I'm going backpacking in a few weekends, and in order to save on pack weight I've been dehydrating a lot of my meals. As I think about breakfast, I'm settling on carrying only powdered milk and instant coffee for my breakfast cup of joe. I was wondering if anyone has done this and what a good instant coffee to hot water to powdered milk ratio would be. What would the steps for making it look like? Would I add the powdered milk first or the coffee first, or both at the same time? Thanks!

  • You will find instructions on the back of any jar of coffee powder and the same goes for dried milk, however you might find better answers in either coffee or the great outdoors SE sites.

As a disclaimer, I've never done this, but here's the way I would do it if I were you:

First, determine how you like your coffee when its a regular cup of joe. Once you know how much milk you use to however much coffee, determine how much powdered milk reconstitutes to the equivalent amount of regular milk. Then determine how much instant coffee in a glass of hot water makes a comparably sized cup of regular black coffee. When you've done that, you should have measurements for how much instant coffee and how much powdered milk you need for one cup of coffee. (Be sure to make a test cup!)

Then for ease of use on the trail I would scale up the amounts based on how long of a trip and how many cups of coffee you think you'll want and combine the coffee and milk powders. Thoroughly mixed, they can be stored in a single container, and since you know how much instant coffee and how much powdered milk to use separately in a given amount of hot water, you can add those amounts to know how much of the mix to put in your cup on the trail.

I would do powder mix first, then hot water, and stir to combine/dissolve completely.

  • Thanks for the suggestion! I will give this a try this weekend :) Commented Apr 7, 2017 at 14:13
