Mugen: 1:18 usually, V60: 1:16ish. (Light and medium roasts)

Ratio will depend on preference, equipment, and what coffee you’re brewing, as well as the recipe. In my case I use a bit longer ratio on the Mugen compared to the V60 because it has less bypass (less water gets around the coffee by going through the filter too soon). Generally speaking folks use shorter ratios for darker roasts and longer ratios for lighter roasts.

It gets a little more complicated with iced coffee, because what you’re doing with iced coffee is actually brewing a very short ratio and then diluting it, which gives you a concentration that is similar to what you would normally get, but with lower extraction. (Not necessarily a bad thing!)
