1咖啡冲泡基础知识

Before diving into specific methods, understanding the core variables that affect coffee extraction helps you troubleshoot any brew and adapt recipes to your taste.
Core brewing variables and their effects
VariableEffectAdjustment Tip
Grind sizeFiner = faster extraction, more body. Coarser = slower, lighter.Match to method; adjust if bitter (coarser) or sour (finer)
Water temperatureHotter = more extraction. Cooler = less.195-205°F (90-96°C) for most methods
Brew timeLonger = more extraction.Controlled by grind size and method
Coffee-to-water ratioMore coffee = stronger. Less = weaker.1:15 to 1:17 is common starting point
Water qualityMinerals affect extraction and taste.Use filtered water; avoid distilled or softened
FreshnessStale coffee = flat, dull flavor.Use within 2-4 weeks of roast date

The Golden Ratio

A 1:16 ratio (1 gram coffee to 16 grams water) is a reliable starting point for most methods. For a 12oz (340g) cup, that's about 21 grams of coffee. Adjust stronger (1:14) or weaker (1:18) to taste.
  • **Extra coarse** (peppercorns) — Cold brew
  • **Coarse** (sea salt) — French press, percolator
  • **Medium-coarse** (rough sand) — Chemex, clever dripper
  • **Medium** (regular sand) — Drip machines, siphon
  • **Medium-fine** (table salt) — Pour-over (V60, Kalita)
  • **Fine** (powdered sugar) — Espresso, Moka pot, AeroPress
  • **Extra fine** (flour) — Turkish coffee
Invest in a burr grinder over a blade grinder. Burr grinders produce consistent particle sizes, which means even extraction. A $40-80 hand grinder outperforms a $100 blade grinder for quality.

2Pour-Over Coffee

Pour-over produces clean, nuanced coffee that highlights origin flavors. It requires attention but rewards with exceptional clarity. Popular drippers include the Hario V60, Kalita Wave, and Chemex.

Hario V60 Recipe

1

Setup

Place filter in V60 on your server or cup. Rinse filter with hot water to remove paper taste and preheat. Discard rinse water.

2

Dose and grind

18g coffee, medium-fine grind (like table salt). Add to filter, shake to level bed.

3

Bloom

Start timer. Pour 40-50g water in circles, wetting all grounds. Wait 30-45 seconds as CO2 releases (grounds bubble).

4

First pour

At 0:45, pour slowly in circles from center outward, avoiding edges. Reach 150g by 1:15.

5

Second pour

At 1:15, continue pouring in circles. Reach 300g by 2:00.

6

Finish

Allow to drain completely by 3:00-3:30. If too fast, grind finer. If too slow, grind coarser.

Pour height and speed affect extraction. Pour from about 2-3 inches above the bed. Slow, steady pours are more controllable than fast ones. Use a gooseneck kettle for precision.

3French Press

French press produces a rich, full-bodied cup with oils and fine particles that paper filters remove. It's forgiving, doesn't require special equipment beyond the press, and makes multiple cups easily.

French Press Recipe

1

Preheat

Fill press with hot water to preheat. Discard before brewing.

2

Add coffee

30g coarsely ground coffee (for 450ml/15oz). Coarse grind prevents sludge and over-extraction.

3

Add water and stir

Pour 450g water at 200°F (93°C). Stir gently to ensure all grounds are wet. Start timer.

4

Place lid and wait

Place plunger on top (don't press) to retain heat. Wait 4 minutes.

5

Plunge slowly

Press plunger down slowly and steadily (20-30 seconds). Pressing too fast agitates grounds.

6

Serve immediately

Pour all coffee out right away. Leaving coffee in the press continues extraction, making it bitter.

