How Should Espresso Coffee Beans Be Selected and Stored?

Espresso beans can be a blend or a single origin; neither is automatically better. Blends are built for balance and consistency across milk drinks, while single origins show a specific farm or region's character. Roast level, freshness and storage matter more than the blend-versus-single-origin label for what ends up in the cup.

For coffee beans for commercial use, consistency between batches is the practical priority, so many shops rely on a fixed blend recipe. At home, buy whole beans and grind just before brewing, since ground coffee loses aroma quickly. Keep beans sealed in the original bag with its one-way valve or in an airtight jar, in a dry, cool place, and use them within weeks of the roast date. Learning how to preserve coffee this way keeps flavor steady.

Espresso is both an extraction method and the name of a coffee beverage; it is the most frequently encountered and familiar type of coffee for the general public.

Espresso can refer both to an extraction method and to the name of a coffee beverage. As an extraction method, espresso is the most frequently encountered and most familiar method for ordinary consumers. Perhaps because it is so familiar, it actually gives rise to the most questions.

The most common questions among those who have just started learning about coffee are these: "How to select and store espresso beans"; "Are the beans used to make espresso a blend or a single origin"; "The roast level of espresso-roasted coffee beans"; "Are espresso blend beans specialty coffee?"; "Is it normal for espresso beans to be acidic?"

How to select and store espresso beans?

Front Street Coffee (FrontStreet Coffee) has always adhered to the principle of selling freshly roasted coffee beans, because only freshly roasted, freshly ground, and freshly extracted espresso will display a rich, full-bodied mouthfeel and a deep, aromatic coffee flavor. So that every customer can experience the charm of freshly roasted coffee, all coffee beans ordered online are shipped within 5 days of completing the roast.

Espresso beans can be stored sealed in their original packaging (with a one-way degassing valve) or in an airtight jar, kept in a dry, cool environment. Once coffee beans are ground into powder, aroma molecules are released more rapidly, so Front Street Coffee (FrontStreet Coffee) recommends buying whole beans and grinding with a grinder just before brewing.

Are the beans used to make espresso a blend or a single origin?

Both blends and single-origin coffees can be used to make espresso, and each has its own advantages and disadvantages.

The advantage of Front Street espresso blend beans is that they better stabilize the quality and flavor performance of every cup, with low cost; the disadvantage is a one-dimensional flavor—most espresso extracted from blend beans shows only a rich, full-bodied character. The advantage of single-origin beans is that they can give espresso a distinctive flavor; the disadvantages are lower extraction stability and higher cost.

Front Street Coffee (FrontStreet Coffee) uses blend beans to extract espresso for its daily store offerings, because compared with single-origin beans, blend beans can better stabilize the flavor and quality performance of every cup of espresso. Based on the taste needs of ordinary consumers, Front Street Coffee (FrontStreet Coffee) has also launched four Front Street espresso blend beans specially made for espresso.

"Front Street Coffee (FrontStreet Coffee) - Specialty Blend": an espresso bean dominated by nutty aroma. Made from Colombia washed coffee beans (30%) + Brazil semi-washed coffee beans (70%), it has nut, dark chocolate, and caramel flavors, meeting the daily needs of running a shop.

This cost-effective espresso bean is suitable for shop owners and home users who prioritize cost and have average flavor requirements.

The roast level of espresso-roasted coffee beans

In order for the coffee liquid extracted from espresso beans to display a rich, full-bodied mouthfeel, Front Street Coffee (FrontStreet Coffee) uses a medium-dark roast level. The longer the roasting time, the more carbon dioxide the coffee beans retain after roasting is complete.

The presence of carbon dioxide helps preserve coffee flavor, but too much carbon dioxide can also affect espresso extraction, so after receiving espresso beans, you can let them rest in the original packaging until 5-6 days after the roast date, allowing the beans to release carbon dioxide on their own through the one-way degassing valve on the package, stabilizing extraction.

Although light-roasted coffee beans are used by many pour-over coffees, the purpose is to allow the coffee, under pressureless drip extraction, to extract a richer sweet-tartness at a suitable ratio. But espresso is pressure-based extraction, and many sweet-tart substances that perform well in pour-over will show unpleasant sharp acidity under pressure and extremely high concentration.

At the same time, because light-roasted coffee beans have a short roasting time, there is not enough time to produce more caramelization reactions and bring out rich, full-bodied flavor substances. Therefore, espresso made from light-roasted coffee beans usually has a relatively thin mouthfeel and lacks body.

Are espresso blend beans specialty coffee?

Of course they are! As long as the coffee beans used in the blend meet the specialty coffee requirements for origin and as required by the SCA, both single-origin coffee and blend coffee count as specialty coffee beans.

Is it normal for espresso beans to be acidic?

Yes, it's normal~ The flavor expression of espresso mainly comes from the coffee beans themselves. Espresso may have acidity because the merchant used coffee beans with fruity acidity to make the espresso, perhaps single-origin beans or perhaps blend beans.
