Summary

In this video, John Christopher discusses the common issue of bitterness in coffee, specifically when brewing at home or in shops. He covers the three roasting profiles—light, medium, and dark—and explains how each affects the flavor, with a focus on achieving a balanced, non-bitter taste. He also dives into key brewing variables such as grind size, water temperature, and brew time, offering practical tips to avoid over-extraction. The video provides valuable insights for coffee lovers aiming for a clean, sweet cup of coffee, with guidance on avoiding bitterness in every brew.

Takeaways

• 😀 Light roast profiles provide higher acidity and fruity, aromatic flavors due to undercooked sugars.
• 😀 Medium roast profiles strike a balance between acidity and sweetness, offering a sweeter taste with lower acidity.
• 😀 Dark roast profiles are typically more bitter, favored by those who enjoy strong coffee flavors, often requiring added sugar.
• 😀 To avoid bitterness, choose a light-medium roast and brew at a temperature between 88-90°C for optimal flavor.
• 😀 Grind size significantly affects extraction; too fine a grind leads to over-extraction and bitterness, while too coarse a grind can result in weak coffee.
• 😀 Water temperature is key to avoiding bitterness—keep it around 88°C for light roasts and 90-94°C for medium roasts.
• 😀 Brew time plays a role in extraction; too long a brew time will cause bitterness, while too short may result in under-extraction.
• 😀 Experiment with intervals in brewing methods like V60, but avoid overdoing it to prevent over-extraction and bitterness.
• 😀 Finding the optimal balance between grind size, water temperature, brew time, and intervals is crucial to achieving a clean, non-bitter cup.
• 😀 Aim for a balanced brew: neither too fine nor too coarse grind, not too hot or too cold water, and a brew time that suits your chosen method.
• 😀 Adjust based on the roast profile; for light or light-medium roasts, use lower temperatures, while medium roasts can handle slightly higher temperatures.

Q & A

What are the common reasons for bitterness in coffee when brewing at home?

Bitterness in coffee can be caused by several factors, including the roasting profile, grind size, water temperature, brewing time, and intervals between pouring the water.

What are the different roasting profiles, and how do they affect the taste of coffee?

There are three main roasting profiles: light roast, medium roast, and dark roast. Light roast has higher acidity and fruity flavors, medium roast offers a sweeter taste with lower acidity, and dark roast is typically bitter, preferred by those who like stronger, more robust coffee.

Why is the light roast profile recommended for avoiding bitterness?

Light roasts are ideal for avoiding bitterness because they have less caramelization, retaining more of the natural sugars that produce sweet and fruity flavors without over-extraction or bitterness.

How does grind size affect the bitterness of coffee?

Grind size directly affects the brewing time. A finer grind increases the surface area, leading to longer brewing times, which may cause over-extraction and bitterness. Coarse grinds, on the other hand, result in shorter brewing times and less extraction.

What is the ideal water temperature for brewing coffee to avoid bitterness?

Water temperature should be below 90°C (194°F) for lighter roasts to prevent bitterness. For medium roasts, temperatures between 88°C (190°F) and 90°C (194°F) are recommended, and for darker roasts, temperatures above 90°C are suitable.

What happens if the water temperature is too high when brewing coffee?

High water temperatures can lead to over-extraction, where undesirable compounds are extracted from the coffee, causing it to taste bitter and harsh.

How does brew time contribute to bitterness in coffee?

Brew time affects the extraction process. A longer brew time increases the chance of over-extraction, leading to bitterness. If the grind size is too fine or the brewing time is too long, the coffee will become overly bitter.

What is the role of coffee brewing intervals, and how do they impact bitterness?

Brewing intervals involve multiple stages of pouring water during brewing. If too many intervals are used, over-extraction can occur, leading to bitterness. The ideal number of intervals depends on the grind size and roast profile.

How can adjusting grind size and brew time help reduce bitterness?

By using a coarser grind and controlling brew time, you can reduce the chances of over-extraction. This ensures a balanced extraction, avoiding the bitterness that arises from excessive extraction.

What should you do if your coffee is consistently too bitter despite using optimal settings?

If bitterness persists, double-check your roast profile, grind size, and water temperature. It's possible that the roast profile you're using isn't optimal for your brewing method, or the grind size may be too fine. Experiment with different settings to find the ideal balance.
