Dialing in Espresso shot taste

Coffee taste can vary from cup to cup for many reasons. If you are not happy with your Koffee Kult coffee you can fix the taste by adjusting the grind and/or the water temperature. A properly ground and weighed shot will produce a perfect shot.

These adjustments will be subjective, and there may be more than one optimum set up for the blend, especially if it is complex in taste.

What Is "Dialing In" Espresso?

Dialing in is the process of making small adjustments to your espresso variables until you achieve the perfect shot. It's part science, part art, and requires patience and tasting!

The Main Variables You'll Adjust:

⚙️ Grind size - Fine to coarse
⚖️ Dose - Amount of coffee (grams)
⏱️ Extraction time - How long water flows through
?️ Temperature - Brew water temperature
? Pressure - Pump pressure (usually fixed at 9 bars)
? Yield - Amount of espresso out (volume/weight)

Understanding Espresso Extraction

The Goal: Balanced Extraction

Perfect espresso tastes:

• ✅ Sweet and balanced
• ✅ Rich crema on top
• ✅ Complex but harmonious
• ✅ Smooth mouthfeel
• ✅ Pleasant aftertaste

Extraction zones:

• Under-extracted (<18%) = Sour, weak, thin
• Optimal (18-22%) = Balanced, sweet, complex
• Over-extracted (>22%) = Bitter, harsh, astringent

The Standard Espresso Recipe

Starting Point (Adjust from here):

☕ Dose: 18-20g of coffee
? Yield: 36-40g of espresso (1:2 ratio)
⏱️ Time: 25-30 seconds
?️ Temperature: 195-205°F (90-96°C)
? Pressure: 9 bars

This is your baseline - adjust based on taste!

Common Espresso Problems & Fixes

Problem: Not Sweet Enough (Sour Taste) ?

What's happening: Under-extraction - not enough flavor compounds extracted

Symptoms:

• Sour, acidic taste
• Thin body
• Weak crema
• Pulls too fast (under 20 seconds)
• Light colored crema

Solutions:

Do more ristretto shots, grinding finer and stopping at the same color. This will take the shot out of the optimum crema range, so it has to be a good crema blend. You can also center cut the shots; however, this will reduce the distinctive flavors and can lead to blandness. On the other hand, somewhat bland center cut shots are good way to serve newcomers to straight espresso, or those who prefer more subtle flavors.

Specific fixes:

1. ⚙️ Grind finer- Most effective fix
   • Adjust one notch finer at a time
   • Increases extraction
   • Slows down flow
2. ?️ Raise temperature- 2-3 degrees higher
   • Better extraction of flavor compounds
   • Try 200-203°F range
3. ⏱️ Extend extraction time
   • Aim for 28-32 seconds
   • More contact time = more extraction
4. ⚖️ Use more coffee(increase dose)
   • Try 19-20g instead of 18g
   • More coffee = more flavor extraction
5. ? Pull longer shot(increase yield)
   • Try 1:2.5 ratio instead of 1:2
   • More water extracts more compounds

Problem: Over-Intense Flavors (Bitter Taste) ?

What's happening: Over-extraction - too many compounds extracted, including bitter ones

Symptoms:

• Bitter, harsh taste
• Dry, astringent mouthfeel
• Pulls too slow (over 35 seconds)
• Very dark crema or no crema
• Channeling or spurting

Solutions:

Lower the pump pressure. If this is because there's not enough sweetness to balance the bitters and sours, use the previous fix. Also consider going more lungo with the same stop color.

Specific fixes:

1. ⚙️ Grind coarser- Most effective
   • Adjust one notch coarser
   • Decreases extraction
   • Speeds up flow
2. ?️ Lower temperature- 2-3 degrees cooler
   • Less extraction of bitter compounds
   • Try 195-198°F range
3. ⏱️ Shorten extraction time
   • Aim for 22-26 seconds
   • Less contact time = less bitterness
4. ⚖️ Use less coffee(decrease dose)
   • Try 17-18g instead of 19g
   • Less coffee = less over-extraction
5. ? Pull shorter shot(decrease yield)
   • Try 1:1.8 ratio instead of 1:2
   • Ristretto-style for sweetness

Problem: Pallid Flavors (Weak, Bland) ?

What's happening: Under-extraction OR improper distribution/tamping

Symptoms:

• Weak, watery taste
• Pale crema or no crema
• Pulls too fast
• Might look "blonde" quickly
• Thin body

Solutions:

Raise the pressure. Also consider going more ristretto with the same stop color.

Specific fixes:

1. ⚙️ Grind much finer
   • Current grind way too coarse
   • Need more resistance
2. ⚖️ Increase dose significantly
   • Use 19-20g
   • More coffee = more flavor
3. ? Check distribution
   • Use WDT (Weiss Distribution Technique)
   • Break up clumps before tamping
   • Ensure even puck
4. ? Tamp properly
   • Use consistent, firm pressure
   • Level tamp
   • About 30 lbs of pressure
5. ? Check machine
   • Low pressure? (should be 9 bars)
   • Clogged shower screen?
   • Old gaskets leaking?

