Clarifying Coffee Techniques

Introduction

• Goal: Create a perfectly clear espresso martini.
• Techniques used: Agar agar, whole milk, charcoal filtering, and combinations.
• Aim: Clear, colorless coffee without special equipment.
• Misconception: Clarified cocktails don't need to be colorless but transparent and without cloudiness.
• Clarification: Retain some original flavors while making coffee clear.

Techniques

1. Agar Agar Clarification

• Purpose: Turn liquid into a gel trapping solids.
• Process:
  • Pull two shots of espresso.
  • Weigh espresso (51 grams).
  • Use 0.02% of the weight in agar agar powder.
  • Boil agar agar in water, mix with espresso, and refrigerate.
  • Gel traps cloudy bits; let it melt through a filter for clear liquid.
• Outcome: Cleaner taste but still dark.

2. Milk Clarification

• Purpose: Use milk to separate colors and flavors.
• First Attempt: Espresso was too concentrated.
• Using Cold Brew:
  • Ingredients: Nitro cold brew, whole milk, vanilla extract, citric acid.
  • Heat milk, add citric acid, mix with cold brew and vanilla extract.
  • Use nut milk bag to filter.
  • Process yielded clearer coffee but still dark.

3. Activated Charcoal Filtration

• Purpose: Absorb impurities and pigments.
• Process:
  • Add activated charcoal to milk clarified cold brew.
  • Let sit for 5 minutes.
  • Filter through coffee filters; unsuccessful due to insufficient fineness.
• Alternative: Use Brita water filter.
  • Multiple passes through Brita to achieve clarity.
  • Resulted in yellow tint but clear coffee.

4. Final Experiment

• Using Starbucks Cold Brew:
  • Repeat milk clarification.
  • Use Brita filter for clarity.
  • Better flavor retention compared to charcoal method.
  • Recommendation: Rinse Brita filter between passes.

Conclusion

• Outcome: Clearest coffee achieved at home.
• Espresso Martini: Cool and tasted great, but primarily a gimmick.
• Reflection: Clarification experiments are fun but challenging.
  • Clarified cocktails can lose original drink essence.
  • Process is arduous and may not be worth the outcome.
• Final Thoughts: Enjoyed the experiment; invites viewer feedback.
