Dialing in espresso is the process of adjusting your grind, dose, and yield to get the best-tasting shot possible.
It sounds technical — but once you understand what to change and why, it becomes fun (and very satisfying).

This guide explains dialing in using simple household setups and entry-level gear, perfect for beginners.

🎯 What “Dialing In” Really Means

Dialing in is adjusting your brewing variables so that your espresso tastes balanced — not too sour, not too bitter.

The three main variables are:

1. Grind size – how fine or coarse the coffee is

2. Dose – how much coffee you put into the basket

3. Yield – how much espresso comes out (in grams)

4. Time – how long the shot takes (usually 25–30 sec)

Your job is to adjust these until the taste lands in the sweet spot.

⚙️ Step 1: Set a Starting Recipe (Simple & Reliable)

A great beginner recipe is:
18g coffee → 36g espresso → 25–30 seconds

This gives a classic espresso ratio (1:2), balanced for most beans.

If your basket takes 16g or 20g, simply follow the same 1:2 ratio.

⚙️ Step 2: Set Your Grinder Close to Espresso Fine

Start with a fine grind — slightly finer than table salt.
Every grinder is different, so don’t worry about numbers.
Just start fine, because:

👉 Too coarse = sour
👉 Too fine = bitter

We'll adjust this shortly.

⚙️ Step 3: Pull a Test Shot & Observe

Pull a shot using your starting recipe.
Write down:

• Dose (ex: 18g)

• Yield (ex: 36g)

• Time (ex: 17 sec or 40 sec)

• Taste

Now let’s adjust based on what you see and taste.

🔧 Step 4: Fix Common Problems (Beginner Cheat Sheet)

❗ If your espresso tastes SOUR

Symptoms: thin, sharp, lemony, fast-flowing

• Make grind FINER (your coffee extracted too fast)

• Aim for a longer extraction time (25–30 sec)

❗ If your espresso tastes BITTER

Symptoms: harsh, burnt, dry mouthfeel, very slow

• Make grind COARSER (your extraction was too slow)

• Aim for smoother, shorter shot

❗ If your espresso tastes WEAK or WATERY

• Increase your dose by 1g

• Or reduce yield slightly (ex: 18g → 32g)

❗ If your espresso tastes TOO STRONG / OVERPOWERING

• Reduce dose by 1g

• Or increase yield slightly (ex: 18g → 40g)

🧪 Step 5: Taste, Adjust, Repeat

Dialing in is not guesswork — it’s controlled adjustments.

Change only one variable at a time:
✔ grind size
or
✔ dose
or
✔ yield

Never change two things at once — you’ll never know which one fixed the problem.

Keep repeating until your shot tastes:

• Balanced

• Sweet

• Smooth

• Pleasant acidity

• No bitterness

📏 Simple Home Dial-In Routine (No Fancy Tools Needed)

Here’s a practical, fast process for everyday home brewers:

1. Grind fine

2. Dose consistently (use a scale if possible)

3. Pull a shot

4. If sour → grind finer

5. If bitter → grind coarser

6. Keep the same recipe all week until beans age

7. Make minor tweaks (beans change slightly after day 7–10)

With just grind adjustments, most beginners get excellent results in under 10 minutes.
