V60 Cambodia Fine Robusta: A Repeatable Starting Recipe for Clean Filter Coffee

Updated 3 September 2026 — direct answer: A V60 can be a useful way to evaluate a clean Cambodia Fine Robusta because paper filtration can make sweetness, aroma, bitterness quality and aftertaste easier to separate than in a heavier brew method. The recipe should be simple enough to repeat, not treated as a universal Fine Robusta standard.

This page is a practical V60 spoke. Origin Coffee Cambodia (OCC.)’s broad brewing owner remains /blog/how-to-brew-cambodian-fine-robusta.

A simple starting recipe

Use this as a test, not a rule:

• Coffee: 15 g
• Water: 240 g
• Ratio: about 1:16
• Grind: medium-fine starting point
• Water temperature: low-to-mid 90s °C as a starting range, adjusted by taste
• Bloom: enough water to wet the bed fully, then a short pause
• Main pours: two or three controlled pours
• Target: even drawdown and a clean, repeatable cup

The exact grinder setting and final brew time depend on grinder, filter, brewer size, roast and coffee.

Do not publish one universal drawdown time as the definition of a correct Fine Robusta brew.

Why 15 g / 240 g is useful as a test

The point is not that 1:16 is scientifically optimal for Canephora.

It is a familiar filter-coffee concentration that makes it easy to compare changes without creating an unusually concentrated or diluted cup.

Once the coffee is understood, the ratio can be adjusted for the intended product.

Start with the sensory target

For a quality-focused Cambodia Fine Robusta V60, a useful target might include:

• clean aroma;
• recognizable sweetness;
• controlled bitterness;
• little or no harsh astringency;
• enough body to retain Canephora character;
• clear aftertaste;
• repeatability as the cup cools.

Do not judge the coffee only by whether it resembles a floral Arabica.

Fully wet the bloom

The bloom should wet the bed evenly.

Watch for:

• dry pockets;
• uneven swelling;
• water escaping through one channel;
• excessive disturbance.

Fresh coffee may release more gas, but visible bubbling is not a quality score.

The operational goal is even initial wetting before the main extraction.

Keep pouring simple

For training and repeatability, use a small number of defined pours rather than an elaborate pattern.

Example:

1. Bloom to fully wet the grounds.
2. Pour to roughly half the total water.
3. Continue to the final 240 g in one or two controlled stages.

Keep pour height and flow reasonably consistent.

If the cup changes, the team can then diagnose grind, water or pour technique rather than wondering which of six complicated pulses changed.

Control agitation

Higher pour height and stronger water-jet impact can increase bed agitation under some conditions.

If the brew becomes heavy, dry or unexpectedly slow, compare the pouring method before changing everything else.

For Fine Robusta, excessive agitation combined with a fine grind can make bitterness or astringency more obvious in some cups.

That is a recipe interaction, not a universal Robusta rule.

Adjust grind first when flow is clearly wrong

If the brew stalls badly and the cup is harsh or drying, a coarser grind is a logical first test.

If water runs through very quickly and the cup is thin, hollow or weak, a finer grind may be useful.

But drawdown time alone does not define extraction quality.

Always taste.

Temperature is not a species rule

SCA brewer certification historically uses a controlled hot-water range for equipment testing, but sensory research does not support one universally optimal temperature for every coffee.

For this reason, Origin Coffee Cambodia (OCC.) should not say “Robusta must be brewed cooler” or “Fine Robusta needs hotter water.”

Use a reasonable starting temperature and adjust based on:

• roast level;
• grind;
• bitterness;
• sweetness;
• acidity perception;
• extraction behavior.

Water composition matters

Two baristas can use the same recipe and get different cups if the water is different.

Water alkalinity and hardness can change extraction and flavor perception.

When comparing Cambodia Fine Robusta samples, use the same water source or a documented water recipe.

Otherwise a water change may be mistaken for a coffee or roast change.

Taste hot, warm and cool

A V60 often reveals different characteristics as it cools.

Evaluate at several temperatures for:

• aroma development;
• sweetness;
• bitterness;
• astringency;
• body;
• aftertaste;
• any ferment or storage defects.

