What is a “Cup” of Coffee?

What is a “Cup” of Coffee?

The term “cup” can have different meanings when it comes to coffee. Here are some key definitions:

United States:

  • 1 cup = 8 fluid ounces (237 ml)


  • 1 cup = 5 fluid ounces (148 ml)


  • 1 cup = 6 fluid ounces (180 ml)

The variance in cup measurements means precise ratios are critical for consistent results globally. When sharing recipes, be sure to specify ounces or grams to eliminate confusion.

Why Coffee Measurements Matter?

Precision is necessary for proper coffee extraction and flavor. Minor variations in the coffee-to-water ratio can significantly impact the taste of the final brew.

Here are some key reasons why measurements matter:

  • Extraction: The solubles extracted from the coffee grounds determine flavor and body. More precision leads to better control over extraction.
  • Strength: The coffee-to-water ratio directly correlates to beverage strength and caffeine levels.
  • Consistency: Following specific ratios helps achieve consistent results with each brew.
  • Optimization: Precision empowers fine-tuning to find your perfect coffee profile.

How Many Tablespoons Of Coffee Per Cup?

To determine how many tablespoons of coffee to use per cup, the general guideline is to use approximately 1 ½ to 2 tablespoons of coffee grounds for a standard 8-ounce cup of coffee. This equates to about 10.6 grams of coffee per tablespoon. However, the ideal coffee-to-water ratio can vary based on personal taste preferences and the desired strength of the brew. For a stronger cup of coffee, you can increase the amount of coffee used, while for a milder taste, you can decrease the coffee-to-water ratio

Standard Coffee-to-Water Ratio

The specialty coffee industry has adopted a standard recipe for brewing coffee:

1 gram of medium grind coffee for every 18 grams of water

This 1:18 ratio is widely recommended as a starting point by professional baristas and coffee organizations like the Specialty Coffee Association (SCA).

There are a few reasons why the 1:18 ratio became standard:

  • It was scientifically determined to extract an optimal balance of coffee solubles.
  • It produces a brew strength expected by most specialty coffee drinkers.
  • It allows flexibility for adjusting higher or lower based on preferences.

The 1:18 ratio results in a brew strength of about 1.25% dissolved coffee solids when prepared properly. This percentage aligns with specialty coffee standards.

Adjusting the Ratio for Personal Taste

The 1:18 ratio provides a balanced coffee extraction but adjustments can be made based on personal taste:

  • Stronger coffee: Use more coffee grounds per water volume (e.g. 1:15 ratio)
  • Weaker coffee: Use fewer coffee grounds per water volume (e.g. 1:21 ratio)
  • Bolder body: Use slightly more coffee for bolder mouthfeel
  • Brighter flavor: Use slightly less coffee to highlight acidic notes

When adjusting the ratio, change only one variable at a time to understand how it impacts taste. For example, first adjust only the amount of coffee before changing the water amount or grind size.

Make adjustments in small increments of 1 to 2 grams. Continue tasting and tweaking until you find your “just right” ratio for any brewing method.

Measuring Coffee Without a Scale

Many home brewers rely on volume measurements like tablespoons and cups rather than weighing with grams. Here are some tips for success:

  • Grind size matters – Adjust volume up or down to accommodate fine or coarse grinds
  • Level, not heaped – Spoon coffee evenly without compacting grounds
  • Medium grind – Standard tablespoons and scoops are designed for medium grind coffee

Refer to this general guide to translate standard coffee ratios:

Ratio Tablespoons (Medium Grind)
1:18 1 Tbsp per 6 oz water
1:16 1 Tbsp per 5 oz water
1:14 1 Tbsp per 4 oz water

Detailed Coffee-to-Water Ratios by Method

While 1:16-1:18 is a typical range, the ideal ratio can vary based on brewing method.

Drip Coffee Ratios

  • Auto-drip machine: 1:16 ratio
  • Pour over: 1:15 to 1:17 ratio
  • Batch brewers: 1:14 to 1:16 ratio

Filters in drip methods retain some water so a slightly higher coffee-to-water ratio helps achieve proper extraction. Aim for a total dissolved solids percentage of 1.15% – 1.35%.

