Is there a difference in caffeine content if I use cold water/liquid for my instant coffee rather than hot water? I actually want to mix my instant coffee grains with cold soy milk and avoid the hassle of boiling water.

From what I've heard, cold brewing coffee results in higher caffeine levels.

Instant coffee though, is coffee that's already been brewed and the water removed.

I would assume that if you reconstitute instant coffee by adding it to a cold liquid, water or soy milk for example, you are not altering the caffeine content.

If you boil instant coffee down, you lose a lot more water than caffeine, leaving it a more concentrated caffeine laden beverage by default.

If by "hassle" you mean time consuming, try a one cup brewer. It's easier, quicker and safer than stove top. You can add your instant coffee to the hot water.

As for me, I've moved on from instant coffees........... and I'm absolutely lovin' it. :D