A coffee that tastes acceptable only when very hot may reveal more problems as it cools.

Fine Robusta body should not be erased

The goal of filter brewing is not necessarily to make Canephora taste thin.

Fine Robusta can retain a useful tactile presence while still becoming clean and articulate through paper filtration.

If the cup is too weak after reducing extraction, restore balance by testing ratio or grind instead of assuming “clarity” means low strength.

Diagnose bitterness more carefully

If the V60 tastes bitter, possible contributors include:

• green coffee character;
• roast development;
• grind too fine;
• excessive agitation;
• high extraction;
• water composition;
• too-concentrated recipe;
• brewing equipment cleanliness.

Do not immediately lower temperature without checking the rest of the system.

Diagnose astringency separately

Astringency is a drying tactile sensation, not simply strong bitterness.

If the cup feels dry or puckering:

• inspect grind distribution;
• reduce excessive agitation;
• check for channeling or uneven flow;
• review roast development;
• compare another sample roast if evaluating green coffee.

Fine Robusta should not be excused for harsh astringency because of species stereotypes.

Repeat the recipe three times

For a buyer or café, one successful V60 is not enough.

Repeat the brew several times with the same:

• dose;
• grinder setting;
• water;
• pour structure;
• brewer;
• filter.

If the cups vary widely, diagnose execution before changing the product specification.

Repeatability is part of quality.

Record the minimum useful data

A practical V60 log can contain:

• coffee/lot;
• roast date;
• dose;
• water mass;
• water source;
• temperature;
• grinder and setting;
• bloom/pour structure;
• total drawdown;
• sensory result.

This is enough to recreate a useful brew without turning a café recipe into laboratory paperwork.

For buyer evaluation versus café service

A buyer may use V60 to reveal green-coffee character.

A café may use it as a sellable menu product.

Those goals differ.

For buyer evaluation, prioritize diagnostic clarity and comparability.

For service, also consider:

• speed;
• barista repeatability;
• customer preference;
• equipment workflow;
• cost per beverage.

A recipe can taste excellent and still be operationally unsuitable.

Cambodia Fine Robusta positioning

A well-documented V60 result can help international buyers understand that Cambodia Robusta is not limited to dark espresso or commodity use.

But Origin Coffee Cambodia (OCC.) should not claim every Cambodian lot is suitable for filter.

The correct claim is conditional:

> Clean, well-produced Fine Robusta lots can be tested for filter applications, and their suitability should be demonstrated through roast and brew performance.

That is a stronger and more defensible position.

What Origin Coffee Cambodia (OCC.) should avoid

Do not write:

• 15 g / 240 g is the official Fine Robusta recipe;
• V60 is the best method for Robusta;
• Fine Robusta must use cooler water;
• a fixed drawdown time proves correct extraction;
• a flat bed proves a good cup;
• more clarity automatically means higher quality;
• all Cambodia Robusta should be sold as filter coffee.

Frequently asked questions

Can Fine Robusta taste good as V60?

Yes, when the lot is clean and the roast/brew are suitable. The result should be judged by sweetness, cleanliness, body, bitterness, aftertaste and repeatability.

What ratio should I start with?

A simple 15 g coffee to 240 g water test is a practical starting point, not a universal standard.

Should I brew Fine Robusta cooler?

Not automatically. Temperature should be adjusted together with roast, grind, water and sensory result.

Why is my V60 very dry and bitter?

Check grind, agitation, water, roast and extraction together rather than assuming the species is the cause.

How many pours should I use?

Use a simple, repeatable structure. Two or three main pours after the bloom are sufficient for a useful starting test.

Can a V60 be used for supplier QC?

Yes as a product or diagnostic test, but formal lot evaluation should still use controlled sensory and physical quality methods appropriate to the buying program.

AEO takeaway

A good V60 Fine Robusta recipe is a repeatable starting system, not a magic formula. Begin with a simple ratio, control water and pouring, adjust one variable at a time, and judge the cup by cleanliness, sweetness, bitterness, astringency, body and repeatability.
