In cold brew, ratio is not only about intensity. It decides whether you are making a concentrate to dilute later or a ready-to-serve beverage, and with it change extraction, body and perceived sweetness.
The ratio is the variable that determines whether your espresso is concentrated and short or long and mild. Understanding the relationship between ground coffee and extracted liquid is the key to precise extraction control.
Water temperature is the most overlooked French Press variable, but its effect on acidity, bitterness, and body is measurable and consistent. Working range: 80–96 °C, with very different results at each extreme.