  • **James Hoffmann method** — Don't plunge; after 4 min, break crust with spoon, scoop foam, wait 5+ more minutes, then plunge just below surface. Cleaner cup.
  • **Stronger brew** — Use 1:12 ratio or extend brew to 5-6 minutes.
  • **Lighter brew** — Use 1:17 ratio or reduce to 3 minutes.
  • **Cold French press** — Room temp water, steep 12-24 hours in fridge. Smooth concentrate.
French press coffee has more cafestol (a cholesterol-raising compound) than filtered coffee. If cholesterol is a concern, limit to occasional use or switch to filtered methods.

4爱乐压

The AeroPress is versatile, portable, and forgiving. It uses pressure and a paper filter to produce coffee somewhere between drip and espresso—concentrated but clean. Invented in 2005, it's become a cult favorite.

Why AeroPress?

Compact and travel-friendly. Nearly unbreakable. Forgiving of grind and timing variations. Produces excellent coffee. Easy cleanup. Under $40. There's a reason it has its own world championship.

Standard Method (Upright)

1

Setup

Place paper filter in cap, rinse with hot water. Attach cap to chamber. Place on sturdy mug.

2

Add coffee

15-18g coffee, fine to medium-fine grind. Add to chamber.

3

Add water

Pour 200-220g water at 200°F (93°C). Start timer.

4

Stir

Stir for 10 seconds to saturate all grounds.

5

Press

Insert plunger and press slowly and steadily for 20-30 seconds. Stop when you hear the hiss.

6

Serve

Total brew time ~1:30-2:00. Dilute with hot water if too strong (like an Americano).

Inverted Method (Popular Alternative)

1

Setup inverted

Insert plunger into chamber ~1 inch. Flip upside down so chamber is on top.

2

Add coffee and water

15g coffee, fine grind. Add 200g water. Stir.

3

Steep

Wait 1-2 minutes. This allows more contact time than upright method.

4

Attach filter and flip

Rinse paper filter, attach cap. Carefully flip onto mug. Let settle.

5

Press

Press slowly for 20-30 seconds.

The inverted method risks hot coffee spilling during the flip. The standard method is safer. Many award-winning AeroPress recipes use the standard method with longer steep times before pressing.

5意式浓缩咖啡基础知识

Espresso is concentrated coffee brewed by forcing hot water through finely ground coffee at high pressure (~9 bars). It's the base for lattes, cappuccinos, and Americanos. True espresso requires specialized equipment.

Basic Espresso Process

1

Dial in grind

Start with fine grind. Adjust based on shot time: too fast = finer; too slow = coarser.

2

Dose precisely

Use a scale. 18-20g is standard for a double shot. Consistency is critical.

3

Distribute and tamp

Distribute grounds evenly. Tamp firmly and level (~30 lbs pressure). Consistency matters more than exact pressure.

4

Pull the shot

Lock portafilter, start brew. Target 36-40g output in 25-30 seconds.

5

Evaluate

Too sour = under-extracted (grind finer, increase time). Too bitter = over-extracted (grind coarser, decrease time).

Espresso has the steepest learning curve and highest equipment cost. If you're starting out, consider Moka pot or AeroPress espresso-style brews as affordable alternatives before investing in a machine.

Moka Pot: "Stovetop Espresso"

The Moka pot (~$30) produces strong, concentrated coffee on the stove. It's not true espresso (lower pressure, ~1-2 bars), but makes rich coffee for Americanos or milk drinks. Use medium-fine grind, low heat, and remove from stove as soon as coffee finishes flowing.

6Cold Brew Coffee

Cold brew uses time instead of heat to extract coffee—typically 12-24 hours at room temperature or refrigerated. The result is smooth, sweet, low-acid coffee concentrate that's excellent over ice.

Basic Cold Brew Recipe

1

Grind coarsely

100g coffee, extra coarse (coarser than French press). Fine grind makes bitter, muddy cold brew.

2

Combine with water

Add 800g room temperature or cold filtered water. Stir to saturate all grounds.

3

Steep

Cover and steep 12-24 hours. Room temp = faster, more body. Fridge = slower, cleaner taste.

4

Filter

Strain through fine mesh, then through paper filter or cheesecloth. This removes silt.

