What to check first

Brewer type and filter type

You’ll need an espresso machine for a true Raf. Drip coffee or French press just won’t cut it here. The fine grind and pressure are key. For espresso machines, make sure your portafilter and basket are clean.

Water quality and temperature

Use filtered water. Tap water can add off-flavors. For espresso, the water temperature needs to be just right, usually between 195-205°F. Your machine should handle this, but check the manual if you’re unsure.

Grind size and coffee freshness

This is crucial for espresso. You need a fine, consistent grind. Think powdered sugar, but not quite. Freshly roasted beans, ground right before brewing, make a world of difference. Stale coffee tastes flat, no matter what you do.

Coffee-to-water ratio

For a standard double shot of espresso, you’re typically looking at around 18-20 grams of coffee grounds for about 36-40 grams of liquid espresso. This is a starting point; adjust to your taste.

Cleanliness/descale status

A dirty machine makes bad coffee. Seriously. Milk residue can sour quickly. Scale buildup affects temperature and flow. Run a cleaning cycle regularly, and descale according to your machine’s recommendations. It’s a game-changer.

Step-by-step (brew workflow)

1. Grind your coffee beans.

• What to do: Grind fresh, high-quality beans to a fine espresso consistency.
• What “good” looks like: A fluffy, even mound of grounds.
• Common mistake: Grinding too coarse or too fine. Too coarse makes weak espresso; too fine chokes the machine. Use a burr grinder and dial it in.

2. Dose and tamp the portafilter.

• What to do: Fill the portafilter evenly with grounds and tamp firmly and level.
• What “good” looks like: A smooth, flat surface of coffee after tamping.
• Common mistake: Uneven tamping or not tamping hard enough. This leads to channeling, where water finds weak spots and bypasses coffee.

3. Brew the espresso shot.

• What to do: Lock the portafilter into your espresso machine and start the brew.
• What “good” looks like: A steady stream of dark, syrupy liquid, transitioning to a lighter color. Aim for 25-30 seconds for a double shot.
• Common mistake: Brewing too fast or too slow. Too fast is under-extracted (sour); too slow is over-extracted (bitter).

4. Prepare the milk pitcher.

• What to do: Pour cold, whole milk into a steaming pitcher. Add your sugar.
• What “good” looks like: Just enough milk to reach below the spout.
• Common mistake: Overfilling the pitcher. You need room to create foam.

5. Warm the milk with sugar.

• What to do: Gently heat the milk and sugar mixture. Some people do this on the stove or by briefly running hot water into the pitcher. The goal is to dissolve the sugar and warm the milk slightly before steaming.
• What “good” looks like: The sugar is dissolved, and the milk is warm to the touch, but not hot.
• Common mistake: Overheating the milk before steaming. This can scald the milk and make it harder to get good microfoam.

6. Steam the milk.

• What to do: Submerge the steam wand just below the surface of the milk to introduce air (stretching), then lower it slightly to create a vortex (texturing).
• What “good” looks like: A low, gentle hissing sound as you stretch. Then, a quiet whirlpool motion as you texture. The milk should feel like wet paint.
• Common mistake: Making big, bubbly foam. This is too much air and not integrated. Aim for a smooth, glossy finish.

7. Groom the milk.

• What to do: Tap the pitcher on the counter to break any large bubbles and swirl the milk to integrate the foam and liquid.
• What “good” looks like: A smooth, glossy texture with no visible bubbles.
• Common mistake: Skipping this step. Large bubbles will ruin the creamy texture of your Raf.

8. Combine espresso and milk.

• What to do: Pour the steamed, sweetened milk into your freshly brewed espresso.
• What “good” looks like: A beautiful latte art pour, if you’re feeling fancy, or just a smooth integration of the two liquids.
• Common mistake: Pouring too aggressively, which can break the microfoam.

9. Stir gently.

• What to do: Use a spoon to gently stir the drink, ensuring the sweetened milk and espresso are fully combined.
• What “good” looks like: A uniform color and consistent sweetness throughout.
• Common mistake: Over-stirring or not stirring enough. You want it mixed, not churned.

