here is my reply to you.
from SB: However, I didn't really feel that much huge difference with iced coffee made using this method, compared with hot brewed pre-ground coffee, let it sit in french press for 5 minutes, and then slowly pour it over coffee filter over ice, mix the resulting coffee drink with milk, sugar, ice, voila, nice iced coffee.
From Ensoluna reply : the biggest difference between cold and hot is that good cold coffee will not have acidity, so it will taste much smoother and rounder.
for hot french press will have the acidity of coffee, of course it will be depends on the coffee, as example coffee from huehuetenango, Guatemala will have way more acidity than Sumatra from Indonesia. However, if you mix with milk, sugar, vodka, cinnamon...etc, IT WOULD NOT MATTER WHICH METHOD YOU USE :+(
From SB : The question that comes to my mind, since buying a cold drip equipment costs quite a lot, I must be really confident that this cold drip style could yield even better coffee than regular cold brew - french press coffee. But could it?
From Ensoluna : it will not cost much at all. As Peter said, below $20 from Amazon. you can get very good equipment and it will last super long time because there is nothing to break. BTW, there is huge difference in flavors between real good cold brew vs hot french press coffee that is cooled with ice. there is no comparison.
