Coffee Brewing: Turkish, Espresso, French Press, V60 and Others
From the cezve to the V60, from the AeroPress to espresso, eight different brewing methods worldwide, eight different sciences. A guide to the UNESCO ritual of Turkish coffee, SCA standards, and how to start with each method at home.

Coffee is the drink prepared by more different methods than any other in the world. In Türkiye it is simmered in a cezve, in Italy it comes out of an espresso machine at 9 bars of pressure, in Japan it drips slowly through a V60 filter, in France it is pressed in a French press, in the US it is brewed quickly in an AeroPress. Each method is a different chemical process, a different flavour profile, a different ritual. This article explains eight different methods with their scientific background and practical application.
The science of coffee extraction
A coffee bean contains more than 1000 aromatic compounds. Extracting them with water is a chemical dissolution process. Grinding, temperature, time and ratio are the four main variables that control this process.
Surface area effect: grinding the same amount of coffee finely dramatically increases the surface area, and extraction accelerates. Coarse grinding, on the other hand, is slow and requires a long brew. That is why different methods require different grind sizes; it is the grind size that defines the method, not the coffee type.
Extraction ratio: according to the Specialty Coffee Association, optimum is in the range of 18 to 22%. This is the dissolved material extracted from the coffee divided by the coffee dose. At the same time, the brewed coffee aims for TDS (Total Dissolved Solids) of 1.15 to 1.55%, the proportion of dissolved material in the liquid. Two separate metrics, different concepts. Below the range, "under-extracted" (weak, sour); above it, "over-extracted" (bitter, harsh). All methods aim to land in this window with different parameters.
extraction yield
Basic SCA ratio: 1:16 to 1:18 (coffee to water by weight). So 20 g of coffee to 320 to 360 g of water. This range is the starting point of many filter methods.
Optimum temperature: 90 to 96°C. Boiling water (100°C) breaks down coffee molecules and increases bitterness. Below 85°C, extraction is insufficient.
The scope of protection is not the food but the ritual: placing the cezve on the stove, watching the foam, reading the fortune in the cup, hospitality to the guest, and the bride's coffee preparation test at the proposal table. A social fabric stretching back to 16th-century Ottoman times.
Technical summary:
Grind: very fine, like dust (Turkish grind, 100 to 200 microns).
Cezve: copper or stainless, narrow base, slightly wide mouth. Volume 150 to 300 ml.
Ratio: 1 cup = 1 tablespoon (~7 to 8 g) of coffee + 1 cup (80 to 100 ml) of cold water + sugar as preferred.
Heat: low to medium, slow warming is critical.
Foam: the foam that swells on the surface before the coffee boils is the symbol of the ritual. Served as soon as it foams, heated rather than boiled.
Service: alongside the cup, a glass of water and a small lokum. Briefly rested before drinking; the grounds settle to the bottom.
Three-foam theory: by classical tradition, the ideal Turkish coffee is made with foam that rises three times. In modern barista practice, distributing the once-risen foam as a thin layer into the cup is also acceptable. The grounds should not pour fully into the cup; some stay in the cezve.
The fortune tradition: after drinking, the cup is turned over, the grounds slowly slide; once cooled, the cup is opened and a fortune is read from the shapes inside. This ritual of Turkish social life is an important part of the UNESCO inscription.
Espresso: pressure and speed
Espresso was invented in Italy in 1901. What sets it apart from other methods is being pulled under high pressure: hot water at 9 bars (nine times atmospheric pressure) passes through finely ground coffee in 25 to 30 seconds.
Technical parameters:
Grind: very fine (200 to 400 microns), thicker than dust.
Ratio: a single shot of espresso uses about 7 to 9 g of coffee with 14 to 20 ml of water (1:2, classic standard); a double shot uses 16 to 20 g of coffee with 32 to 40 ml of water (1:2). For a lungo or americano, more water (1:3 to 1:4). A much more concentrated ratio than the other methods.
Temperature: 90 to 96°C.
Pressure: 9 bar (traditional); modern machines run 6 to 9 bar.
Time: 25 to 30 seconds.
Crema: the golden-brown foam layer on top, formed by CO₂ release at high pressure.
Home espresso machines range between 10,000 and 100,000 TL. Manual lever machines (La Pavoni) are a cheap entry; automatic ones are easier but expensive. Pod machines (Nespresso) are a compromise; the quality is not at espresso level, but the use is easy.
