Why Tamping Matters
Even Extraction
Level tamp creates uniform density for even water flow
Impact: Prevents channeling and uneven extraction
Consistent Results
Same pressure and technique = same results
Impact: Repeatable shots every time
Proper Puck Formation
Compressed puck resists water appropriately
Impact: Correct extraction time and flavor
Tamper Types
Stock Plastic Tamper
Included with machineQuality: Poor
Pros: Free, functional
Cons: Wrong size often, uncomfortable, inconsistent results
Verdict: Replace as soon as possible
Basic Aluminum Tamper
$15-30Quality: Good
Pros: Correct size, comfortable, affordable
Cons: Manual pressure control needed
Verdict: Good budget upgrade
Calibrated/Spring Tamper
$40-80Quality: Very Good
Pros: Consistent 30lb pressure, removes technique variable
Cons: More expensive, some find click annoying
Verdict: Best for consistency seekers
Premium Tamper (Pullman, Normcore)
$80-150+Quality: Excellent
Pros: Perfect fit, beautiful design, lifetime durability
Cons: Expensive, marginal improvement over calibrated
Verdict: For enthusiasts
Stock vs Upgraded
Size Fit
Stock: Often undersized (leaves gaps)
Upgraded: Precise fit to basket diameter
Improvement: Even extraction across puck
Comfort
Stock: Awkward plastic handle
Upgraded: Ergonomic design
Improvement: Better control, less fatigue
Consistency
Stock: Hard to apply even pressure
Upgraded: Easier to tamp evenly (especially calibrated)
Improvement: More repeatable results
Durability
Stock: Plastic wears quickly
Upgraded: Metal lasts years/lifetime
Improvement: Long-term value
How to Tamp Properly
Distribute Grounds First
Technique: Tap side of portafilter, use WDT tool, or shake gently
Why: Even distribution before tamping prevents channeling
Place Tamper Level
Technique: Rest tamper flat on grounds, keep wrist straight
Why: Level start ensures level finish
Apply Firm Pressure
Technique: Press down with ~30 lbs pressure (firm push)
Why: Compresses grounds without overdoing it
Polish (Optional)
Technique: Light twist at bottom of press
Why: Smooths surface, largely aesthetic
Check Level
Technique: Look at puck surface before inserting
Why: Catch uneven tamps before extraction
Common Mistakes
❌ Tamping Too Hard
Problem: Doesn't improve extraction, just tires your wrist
Fix: Firm consistent pressure is enough (~30 lbs)
❌ Uneven Tamp
Problem: Water channels through thinner areas
Fix: Keep wrist straight, practice level technique
❌ Wrong Size Tamper
Problem: Gaps around edge allow channeling
Fix: Measure basket, buy matching diameter
❌ Tamping Without Distribution
Problem: Uneven density before tamping
Fix: Always distribute grounds before tamping
