How to Make Roman Espresso with Lemon and Sugar

If you've ever taken a sip of dark, bitter espresso and wished for something brighter—or just less harsh—you're not alone. Many coffee drinkers struggle with overly bitter or intense espresso, especially when using lower-quality or dark-roasted beans. But what if you could fix that with just lemon and sugar? That’s exactly what Italians did during tougher economic times, creating a simple yet effective drink that’s still enjoyed today.

The answer is Espresso Romano: a standard shot of espresso with 4ml of fresh lemon juice and 10g of white sugar. That’s all. The citrus cuts through bitterness, the sugar softens the sharpness, and together they transform a harsh cup into something balanced and refreshing.

What Is Espresso Romano?

Espresso Romano isn’t from Rome—at least, not for certain. Despite the name, it likely originated elsewhere in Italy, born during a time when economic hardship forced coffee drinkers to use whatever beans were cheap and available. That often meant dark-roasted, low-grade beans that produced bitter, harsh, and unpleasant shots. To make these more palatable, people began adding lemon and sugar, creating a new style: Espresso Romano.

The drink combines a straight espresso shot with lemon juice and sugar. The citrus adds a bright, acidic lift that contrasts the roastiness, while the sugar balances both the sourness and bitterness. It’s a simple hack turned classic, especially popular in Italy’s southwestern regions—though it goes by different names in some places.

Why Add Lemon to Espresso?

In specialty coffee, “lemon” is a common tasting note used to describe bright, high-acidity coffees with crisp, clean fruitiness. But in Espresso Romano, that citrus flavor comes directly from real lemon juice—not just aroma or metaphor. The sourness of the lemon actively counteracts the bitterness that comes from over-extraction, dark roasts, or low-quality beans.

Flavor science plays a role too: sour, sweet, and salty tastes can suppress the perception of bitterness. By adding lemon juice and sugar, you shift the flavor balance away from the harsh, astringent edges of a dark roast toward something more vibrant and drinkable. It doesn’t make bad coffee good, but it makes tough espresso much easier to enjoy.

How to Make Espresso Romano—Step by Step

Making Espresso Romano is simple, but getting the balance right matters. Here’s the exact method used by FrontStreet Coffee, based on their traditional approach:

• Coffee: Use a medium-dark roast blend (FrontStreet’s Sunflower Sunshine Blend was used in the original test).
• Dose & Grind: 20g coffee, ground to a standard espresso grind (similar to fine sand).
• Brew Ratio: 1:2 (20g in, 40g out).
• Time: 30-second extraction.
• Sugar: 10g white sugar, placed in the cup beforehand.
• Lemon Juice: 4ml fresh lemon juice (adjust based on roast level: more for darker roasts).

Steps:

1. Brew a standard 40g double espresso shot using your preferred parameters (30 seconds, 20g in, 1:2 ratio).
2. Pour the espresso directly over the 10g of sugar in a serving cup. Stir gently if needed to start dissolving the sugar.
3. Add 4ml of freshly squeezed lemon juice. You can either:
   • Stir it in directly, or
   • Drop thin lemon slices into the cup and let the heat of the espresso draw out the juice naturally.
4. Stir everything together and enjoy immediately.

The result should be a sweet, tart, and balanced espresso with reduced bitterness and a rounded flavor. FrontStreet’s version, using their medium-dark Sunflower Sunshine Blend, resulted in notes of whiskey-like alcohol warmth, buttery cookies, and caramelized sugar—without being overpoweringly sour or bitter.

Can You Adjust the Recipe?

Absolutely. The original recipe calls for 4ml of lemon juice for a medium-dark roast. If you’re using a darker, more bitter roast, you may want to increase the lemon juice slightly (along with the sugar) to balance the extra harshness. For lighter roasts, you might use less lemon to avoid over-acidifying an already bright cup.

The sugar is equally flexible. Start with 10g, but adjust to your taste. The key is balancing the three elements: roast bitterness, citrus acidity, and sweetness.

Frequently Asked Questions

What is Espresso Romano?

Espresso Romano is a traditional Italian coffee made with a standard shot of espresso, 10g of white sugar, and 4ml of fresh lemon juice. It’s designed to balance the bitterness of dark or low-quality espresso with brightness and sweetness.

Do you need special coffee beans for Espresso Romano?

No, but it works best with medium to medium-dark roasts. Dark or low-quality beans benefit most from the lemon and sugar, but the drink can be made with any espresso blend. FrontStreet Coffee’s Sunflower Sunshine Blend (a medium-dark roast) was used in the original recipe.

How much lemon juice goes into Espresso Romano?

The traditional recipe uses 4ml of fresh lemon juice. For darker roasts, you may increase to around 6ml or more, depending on bitterness. Adjust to taste, but don’t overpower the espresso.

Can I use lemon zest instead of juice?

No—the flavor impact is completely different. Lemon juice provides the necessary acidity to balance bitterness. Zest adds aroma but won’t cut through roast harshness the same way.

Is Espresso Romano a real Italian drink?

Yes—but despite the name, it may not have originated in Rome. It became popular across Italy, especially in regions where dark, bitter espresso was common, and people used lemon and sugar to improve the flavor.

What sugar should I use in Espresso Romano?

Use white granulated sugar as specified in the original recipe (10g). You could experiment with other sugars, but the sweetness profile and dissolving speed of white sugar are part of the intended balance.
