The case for putting ice in your thermos (when you’re brewing hot coffee)

minimum dose size?

I use the Hario switch to brew my coffee and am trying to reduce my caffeine consumption. Hence I would like to brew smaller cups of coffee. I am currently using 10g of coffee with 160g of water. (1:16 Ratio) I am wondering if there is a minimum amount of coffee...

The case for putting ice in your thermos (when you’re brewing hot coffee)

For a long time now I've had a bit of a vendetta against thermoses. The intention of a thermos is to hold your coffee at a hot temp so that you can drink it slowly throughout the day, but in my experience, the coffee is too hot to drink and turns acrid long before I get to drink it. I've certainly never dumped out thermos coffee because it was too cold, but I have often dumped it because it just tasted bad and harsh. For a long time, I've attributed this bad flavor to some interaction between the stainless steel and the coffee, but recently I've realized that it's not the material in the thermos (it happens no matter what material it is) but it's the high temperature that the coffee is being held at for extended periods.

To solve this, I've been testing adding a few ice cubes into my thermos to chill the coffee down slightly to 140 F or so to make it drinkable immediately and to reduce the cooked flavor that results at holding it at high temps. The result has been everything I've wanted from a thermos, flavorful, fruity coffee for long enough periods that I can drink it slowly over time. I have two rough starting point recipes below, essentially the same ratio. YMMV depending on the coffee, the brew temp, the type of thermos, etc. so play around until you get your desired result.

1) 18 g coffee : 270 g water : 30 g ice

  • Brew the 18 g of coffee as desired, targeting a slightly higher strength than preferred (I've been using a V60 to good results but no reason not to use any other brewer). Slightly prewarm the thermos with the preheat water, then just before the coffee is added into the brewer, add 30 g of ice. In my experience this led to approx. 140 F coffee.

2) 36 g coffee : 500 g water : 50 g ice

  • Brew as above, warming the thermos up then adding the ice just before the coffee. Adjust ratios as needed to hit preferred strength and temperature.

That's it! This isn't a fully fleshed out and rigorously tested idea, just something I've been messing around with and enjoying the results, I hope you have some fun and good results with it. Cheers.
