Steep Time Chart

Steep Duration Strength Flavor Profile Caffeine Level Best For
8-12 hours Light Tea-like, subtle Moderate Ready-to-drink (no dilution)
12-16 hours Medium Balanced, smooth High Versatile concentrate
16-20 hours Strong Rich, full-bodied Very High Diluted drinks
20-24 hours Very Strong Intense, concentrated Maximum Heavy dilution (1:2 or more)

Step-by-Step Beginner Guide

Step 1: Measure Ingredients (2 minutes)

  1. Weigh coffee: Measure 100g coarse ground coffee (approximately 1 cup)
  2. Measure water: Prepare 400ml cold filtered water (approximately 1.5 cups)
  3. Verify ratio: Confirm 1:4 coffee-to-water ratio for concentrate

Step 2: Combine Coffee and Water (2 minutes)

  1. Add coffee to jar: Place ground coffee in clean glass jar
  2. Pour water slowly: Add cold water gradually while stirring
  3. Saturate grounds: Ensure all coffee is wet—no dry pockets
  4. Stir thoroughly: Mix for 30 seconds to eliminate clumps

Step 3: Steep (12-24 hours)

  1. Cover container: Place lid or plastic wrap on jar
  2. Room temperature or refrigerator: Both work; room temp extracts faster
  3. Set timer: Mark start time, plan for 16-hour steep
  4. Occasional stir (optional): Agitate once halfway through if convenient

Step 4: Filter (5 minutes)

  1. Prepare strainer: Line mesh strainer with cheesecloth or use nut milk bag
  2. Position over container: Place over clean jar or pitcher
  3. Pour slowly: Transfer cold brew mixture through filter
  4. Allow drainage: Let liquid pass through without squeezing initially
  5. Press grounds gently: Lightly squeeze bag to extract remaining liquid
  6. Discard grounds: Compost spent coffee grounds

Step 5: Store and Serve (2 minutes)

  1. Transfer concentrate: Pour filtered cold brew into clean storage container
  2. Refrigerate: Store in refrigerator for up to 2-3 weeks
  3. Dilute to taste: Mix concentrate 1:1 with water or milk for serving
  4. Serve over ice: Pour over fresh ice cubes

Grind Size Guide

Grind Size Visual Reference Steep Result Filtration
Too Fine Sand-like, powdery Bitter, over-extracted Difficult, clogs filters
Correct (Coarse) Kosher salt, rough Smooth, balanced Easy, minimal sediment
Too Coarse Large chunks, uneven Weak, under-extracted Very easy, fast

Recipe Ratios for Different Batch Sizes

Batch Size Coffee Water Yield (Concentrate) Servings
Small 50g 200ml ~180ml 2-3 drinks
Medium 100g 400ml ~350ml 4-6 drinks
Large 200g 800ml ~700ml 8-12 drinks
Ready-to-Drink* 60g 500ml ~450ml 2 drinks (no dilution)

*Ready-to-drink ratio uses more water for immediate consumption without dilution

Troubleshooting Common Issues

Problem Likely Cause Beginner Fix
Too bitter Steeped too long or grind too fine Reduce steep time to 12-14 hours; use coarser grind
Too weak Steeped too short or too much water Extend steep to 18-20 hours; check 1:4 ratio
Muddy sediment Grind too fine or inadequate filtering Use coarser grind; double-filter through cheesecloth
Stale/off flavors Old coffee beans or storage issues Use coffee within 4 weeks of roasting; fresh water
Oily film on top Natural coffee oils from dark roast Normal occurrence; skim off or stir in
Cloudy appearance Fine particles suspended Let settle, pour carefully; filter again if desired
