask is and how often you open it.
Simple trick: pour hot water into the thermos for two minutes, empty it, then fill it with tea. A pre-warmed flask keeps chai hot noticeably longer.
Which size do you need?
- 300 ml – one large cup of tea; fits small bags and lunch boxes.
- 500 ml – two cups; the usual size for office and university.
- 1.2 – 1.7 L – the whole family’s chai on a road trip, for guests, or for night duty.
How to clean and look after a thermos
- Wash with warm water and a bottle brush; leave the lid open to dry so it does not smell.
- For tea stains, fill with warm water and a spoon of baking soda, leave for an hour, then rinse.
- Hand wash insulated bottles – dishwashers and freezers can damage the vacuum seal.
- Leave a little space at the top when filling with hot drinks, and close the lid fully before putting it in a bag.
