thermos jugs

by m147 » May 23rd, '11, 14:44

anybody can recommend some brands or what not of good heat-retaining thermos jugs to keep the water warm for multiple infusions?
thank.

i've used the same Nissan Thermos for about 2 decades and i am still happy with it.
any thermos with double wall vacuum insulation is my suggestion.

I saw the title and started to plan my reply but then realized that I use my thermos only for the results of multiple infusions, but never for holding the water before infusions. My Stanley steel vacuum bottles do keep tea brewed at about 205 degrees hot enough to burn my tongue hours later, but I've never checked how fast they actually lose heat re: brewing.

this depends on the type of tea the op is brewing. even opening the screw top slightly to pour out the water will cause the temperature to drop, but for lower temp brewing teas this has never been a problem. with higher temp brewing teas i find after several pours i really should add more near-boiling water.

here's the one i'm looking to get. it's double wall vacuum and you don't have to unscrew the top, just press the button down to pour out the liquid.

here is the north american version

i have not used this thermos but the company and design are good quality. i prefer no parts rather than this pumping system, but maybe this model retains heat better.
even so, it is hard to maintain the heat necessary for a 4th or 5th pour, i think, for oolong teas.

The problem is that the fewer liquid inside the thermos, the cooler the liquid will become. If the thermos is nearly full, it will retain heat for a VERY long time (provided it's a high quality thermos).

So if you're gonna be using a lot of hot water and if it should not be below 75° C or so, get a thermos with a bigger capacity than the amount of water (tea) you consume and fill it to the top regardless. I assume that this would help.
You'd end up with quite a bit of leftover water this way but you can use that for cleaning your teaware afterwards.

so far i've been drinking sencha using this pot for my tea. it seems to do the trick. maybe eventually i'll get myself a water boiler.