5

Store

Keep concentrate refrigerated up to 2 weeks. Dilute 1:1 with water or milk when serving.

  • **Mason jar** — Simple, cheap, works fine for small batches.
  • **Toddy system** — Dedicated cold brew system with easy filtering. ~$35.
  • **Filtron** — Another dedicated system, larger capacity. ~$45.
  • **Hario Mizudashi** — Glass pitcher with built-in filter. Easy and elegant. ~$25.
  • **French press** — Works for small batches. Strain through paper after for cleaner result.

Japanese Iced Coffee (Flash Brew)

For brighter, more aromatic iced coffee, try flash brewing: brew hot pour-over directly onto ice. Use half your water weight as ice in the server, half as hot water for brewing. This preserves aromatics that cold brew lacks.

7滴滤咖啡机（全自动）

Drip coffee makers are convenient for making large quantities consistently. Quality varies wildly—cheap machines make mediocre coffee, while SCA-certified machines rival manual pour-over.
  • **Water temperature** — Should reach 195-205°F. Cheap machines often don't get hot enough.
  • **Shower head** — Should evenly saturate the coffee bed, not just the center.
  • **Brew time** — 4-6 minutes for proper extraction.
  • **Thermal carafe** — Keeps coffee hot without the glass carafe/hot plate that scorches coffee.

Optimizing Drip Coffee

1

Use fresh beans

Stale coffee = stale drip. Buy within 2 weeks of roast, grind just before brewing.

2

Correct grind

Medium grind for most flat-bottom basket filters. Slightly finer for cone filters.

3

Correct ratio

Start with 1:16 (60g coffee per 1 liter water). Adjust to taste.

4

Use filtered water

Tap water minerals and chlorine affect taste. Filtered or bottled spring water is better.

5

Pre-wet filter

Rinse paper filter with hot water before adding coffee. Removes papery taste.

6

Clean regularly

Descale monthly with vinegar or descaling solution. Old oils go rancid.

If you have a basic machine that makes mediocre coffee, grind quality may be your issue. Upgrade to a burr grinder before replacing the machine. A $40 grinder improves a cheap machine more than a $200 machine improves on bad grounds.

8水质至关重要

Coffee is 98%+ water. Using bad water makes bad coffee regardless of beans or method. Understanding water basics makes a real difference.

Recommended useDaily brewingWhen tap is poorAvoid unless remineralized

Why Distilled Water Fails

Water needs minerals (calcium, magnesium) to extract coffee properly. Distilled or reverse-osmosis water lacks these, resulting in under-extracted, flat coffee. If you must use RO water, add mineral drops (Third Wave Water, Perfect Coffee Water) to remineralize.
Hard water (high mineral content) causes scale buildup in equipment and can over-extract coffee. Very hard water should be filtered or mixed with distilled to reduce hardness. If you see white scale in your kettle, your water is hard.
Ideal brewing water: 50-175 ppm TDS (total dissolved solids), pH 7.0, no chlorine. You can test with inexpensive TDS meters (~$15). Most filtered tap water falls in acceptable range.

9咖啡豆的选择与储存

Fresh beans are the foundation of great coffee. No brewing method can compensate for stale or poor-quality beans.
1
Days 3-7

Peak Flavor

Best window for most coffee. Espresso may need 10-14 days for CO2 to dissipate.

2
Days 7-21

Excellent

Still great quality. Most specialty coffee should be used in this window.

3
Days 21-30

Good

Starting to lose vibrancy. Still acceptable but noticeably less nuanced.

4
Days 30+

Declining

Oxidation accelerates. Coffee tastes flat, stale, and generic.

