an iced americano is espresso, water, and ice. the espresso is supposed to be diluted. the problem is when you add a lot of warm water, a small amount of ice, and then wonder why it tastes thin five minutes later. i start with cold water and a clear idea of how much i'm adding.
for one drink, pull a double espresso. use about three parts cold water to one part finished espresso as a starting point. if your double shot is about 36 grams, that means roughly 108 grams of added water. you can use a measuring cup instead of weighing the finished shot. fill a sturdy glass with ice, add the cold water, and pour the espresso in. stir once and taste. this is a starting ratio, not a rule that every coffee needs.
if you already know you like a stronger drink, start nearer two parts water to one part espresso. you can always add more water. taking it back out is not possible. the ice will also melt as you drink, so don't make it weak before the first sip. using cold water means the hot espresso doesn't have to chill a glass full of room-temperature water on its way in.
make the espresso first and check it before building the drink. if the shot tastes sharply sour or very harsh on its own, adding less water won't fix that. adjust your espresso recipe next time rather than treating the americano as the problem. if the shot tastes good and the finished drink tastes bland, then change the dilution. keep those two decisions separate.
some people pour the espresso over the iced water to keep a little of the crema visible at first. others add water to the espresso and then pour it over ice. both methods work. the order matters less than the strength of the shot, the amount of water, and starting cold. if you add milk or syrup, that's your choice, but taste the black version first so you know what you're changing.
without an espresso machine, you can make a cold black coffee with concentrated moka-pot coffee and water. i wouldn't call it an iced americano in a recipe, because moka-pot coffee isn't espresso. it can still make a good drink. start with a smaller pour of water and adjust by taste.
my simple version is a double shot, cold water at about three times the shot volume, and enough ice to keep it cold. after one glass you'll know whether you want more espresso flavor or a longer drink. write down the ratio you liked so you can make it again.
Couplet has coffee if you want to try it at home.
