Cold brew vs iced americano: what's the difference?
Cold brew is coffee steeped in cold water for 12 to 24 hours, never heated; it is smooth, sweet and low in acidity. An iced americano is hot espresso poured over ice and water: brighter, sharper and ready in a minute.
The differences
Brewing: hours in cold water against seconds under hot pressure.
Taste: cold brew is mellow and chocolatey; an iced americano is crisp and more acidic.
Caffeine: cold brew is usually stronger per glass, as it is brewed as a concentrate.
Coarse grounds steeped in cold water for a good long while, then poured straight over ice. No heat at all, so it comes out sweeter and less sharp than a hot shot poured cold.