French press: steep plus plunger
French press is of French and Italian origin (patent 1852, Paris), a simple method where coffee flavours come out rich. Coffee waits in direct contact with water for 4 minutes, then the grounds are pressed down with a piston and metal filter.
Technique:
Grind: coarse (~1290 microns), large granular.
Ratio: 1:16 to 17; so 30 g coffee plus 500 g (480 to 510 ml) water.
Temperature: 93 to 95°C.
Time: 4 minutes (some baristas extend to 6).
Wet first: wet the coffee with a little water 30 seconds before, to release gas.
Stir + turn: stir the foam that forms on the surface at 1 minute.
Press: after 4 minutes, lower the piston slowly; pressing fast stirs the grounds.
French press gives an oily, dense, rich coffee. Without paper filter, coffee oils (diterpenes) pass into the cup. For some these oils are rich flavour; for others a cholesterol concern. Research has shown filtered coffee to be safer in cholesterol terms.
V60: Japanese pour-over mastery
V60 is the cone-shaped pour-over coffee brewer released by Japanese Hario in 2004. It became the most popular pour-over method in modern specialty coffee.
Technique:
Grind: medium-fine (400 to 700 microns), the size of salt crystals.
Ratio: 1:16 to 17; typically 15 g coffee plus 240 to 250 g water.
Temperature: 93 to 95°C.
Total time: 2:30 to 3:30 minutes.
Bloom (initial wetting): pour twice the coffee weight in water (30 g water for 15 g coffee), wait 30 seconds. This releases CO₂ and ensures homogeneous extraction.
Pour technique: pour in 3 to 4 stages, 50 to 80 g each. Move in circular motion from the centre outward.
Filter: paper; wet with water before use (so the filter taste does not pass to the coffee).
V60 brings out clean, bright, aromatic notes. Ideal for specialty coffees with pronounced fruit and acid notes.
AeroPress: flexible plus fast
AeroPress was invented in 2005 by Aerobie. It resembles a large syringe and combines both pour-over and press characteristics.
Technique (standard method):
Grind: medium (300 to 600 microns); AeroPress's strength is here: different grinds give different results.
Ratio: 1:14 to 16, a more concentrated coffee.
Temperature: 80 to 92°C (lower than the standard methods; AeroPress extracts coffee richly).
Time: 1 to 2 minutes total (press included).
Inverted method: the AeroPress is flipped upside down, coffee and water steep inside, then it is righted and pressed. Provides a longer steep time.
The AeroPress's strength is in being universal: home, camp, office, travel. Compact, easy to clean, with paper filter or metal filter options.
Chemex: glass aesthetics plus a cleaner cup
Chemex was invented in 1941, a bottle-funnel hybrid glass coffee brewer. It uses a thick paper filter (thicker than V60), giving a cleaner and lighter cup.
Technique:
Grind: medium-coarse (700 to 1000 microns).
Ratio: 1:16 to 17.
Temperature: 93 to 96°C.
Time: 4 to 5 minutes (longer than V60, the filter is thick).
Thick filter: holds more oils and fines than V60, gives a cleaner cup.
The Chemex's claim is "not better coffee, but cleaner coffee." With its minimalist design, modern coffee houses prefer it.
Moka pot: an Italian classic, the home espresso
Moka pot (invented in 1933 by Bialetti) is the home espresso alternative. Water goes in the bottom chamber, coffee in the middle; once heated on the stove, steam pressure pushes water up through the coffee.
Technique:
Grind: fine (between espresso and medium, 300 to 450 microns).
Ratio: fixed by moka pot size (full chamber, small concentrated shot).
Temperature: 85 to 95°C (no full control).
Pressure: 1 to 2 bar (a tenth of espresso pressure).
Moka pot delivers a mini-espresso; a full crema does not form, but the coffee comes out concentrated. Cheap (200 to 500 TL), durable, standard in Italian homes.
Grind size guide
The most critical factor that defines the method is the grind size.
Dust (extra fine): Turkish coffee (100 to 200 microns). Not felt between fingers, powder-like.
Fine: espresso, moka pot (200 to 400 microns). Fine sand texture.
Medium-fine: V60, AeroPress (400 to 700 microns). Table salt texture.
