Grind Size for Breville Barista Touch (2026)

What grind size should you use for Breville Barista Touch?

Use grind level 14 first, then change one step at a time after you watch the flow, time the shot, and taste it. That number is a baseline, not a universal best setting, because beans and grinders do not behave like identical measuring cups.

For a controlled starting shot, keep a double-espresso dose fixed, measure the drink in the cup, and aim near a 1:2 coffee-to-espresso ratio in roughly 25 to 35 seconds. Espresso Aficionados presents that as a general dial-in starting point, not a Breville specification.

What will you need to dial in the Barista Touch grinder?

You need fresh beans, the same basket for every try, and a scale with a timer. The scale matters most because it shows whether a change helped, instead of leaving you to guess from a crema that can look pretty even when the cup tastes sharp.

• Fresh beans: Use one bag while you dial in.
• Scale and timer: Measure dry coffee, espresso out, and shot time.
• Clean portafilter and basket: Keep the same basket and dry it before dosing.
• Consistent tamp: Load and press the grounds level each time.

How do you set a baseline and dial in the Barista Touch?

Set level 14, make one measured shot, and change only the grinder setting until the flow and taste improve. Keeping everything else the same is what makes the next shot a useful comparison rather than another uncontrolled variable.

1. Warm up and choose one coffee

Run the machine until it is ready, use one coffee bag, and purge any stale grounds before dosing. A new bag can need a different setting, especially as it ages, so do not chase yesterday’s number.

2. Lock in dose and output

Use the same double basket, dose, distribution, and tamp. Weigh the espresso as it lands and begin around twice as much liquid espresso as dry coffee, the 1:2 guide from Espresso Aficionados.

3. Pull and read the shot

Start a timer when brewing begins. A shot near 25 to 35 seconds that tastes sweet and rounded is a useful first target; a lemony rush or harsh, dry finish means you still have work to do.

4. Move one step, then repeat

Change the Barista Touch one setting finer for a fast, thin, sour shot. Move one setting coarser for a slow, bitter shot. Clive Coffee’s dial-in guide follows the same symptom-first approach.

5. Write down the winning setting

Note the coffee, setting, dose, output, and time when the cup tastes good. That small note saves you from starting over when you buy the same roast again.

Which mistakes make the Barista Touch grind setting misleading?

The big mistake is changing several things at once, because you cannot tell which change fixed the shot. A printed grinder number is not a universal particle-size measurement, so another owner’s level 6, 8, 14, or 15 is only a clue.

• Changing dose with grind: Breville support notes that finer grounds can change how much coffee fits in the basket. Keep an eye on dose even when grind is your main adjustment.
• Altering grind time first: That alters dose and hides whether the grind was the problem.
• Ignoring retained grounds: Purge a little coffee after a big adjustment so the old setting does not affect the next comparison.
• Using a different tamp each time: A crooked or loose tamp can make a good setting look wrong.

Breville’s Barista Touch support material explains why dose and grind are linked. Treat the screen number as a repeatable reference for your machine, not a number to copy blindly.

What should you do when a Barista Touch shot is sour, bitter, fast, slow, or choked?

Fix the symptom with one grind move first, then check dose, tamp, basket fill, and stale grounds if the shot still misbehaves. Clive Coffee and Espresso Aficionados both frame dial-in this way: control the simple stuff before you reach for a bigger change.

Fast, thin, or sour

Go one step finer. Water is finding gaps too easily, so the shot can gush out pale and taste like sharp citrus without the sweetness underneath.

Slow, bitter, or choked

Go one step coarser. If the machine drips or nearly stops, also check that the basket is not overfilled, the tamp is level, and old fines are not sitting in the grinder chute.