10. Serve and enjoy.

• What to do: Serve immediately in a pre-warmed mug.
• What “good” looks like: A warm, aromatic, and delicious drink.
• Common mistake: Letting it sit too long. The texture and temperature are best right away.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using stale coffee beans	Flat, dull flavor, lack of crema	Use freshly roasted beans (within 2-3 weeks of roast date) and grind just before brewing.
Incorrect grind size	Under-extracted (sour) or over-extracted (bitter)	Use a burr grinder and adjust the setting until your espresso shot time and taste are right.
Poor tamping technique	Uneven extraction, channeling, weak flavor	Tamp with consistent pressure and ensure the coffee bed is level in the portafilter.
Over-steaming milk	Scalded flavor, stiff foam, poor texture	Steam milk until it reaches your desired temperature (around 140-150°F), focusing on microfoam.
Not dissolving sugar properly	Gritty texture, uneven sweetness	Ensure sugar is fully dissolved in the milk before or during the initial warming/steaming phase.
Using skim or low-fat milk	Thin texture, poor foam stability	Use whole milk for the best creamy texture and stable foam.
Not cleaning equipment regularly	Off-flavors, clogged parts, poor performance	Rinse portafilter after each shot, steam wand after each use, and descale your machine regularly.
Using tap water	Mineral buildup, off-flavors in coffee	Use filtered or bottled water for brewing and steaming.
Incorrect coffee-to-water ratio	Weak or overly strong espresso	Weigh your coffee and espresso output to achieve a consistent ratio (e.g., 1:2 for a double shot).
Serving too late	Foam dissipates, temperature drops, flavor dulls	Prepare and serve your Raf immediately after brewing.

Decision rules (simple if/then)

• If your espresso tastes sour, then try grinding finer because this increases extraction.
• If your espresso tastes bitter, then try grinding coarser because this decreases extraction.
• If your espresso flows too fast (under 20 seconds), then grind finer because your grounds are too coarse.
• If your espresso flows too slow (over 35 seconds), then grind coarser because your grounds are too fine.
• If your milk has large bubbles after steaming, then tap the pitcher firmly and swirl to integrate the microfoam because you likely introduced too much air initially.
• If your milk foam is stiff and separates quickly, then you probably overheated it or didn’t integrate it properly; try steaming less aggressively and swirling more.
• If your Raf tastes weak, then check your coffee-to-water ratio and ensure you’re using fresh beans and the correct grind size.
• If your machine is making strange noises, then check the water level and ensure it’s properly descaled because buildup can cause issues.
• If your coffee tastes “off” or metallic, then it’s likely your water quality; switch to filtered water.
• If your Raf isn’t sweet enough, then add a bit more sugar to the milk before steaming next time.
• If your Raf is too sweet, then reduce the sugar amount in the milk for your next brew.

FAQ

What is a Raf coffee drink?

A Raf is a creamy, sweet, espresso-based drink originating from Russia. It’s made with espresso, steamed milk, and sugar, often with vanilla syrup, creating a rich and smooth beverage.

Can I make a Raf without an espresso machine?

Technically, you can’t make a true Raf without espresso. The unique flavor comes from the espresso base. You could try using very strong coffee, but it won’t be the same.

What kind of milk is best for a Raf?

Whole milk is generally recommended for Rafs. It froths beautifully, creating a rich, velvety texture that complements the espresso and sweetness perfectly.

How much sugar should I use?

This is really up to your personal preference. A common starting point is about 1-2 teaspoons of sugar per drink, dissolved into the milk before steaming. You can always add more.

How do I get that smooth, velvety milk texture?

The key is proper steaming technique. Introduce air briefly at the start to stretch the milk, then submerge the wand to create a vortex that breaks down larger bubbles into microfoam. Swirling the milk afterward is also crucial.

Can I add flavorings to a Raf?

Absolutely. While traditional Rafs might just use sugar, vanilla syrup is a popular addition. You could also experiment with other syrups like caramel or hazelnut.

What’s the difference between a Raf and a latte?

A Raf is typically sweeter and has a richer, more integrated texture due to the way the sugar is incorporated and the milk is steamed. Lattes often have a more distinct layer of foam on top.

How important is coffee freshness for a Raf?

Very important. Freshly roasted and ground coffee beans are essential for a vibrant espresso flavor, which forms the base of your Raf. Stale beans will result in a dull, lifeless drink.
