A weak cappuccino is one made with the usual shot of espresso but more milk, so the coffee tastes diluted rather than reduced. A standard cappuccino puts about 25 ml of espresso under roughly 100 ml of milk; a weak one keeps the shot and pours more milk over it.
If yours came out weak and you didn’t mean it to, that is a fault rather than a style, and why a cappuccino comes out watery goes through the causes. This page is about making a milder one on purpose.
One thing worth being precise about: a weak cappuccino isn’t necessarily lower in total caffeine. A single shot of espresso contains roughly 63mg of caffeine, regardless of how much milk you pour on top of it. If the same shot size is used, as in the recipe below, the caffeine amount stays the same. It’s the concentration and the strength of flavor per sip that drops, not the total caffeine in the cup, unless you deliberately pull a shorter shot.
Some people prefer the weaker style because it’s gentler and less overwhelming than a traditional espresso-forward drink. Others stick with the bolder, more traditional cappuccino for its stronger flavor and more pronounced coffee character.
How Do You Make A Weak Cappuccino?
To make a weak cappuccino, you will need an espresso machine, a frother or steaming wand, and the following ingredients. A standard cappuccino cup holds around 5 to 6 ounces (150 to 180 ml), and a weak cappuccino usually fills the same size cup, it just rebalances what’s inside it toward more milk and foam:
- Espresso: one standard shot, about 25 ml or a little under 1 oz. You are not cutting the coffee, you are adding milk.
- Milk: enough to fill the rest of the cup, which is noticeably more than the 100 ml a standard cappuccino takes.
- Foam: A small dollop of foam on top of the milk.
Here is a step-by-step guide to making a weak cappuccino:
- Grind and tamp your coffee beans as you would for a regular espresso shot.
- Heat up your espresso machine and pull a normal single shot, around 25 ml.
- Pour the shot of espresso into a cappuccino cup.
- Fill a pitcher with cold milk and place the steaming wand just below the surface of the milk.
- Turn on the steaming wand and move it around in the milk until it becomes frothy and the volume has doubled.
- Pour the frothed milk over the espresso in the coffee cup.
- Use a spoon to scoop a small dollop of foam onto the top of the cappuccino.
- Serve immediately and enjoy your weak cappuccino.
Occasionally I do enjoy a weak coffee, I must admit! Say mid-afternoon, not quite decaf time but don’t really want the full on capp experience. Just don’t tell anyone.