Coarse: French press, cold brew (1200+ microns). Large salt crystals like those on a salty simit.
Burr grinder vs blade grinder: a burr (grinding wheel) gives a uniform grind; a blade is inconsistent. If you want to brew quality coffee, a burr grinder is essential (1000 to 5000 TL). Blade grinders are insufficient for home use.
Water and ratio
In our article on water and the kitchen, we covered the effect of water hardness on coffee in detail. According to our water and kitchen article, the SCA recommendation is 50 to 150 ppm mineral, weighted toward magnesium. Filtered water or spring water dramatically increases coffee quality. Tap water (especially in hard-water regions such as Ankara) suppresses the coffee's true potential.
Ratio table (practical):
Turkish coffee: 1:10 to 12 (concentrated, traditional)
Espresso: 1:2 to 3 (very concentrated, small volume)
French press: 1:15 to 17
V60: 1:16 to 17
AeroPress: 1:14 to 16
Chemex: 1:16 to 17
Moka pot: fixed (device size sets it)
Drip coffee: 1:17 to 18
Measurement: a scale with gram accuracy is ideal for all methods. Estimating with tablespoons plus cups is unreliable.
Practical advice for home
If you are starting, a three-step roadmap:
1. French press first: cheap (300 to 800 TL), simple, forgiving. Ideal entry into the coffee world. Coarse grind, 4 minute steep, 1:16 ratio. Stay here 2 to 3 weeks until you get consistent results.
2. Then V60 or AeroPress: 500 to 1500 TL investment (V60 set plus glass jug plus filters). Cleaner, brighter coffee. Learn the bloom technique and pouring rhythm.
3. Burr grinder: without a grinder, specialty coffee is meaningless. Hand-crank (manual) models such as Hario Skerton, Timemore, Kingrinder are 800 to 2500 TL.
Extra tools:
Precise scale (0.1 g resolution): 200 to 500 TL
Gooseneck kettle (for V60 pouring): 500 to 1500 TL
Thermometer: built-in kettle 700 to 2000 TL
Total investment: a careful home barista setup runs 3000 to 8000 TL. At this level, you can brew better coffee than at most cafés.
Special notes for Turkish coffee
Grind must not be the supermarket dust version but freshly ground Turkish grind. If you grind at home, use the finest setting. At the spice grocer, ask for "Turkish coffee grind."
Bean choice: traditionally Yemen-imported mocha (Arabica) or Ethiopian coffee. Today, Brazilian Arabica is also widespread. Freshly roasted (2 to 4 weeks earlier), medium roast preferred.
Cezve material: copper is best (good heat conduction); stainless steel is a good alternative; enamel-coated copper also works. The narrow base, slightly wide mouth shape matters.
Sugar timing: stir into cold water at the start; do not stir during boiling. The cezve disturbs the foam on the surface.
Cup temperature: warm the cups in hot water before brewing; reduce the temperature drop when pouring. A small detail, but it matters.
Common mistakes
Brewing with boiling water (100°C). Damages proteins, increases bitterness. The target is 93 to 95°C, achieved by waiting 30 seconds after boiling.
Wrong grind. Fine coffee in a French press equals muddy and bitter coffee. Coarse coffee in espresso equals fast flow and weak coffee. Grind must match method.
Not using enough coffee. The "let it be economical" 1:20 ratio yields watery coffee. Ratios below the SCA standard do not extract.
Boiling Turkish coffee. The classic is removed from the heat when the surface foam swells; it does not boil. Over-boiling evaporates the oils and weakens flavour.
Reusing filters. V60 and Chemex paper filters are single-use. Left wet they mould; the burnt paper taste passes into the coffee.
Stale coffee. After 2 weeks from roasting, aromas fade quickly. After 4 weeks it is considered "stale." An airtight container plus room temperature (not the fridge) is the recommended storage.
Closing word
Brewing coffee is a science-and-art mix. Eight methods, eight different parameter combinations, eight different flavour profiles. There is no single "right" way for all; taste preference and habit are the deciders. But every method has its own internal discipline: the right grind, the right ratio, the right temperature, the right time. These four parameters change from method to method, but the logic is the same.
While Turkish coffee lives on as a cultural treasure under UNESCO protection, V60 and AeroPress operate as representatives of modern specialty coffee. That two worlds can pull such different results from the same bean is the proof of coffee's universality.