French Press Ratios

  • Single serving: 1:12 to 1:14 ratio
  • Multiple cups: 1:15 to 1:17 ratio

Since French press lacks a paper filter, a lower ratio prevents over-extraction. 1.25% – 1.35% total dissolved solids is target.

Espresso Ratios

  • Single shot: 1:1.5 to 1:2 ratio
  • Double shot: 1:2 to 1:3 ratio

The concentrated nature of espresso requires a much higher coffee-to-water ratio. Always dose coffee first then add water by weight.

Cold Brew Ratios

  • Cold drip: 1:4 to 1:6 ratio
  • Immersion: 1:8 to 1:10 ratio

Extended cold water contact time requires a lower ratio to prevent over-extraction. Total solubles should be 1.2% – 1.4%.

Achieving the Perfect Brew

Simply following the proper coffee-to-water ratio does not guarantee quality results. Here are some other vital factors:

  • Freshly roasted beans – Stale coffee won’t taste optimal regardless of brewing ratios. Only use coffee roasted within the past 4 weeks.
  • Proper grinding – A consistent grind size and using a burr grinder helps extract the best flavor.
  • Pure water – Good tasting water brings out the notes in coffee rather than masking them.
  • Water temperature – Water too hot can scorch coffee leading to bitterness. Optimal brewing temperature is around 200°F.
  • Brew time – Time the brew cycle based on method for complete flavor extraction. For example:
    • Drip machines: 4-7 minutes
    • Pour over: 2-4 minutes
    • French press: 4 minutes
    • Cold brew: 12-24 hours

Getting all these variables right is crucial to make a balanced, flavorful coffee with the proper ratio alone.

Tweaking Taste with Ratio Adjustments

As you dial in your perfect brew, here are some common flavors to tweak with ratio adjustments:

Bitter and Overly Strong

  • Use less coffee grounds to decrease strength
  • Try a coarser grind size to speed up brew time
  • Lower water temperature slightly

Underdeveloped, Sour or Weak

  • Increase amount of coffee to boost strength
  • Use a finer grind to extend brew time
  • Bump up water temperature

Unbalanced or Muddy

  • Adjust ratio up or down in 1-gram increments
  • Play with grind size from fine to coarse
  • Try water with less mineral content

Take notes each time you change any variable to determine the impact on taste. Soon your taste buds will lead you to the ideal ratio.

Proper Equipment Maintenance

Achieving consistent coffee-to-water ratios depends on properly maintained equipment. Follow these tips:

For Coffee Grinders:

  • Clean inside with grinder brush weekly
  • Use specialty grinder cleaning tablets monthly
  • Calibrate burrs routinely for grind consistency

For Brewing Equipment:

  • Descale machine regularly based on water hardness
  • Clean carafe, portafilter and reservoirs with cafiza or vinegar
  • Replace water filters per manufacturer instructions

Well-maintained equipment improves precision and delivery of hot water for better tasting coffee.

Sustainable Coffee Ratios

Making coffee is more eco-friendly when you:

  • Choose organic and shade-grown coffee beans
  • Select fair trade certified sources
  • Buy from small specialty roasters with sustainable practices
  • Reduce waste by using reusable k-cups and filters
  • Compost used coffee grounds

Brewing coffee sustainably also means making the most of your grounds. Follow recipes and ratios carefully to completely extract flavors without waste.

Comparing Brewing Methods

Each brew method has pros and cons based on individual factors such as:

Method Pros Cons
Pour over Enhanced flavor clarity, portable Time intensive, needs gooseneck kettle
French press Full-bodied, easy to use Sediment in coffee, not ideal for lighter roasts
Drip machine Fast, convenient, consistent Plastic waste from filters, less control
Cold brew Smooth, less acidic Requires 12+ hour steep time
Espresso Layered flavors, creamy foam Expensive equipment required, technical process

Consider your own needs, preferences and lifestyle to determine the best brewing method before settling on a ratio.
