Coffee Brewing 101

Manual brewing means making coffee yourself, with control over how you make it. You decide the coffee, grind size, water, temperature and brewing time, and each of these can change how the final cup tastes.

There are many ways to brew coffee manually. Pour Over, AeroPress, French Press, South Indian Filter and Moka Pot all work differently and produce very different cups. That’s part of the fun. You can start with a simple recipe and slowly figure out what works for you.

002

Things you need

Start with a kettle. A gooseneck kettle with temperature control gives you the most control over your brew. If you don’t have one, use a regular kettle with an external thermometer and a drip pot.

A grinder is worth having if you’re brewing with whole beans. Manual grinders are a good choice unless you’re making a lot of coffee. Good options range from around ₹4,000 to ₹30,000, including the AAshonee Classic Classic, Timemore C2S, 1zpresso J Ultra, and Comandante C40 MK4. If you prefer electric, the Baratza Encore is a good option.

A scale is also useful for measuring coffee and water consistently. Most coffee scales have a timer, but your phone works too. Depending on your brewing method, you’ll also need paper filters.

003

Grind size matters

Grind size is one of the variables we can control, whether we grind the coffee ourselves or buy it pre-ground. It affects how easily water moves through the coffee and, in turn, how the cup tastes.

Grinders usually have a range of settings, but the numbers aren’t universal. It’s better to understand the texture of the coffee rather than rely only on the number.

Very fine grounds feel like talcum powder, fine grounds resemble table salt, medium grounds are closer to sand, and coarse grounds are like rough sea salt. Finer grounds generally slow the water down and extract more, while coarser grounds allow water to pass through more easily.

004

How to start

Coffee and water are the two essentials. About 98% of your cup is water. Start with clean RO water. For a simple baseline, aim for a pH around 7 and TDS between 75–200.

For coffee, fresher is better. Buy good-quality roasted beans, grind them as needed, and store them dry and airtight. Buy smaller batches, especially for pre-ground coffee.

If you are in South India, choose coffee without chicory if you want to taste the coffee itself. Start without sugar. It’s the easiest way to notice its aroma and flavor.

There are different ways to make coffee. The method you use affects how the water and coffee interact, which changes the taste and texture of the cup.

French Press

French press is ideal if you’re looking for a strong cup of coffee. Personally, I’m not a huge fan of it, but it’s definitely popular.

The idea is pretty simple. You let the coffee grounds sit in hot water for a few minutes, then press them down to separate the grounds from the coffee. There’s no complicated technique involved. All you need is a French Press

Coffee15g
GrindCoarse
Water250ml at 90°C to 93°C
Time4 minutes
  1. Add the coffee to the French press.
  2. Pour in all 250ml of water and make sure all the grounds are saturated.
  3. Stir gently and place the lid on top without pressing the plunger.
  4. Let it steep for 4 minutes.
  5. Gently press the plunger down over 20 to 30 seconds.
  6. Pour immediately and enjoy.
006

Moka Pot

Moka pot makes an intense, strong coffee. All you need is the Moka pot itself. The idea is simple, but the way it works is fascinating. Water in the bottom chamber heats up and creates pressure, pushing the water up through the coffee grounds and into the top chamber. The result is a rich and concentrated coffee that’s slightly cloudy, with a strong aroma that can fill the whole room. I strongly recommend a Bialetti stovetop Moka pot over other brands and electric ones.

Coffee12g
GrindFine, like Table-salt
Water140ml, for a Bialetti 3-cup pot
Time2-3 minutes
  1. Fill the bottom chamber with hot water up to the safety valve, (around 140ml)
  2. Fill the basket with coffee, level it out gently, and don’t tamp.
  3. Screw the pot together and put it on medium-low heat.
  4. Once the coffee starts coming out, turn the heat down.
  5. Take it off when the stream gets lighter.
  6. Cool the bottom chamber under cold water, then pour and enjoy. Dilute if needed.
  7. Just rinse the pot after use. Skip the soap and let those coffee oils stay.
007

Pour Over

Pour over is a coffee brewing method where you slowly pour hot water over ground coffee held in a paper filter. You can use different pour-over devices, such as the Hario V60 (Plastic, Glass, Metal or Ceramic), Origami, and Switch Dripper, which sit directly over your cup or carafe. The water passes through the coffee and filter, leaving you with a clean and clear cup. Each dripper controls water flow differently, changing the final cup.

You need a filter paper, which holds the coffee grounds back and filters out most of the oils. Water temperature, how much you pour, and how evenly you pour can all make a difference.

