Brewing Espresso

In Italy, where espresso originated, the word means “instant” or “express.” This refers to a the unique brewing method that quickly forces hot water through a bed of very finely ground coffee. Espresso is prepared by the cup, each extraction should be thick, flavorful, highly concentrated a head known as the “crema”. The crema is layer of smooth tight bubbles that is the aromatic and creamy signature of good espresso.

The Four M’s

The key elements for making great espresso

Miscela (blend): The right blend of espresso is crucial; it should be complex combining body, richness, acidity and brightness. Old City Coffee makes two espresso blends. Our traditional Six Bean Espresso is delicate, complex and nuanced. Our Original Espresso Blend will appeal to those looking for a stronger, sharper taste.

Macinazione (grind): Grinding your beans to the correct consistency is critical. If the beans are ground too coarse, the espresso will be too watery and bitter; if ground too fine, there will be no coffee at all due to a clogged filter. When ground and packed correctly in the portafilter, you create the pressure necessary to make proper crema; the espresso will trickle through it like honey dripping off a spoon.  The correct grind for espresso varies from machine to machine. We suggest you grind until you can feel slight granules and the ground coffee packs but does not cake when pressed between your thumb and index finger. For typical home grinders (such as Krups) we recommend grinding small amounts of espresso, and through trial and error, finding the grind that is right for your machine.

If you choose to have your espresso ground at Old City Coffee, we will grind your espresso at #4 on a Ditting commercial grinder (an ideal setting for typical home espresso machines). In some cases, the ideal grind may be finer (a lower number) or coarser (a higher number). You are welcome to specify grind in increments of .5 (example, 4.5). Please specify your grind in the comments box on the order page.

Macchina (espresso machine): The quality of your espresso machine will determine the quality of your cup because it contributes to two other key factors; correct brewing temperature and pressure. These are of the utmost importance when brewing espresso.

Mano (the skilled hand of the barista): At home-this means you! The signs of a properly made espresso are a concentrated, sweet coffee aroma with crema that should be a thick, foamy, cocoa-colored head.

Espresso Brewing Tips

• Use only the freshest coffee beans.
• Grind coffee only as you need it.
• For a single shot: Use 6–8 grams of espresso per 1–1.5 fluid ounce.
• For a double shot: Use 15 grams of espresso per 2 fluid ounce.
• Brewing time for a single or double shot should be 20-30 seconds. We like 25 seconds.
• Keep your brewer clean. Oily residue will compromise the taste of your espresso.
• Experiment. It takes time and many test-runs to find the right combination of grind, measure of coffee, packing tension and amount of water.