Problem: Overly Sour Taste ?

What's happening: Severe under-extraction

Symptoms:

• Intensely sour, acidic
• Mouth-puckering
• Very fast extraction (under 20 sec)
• Pale, thin crema
• Watery consistency

Solutions:

Raise the temperature. Short term, try stopping lighter and grinding finer to keep the volume the same. If it's really bad, start-dump.

Specific fixes:

1. ⚙️ Grind MUCH finer - Several notches
2. ?️ Increase temp to 200-205°F
3. ⏱️ Slow down extraction to 28-32 seconds
4. ⚖️ Increase dose by 1-2 grams
5. ? Check for channeling - uneven extraction

"Start-dump" technique:

• Start extraction as normal
• If pulling too fast and sour, stop immediately
• Dump the shot and adjust

Problem: Overly Bitter Taste ?

What's happening: Severe over-extraction

Symptoms:

• Intensely bitter, harsh
• Astringent, dry mouthfeel
• Very slow extraction (over 40 sec)
• Very dark or no crema
• Heavy, syrupy consistency

Solutions:

Lower the temperature. Short term, try stopping darker and grinding coarser to keep the volume the same.

Specific fixes:

1. ⚙️ Grind MUCH coarser - Several notches
2. ?️ Decrease temp to 195-198°F
3. ⏱️ Speed up extraction to 22-25 seconds
4. ⚖️ Decrease dose by 1-2 grams
5. ? Clean machine - old coffee oils taste bitter

The Dialing In Process: Step-by-Step

Step 1: Start with the Standard Recipe

Baseline:

• 18g dose
• 36g yield (1:2 ratio)
• 25-30 second extraction
• 200°F temperature

Pull a shot and taste it critically.

Step 2: Identify the Problem

Ask yourself:

• Is it sour or bitter?
• Is it weak or too strong?
• How's the mouthfeel?
• What about the crema?
• How was the extraction time?

Step 3: Make ONE Adjustment

Only change one variable at a time!

Priority order:

1. Grind size (most impactful)
2. Dose (second most important)
3. Temperature (fine-tuning)
4. Yield (advanced)

Step 4: Test and Taste

Pull another shot with your adjustment.

Compare to previous shot:

• Better or worse?
• Getting closer?
• Need more adjustment?

Step 5: Repeat Until Perfect

Keep adjusting and tasting until you achieve:

• ✅ Balanced sweet and bitter
• ✅ Rich, thick crema
• ✅ Smooth mouthfeel
• ✅ 25-30 second extraction
• ✅ Pleasant complexity

This may take 3-10 shots to dial in!

Visual Guide: Espresso Extraction

What Good Crema Looks Like:

✅ Perfect crema:

• Reddish-brown color
• Thick and persistent
• Smooth, creamy texture
• No large bubbles
• Covers entire surface

❌ Bad crema:

• Very pale (under-extracted)
• Very dark or none (over-extracted)
• Large bubbles (channeling)
• Thin and disappears quickly
• Spotty or uneven

Espresso Flow Stages:

Stage 1: Pre-infusion (0-5 seconds)

• No visible flow yet
• Building pressure
• Saturating puck

Stage 2: Honey Phase (5-10 seconds)

• Dark, syrupy drips
• Looks like honey
• Rich, concentrated

Stage 3: Blonde Phase (25-30 seconds)

• Lighter colored flow
• Getting watery
• Time to stop!

⚠️ If blonde phase starts before 20 seconds = grind finer!

Advanced Dialing In Techniques

Temperature Surfing (for non-PID machines)

What it is: Timing your shot pull for optimal temperature

How to do it:

1. Let machine heat fully
2. Run blank shot to purge
3. Wait 20-30 seconds
4. Pull shot (temperature now stable)

Pressure Profiling (for advanced machines)

Varying pressure during extraction:

Pre-infusion:

• Start at 2-4 bars for 5-10 seconds
• Gently saturates puck
• Prevents channeling

Main extraction:

• Ramp to 9 bars
• Standard extraction pressure

Declining profile:

• Drop to 6 bars at end
• Extracts more sweetness
• Less bitterness

Basket Size Matters

Standard baskets:

• 14-16g (single)
• 18-20g (double)
• 20-22g (triple)

Match your dose to basket size for even extraction!

Troubleshooting Extraction Issues

Channeling

What it is: Water finds path of least resistance, creates uneven extraction

Signs:

• Spurting or spraying
• Fast extraction with sour taste
• Uneven crema
• Donut pattern in puck

Fixes:

• ✅ Better distribution (WDT tool)
• ✅ Level tamp
• ✅ Fresh coffee (not too old)
• ✅ Appropriate grind (not too fine)
• ✅ Clean basket

Inconsistent Shots

Causes:

• Temperature fluctuations
• Inconsistent dosing
• Uneven distribution
• Varying tamp pressure
• Old/stale coffee

Fixes:

• ✅ Use scale for consistent dosing
• ✅ WDT for distribution
• ✅ Calibrated tamper
• ✅ PID for temp control
• ✅ Fresh coffee only!