Coffee15g
GrindMedium-fine, like fine sand
Water250ml at 92-94°C
Time2:30–3:30 minutes
  1. Rinse the paper filter with hot water and discard the rinse water.
  2. Add the coffee and gently level the grounds.
  3. Pour 50ml of water evenly over the coffee and let it bloom for 30–45 seconds.
  4. Slowly pour the remaining water in gentle circles until you reach 250ml.
  5. Let the water drain completely through the coffee bed.
  6. Give the dripper a gentle swirl, then pour and enjoy.

AeroPress

AeroPress is a brewing method that combines immersion brewing with pressure. You steep ground coffee in hot water inside the AeroPress, then press the brewed coffee through a paper filter and into your cup. You need an AeroPress or it’s travel friendly version AeroPress Go and a paper filter. Unlike pour-over, the AeroPress allows the coffee to steep before you press it through the filter.

There are many ways to brew with an AeroPress, but the clearest difference is how you position it: standard or inverted. In the standard method, it sits on your cup and the coffee is pressed straight through the filter. In the inverted method, it is turned upside down while the coffee steeps, so it doesn’t drain before you’re ready to press.

Coffee15g
GrindMedium-fine
Water240ml at 85°C
TimeAbout 2 minutes
PositionStandard
  1. Place a paper filter in the filter cap and rinse it with hot water. Discard the rinse water.
  2. Attach the filter cap and place the AeroPress upright on your cup.
  3. Add 15g of coffee.
  4. Pour 240ml of water at 85°C over the coffee, making sure all the grounds are wet.
  5. Stir gently and let the coffee steep.
  6. At around 2 minutes, press the plunger down slowly and steadily.
  7. Remove the AeroPress and enjoy.

See AeroPress Recipes for other recipes and variations.

South Indian Filter

South Indian Filter coffee uses a metal two-piece filter. Hot water slowly drips through the coffee into the lower chamber, making a strong decoction that is usually mixed with hot milk and sugar.

Coffee40 to 50g, medium-dark to dark roast.
Water120 to 200g (1:4 or 1:4.5)
Time15 minutes
  1. Add the coffee to the upper chamber and level it gently.
  2. Place the metal disk on top. It spreads the water evenly. Don’t tamp.
  3. Add 30ml of hot water and wait 1 minute.
  4. Pour the remaining water slowly over the disk.
  5. Cover and let it drip undisturbed for about 15 minutes.
  6. Mix the decoction with hot water for black coffee, or hot milk and sugar for milk coffee.

For milk coffee, add ~3g sugar to the dry coffee before brewing to bring out the chicory’s sweetness. For copper filters, heat the upper chamber occasionally to clear the small holes. Video Recipe in Tamil, but you’ll understand how he makes it.

How to taste a cup

Tasting is personal. Smell the coffee, take a sip, and notice the flavour, texture, and what lingers after you swallow. Let it cool too, as sweetness, acidity, and other flavors become easier to notice.

The SCA Coffee Taster’s Flavor Wheel is a tool to help find words for what you taste, not a standard to match. Tasting notes are personal perceptions, not absolute descriptions, and they may differ from person to person.

011

Fixing a bad cup

A bad cup is usually a matter of extraction, strength, or both. Across moka pot, French press, AeroPress, South Indian filter, and pour-over, you can adjust five basic variables:

VariableWhat it changes
Grind sizeHow easily water extracts the coffee
Water temperatureHow quickly extraction happens
Coffee-to-water ratioHow strong the cup is
Contact timeHow long extraction continues
AgitationHow much the coffee is disturbed during brewing

Taste → Try this

If your coffee tastes…Try…
Sour or sharpGrind finer
ThinUse more coffee
Bitter or harshGrind coarser
Dry or astringentReduce agitation
Weak or wateryUse more coffee
Too strongUse more water
Sour and strongGrind finer
Bitter and weakGrind coarser
Make one small change, taste the difference, and keep adjusting until the cup feels right.

Few Random Things

  1. Focus on your taste preference. Don’t get too caught up in what someone else says is a good cup of coffee. If you like it, that’s what matters. You will slowly figure out what kind of coffee, roast, grind and brewing style you enjoy.

  2. Robusta is not bad coffee. There is a lot of talk about Arabica being better and Robusta being inferior. It is not that simple. Robusta can make a very good cup. Try different coffees and decide based on what you like.

  3. Reuse your Aeropress filter. You don’t have to throw away the paper filter after every cup. Rinse it properly and you can reuse it a few times. PS: I have tried a steel filter with the Aeropress, but it never worked for me.

  4. Be ready to experiment. There is no need to follow a recipe exactly every time. Change the grind size, water temperature, coffee-to-water ratio or brewing time and see what happens. Small changes can make a noticeable difference.

  5. Do have coffee earlier, if that affects sleep. If coffee affects your sleep, don’t drink it late just because you want another cup. Have it earlier in the day.

  6. Note down your experiments. When you are trying different coffees and recipes, write it down. A notebook is enough.