Roast levels and their characteristics

LightLight brown, dryBright, fruity, acidic, origin-forwardPour-over, AeroPress
MediumMedium brownBalanced, sweet, some origin + some roastAll methods
Medium-darkDark brown, slight oilRich, less acidity, chocolate/caramelDrip, French press, espresso
DarkDark/black, oilySmoky, bitter, roast-dominantEspresso blends, cold brew
  • **Airtight container** — Oxygen is the enemy. Use a container with a one-way valve or vacuum seal.
  • **Cool, dark place** — Heat and light accelerate staling. Avoid countertops near stove or windows.
  • **Never refrigerate** — Coffee absorbs odors and moisture fluctuates with door opening.
  • **Freezing works** — For long-term storage, freeze in single-use portions. Don't refreeze.
  • **Buy smaller quantities** — Better to buy fresh every 1-2 weeks than to stockpile.
Look for a roast date on the bag, not just an expiration date. Avoid coffee with no date—it's often old. Local roasters and specialty shops typically roast more recently than supermarket brands.

10酿造故障排除

Coffee not tasting right? Most issues come down to extraction—either too much or too little. Here's how to diagnose and fix common problems.
Common coffee problems and solutions
ProblemLikely CauseSolution
Sour, sharp, thinUnder-extractionGrind finer, brew longer, use hotter water
Bitter, harsh, astringentOver-extractionGrind coarser, brew shorter, use cooler water

Muddy, siltyToo fine grind / poor filteringGrind coarser, use better filters
Metallic, chemical tasteWater qualityUse filtered water, descale equipment
Papery tastePaper filter not rinsedRinse paper filters with hot water before use

Change One Variable at a Time

When troubleshooting, adjust only one variable between brews. If you change grind and ratio simultaneously, you won't know which fixed (or worsened) the problem. Grind size is usually the most impactful adjustment.
  • **Pour-over draining too fast** — Grind finer, pour slower, check filter seating.
  • **Pour-over draining too slow** — Grind coarser, check for clogging from fines.
  • **French press is murky** — Grind coarser, don't agitate during steep, try Hoffmann method.
  • **Espresso running too fast** — Grind finer, increase dose, check for channeling.
  • **Espresso running too slow** — Grind coarser, decrease dose, distribute more evenly.
  • **Cold brew is bitter** — Grind coarser, reduce steep time, use less coffee.

常见问题解答

对于初学者来说，最好的咖啡冲泡方法是什么？
法压壶对新手来说最友好——它不容易出错，无需任何技巧，而且能稳定地冲泡出美味的咖啡。爱乐压也是一个不错的入门选择，操作简单，功能也更加多样。等你熟练之后，可以尝试手冲，体验更丰富的风味层次。
我应该花多少钱买一台咖啡研磨机？
手摇磨豆机（40-80美元）在研磨质量方面优于任何刀片式磨豆机。为了方便起见，电动磨豆机的起价约为100-150美元，研磨质量尚可（例如Baratza Encore、OXO Brew）。制作意式浓缩咖啡则需要研磨更细的磨豆机（200美元以上）。磨豆机比冲煮设备更重要。
贵的咖啡味道更好吗？
并非总是如此。新鲜度比价格更重要——一袋12美元的本地烘焙商上周烘焙的咖啡豆，通常比一袋20美元的知名品牌几个月前烘焙的咖啡豆更好。话虽如此，无论价格如何，特级咖啡豆（真正意义上的品质等级）的口感通常都优于普通咖啡豆。
如何制作出更浓郁而不苦涩的咖啡？
与其延长冲泡时间或使用更细的研磨度，不如增加咖啡粉的用量（例如，提高咖啡粉与咖啡粉的比例，比如 1:14 而不是 1:16）。延长冲泡时间和使用更细的研磨度会增加萃取率，从而增加苦味。增加咖啡粉的用量可以提高咖啡的浓度，同时保持萃取平衡。
冷萃咖啡比热咖啡更健康吗？
冷萃咖啡的酸度略低（根据一些测量方法，酸度降低了67%），有些人觉得它对胃更温和。但是，由于浓缩程度更高，冷萃咖啡每份的咖啡因含量是普通咖啡的1.5-2倍。两者的抗氧化剂含量相近。差别微乎其微——选择你喜欢的就好。
