Key Terms and Definitions

• 15-Bar Pump: Refers to the pressure generated by the machine’s pump, considered optimal for espresso extraction by many.
• Espresso: A concentrated coffee beverage brewed by forcing hot water under high pressure through finely-ground coffee beans.
• Pump Espresso Machine: A type of espresso maker that uses an electric pump to create the necessary pressure for brewing.
• Ground Coffee: Finely ground coffee beans used in espresso machines, offering control over the coffee used.
• ESE Pods (Easy Serving Espresso): Pre-portioned, single-serving pods of ground coffee designed for use in compatible espresso machines.
• Portafilter: The basket that holds the ground coffee or ESE pod, which is then locked into the machine for brewing.
• Steam Wand: A nozzle that produces steam, used to heat and froth milk for milk-based espresso drinks.
• Crema: The reddish-brown foam that forms on top of a well-pulled espresso shot, indicating proper extraction.
• Thermoblock Heating System: A system that heats water quickly as it passes through a small chamber, allowing for rapid heat-up times.
• Descaling: The process of removing mineral deposits (scale) that build up inside the machine from water, which can affect performance and taste.

How it Works

• The De’Longhi Dedica EC685.B utilizes a 15-bar pump to draw water from its reservoir.
• Water is then heated rapidly by the Thermoblock heating system to an optimal brewing temperature, typically between 195-205°F.
• The hot water is forced under high pressure through the coffee grounds or ESE pod held within the portafilter.
• This high pressure extracts the soluble compounds from the coffee, creating a concentrated espresso shot.
• The pressurized flow through the coffee bed results in the characteristic crema on top of the espresso.
• For milk-based drinks, the steam wand draws hot water from the boiler and superheats it into steam.
• This steam is then directed into milk, agitating it to create microfoam and increase its volume.
• Users can select single or double shot options, controlling the amount of espresso brewed.
• The machine’s design allows for relatively quick brewing cycles once heated up.
• The brewed espresso then flows into a waiting cup placed beneath the spout.

What Affects the Result

• Coffee Freshness: Using freshly roasted and ground coffee beans is paramount for optimal flavor and aroma. Stale coffee will produce a flat, lifeless shot.
• Grind Size: Espresso requires a very fine, consistent grind. Too coarse, and the water will flow too quickly, resulting in weak coffee. Too fine, and the water may struggle to pass through, leading to bitterness.
• Coffee-to-Water Ratio: The amount of coffee grounds used relative to the amount of water is crucial. A common starting point for a double shot is around 18-20 grams of coffee for approximately 2 ounces of liquid espresso.
• Water Quality: Using filtered or bottled water can significantly improve taste and prevent mineral buildup within the machine. Tap water with high mineral content can lead to scaling.
• Water Temperature: While the machine controls this, inconsistencies can arise if the machine is not fully heated or if brewing too many shots in quick succession without allowing it to recover. The ideal range is generally 195-205°F.
• Tamping Pressure: For ground coffee, consistent and even tamping of the grounds in the portafilter is essential to create a uniformly dense puck for even water flow.
• Pump Pressure: The 15-bar pump is designed to provide sufficient pressure, but ensuring the machine is functioning correctly is key.
• Milk Frothing Technique: The angle and depth of the steam wand in the milk, along with the duration of steaming, will determine the quality and texture of the foam.
• Machine Cleanliness: Regular cleaning, especially of the brew group and steam wand, prevents old coffee oils and milk residue from affecting the taste of new brews.
• Brew Time: The duration the water is in contact with the coffee grounds. For a double espresso, this is typically around 25-30 seconds from the moment the pump starts.
• Pre-heating: Allowing the machine, portafilter, and cup to pre-heat helps maintain stable brewing temperatures for better extraction.

Pros, Cons, and When It Matters

• Pro: Compact Footprint: The De’Longhi Dedica EC685.B is exceptionally slim, making it ideal for small kitchens or limited counter space. This is a significant advantage for apartment dwellers or those who prefer a minimalist setup.
• Con: Learning Curve for Milk Frothing: While it has a steam wand, achieving café-quality microfoam for lattes and cappuccinos can take practice. This matters if you’re particular about your milk texture.
• Pro: Fast Heat-Up Time: The Thermoblock system means the machine is ready to brew in under a minute, perfect for busy mornings.
• Con: Limited Customization: Compared to more advanced machines, the Dedica offers less granular control over brewing parameters like temperature or pre-infusion. This is less of an issue for those who want simplicity.
• Pro: Versatility with Pods or Ground Coffee: The ability to use both ESE pods and your preferred ground coffee offers flexibility and choice.
• Con: Durability Concerns (Reported): Some users have reported issues with the longevity of certain components over time. Regular maintenance is key to mitigating this.
• Pro: Affordable Entry Point: It provides a relatively accessible way to start making espresso-based drinks at home without a major financial investment.
• Con: Small Water Reservoir: The water tank is on the smaller side, requiring more frequent refills, especially if you’re making multiple drinks.
• Pro: Simple Operation: The controls are straightforward, making it user-friendly for beginners.
• Con: Noise Level: Like many pump espresso machines, it can be quite noisy during operation.
• When it Matters: This machine matters for individuals or couples who want to make 1-2 espresso drinks daily, have limited counter space, and are willing to learn basic espresso and milk frothing techniques. It’s a step up from drip coffee but not a professional-grade machine.

Common Misconceptions

• Myth: 15 Bars is Always Better: While 15 bars is often cited, the actual pressure at the coffee puck is more critical and can be lower. Even 9 bars is considered ideal for espresso. The pump’s ability to maintain stable pressure is more important than the maximum number.
• Myth: Any Espresso Machine Makes Great Espresso: Espresso quality depends heavily on the coffee itself, the grind, and the user’s technique, not just the machine. A great machine with poor coffee or technique will yield poor results.
• Myth: ESE Pods are Inferior to Freshly Ground Coffee: ESE pods offer convenience and consistency. While they might not satisfy the most discerning enthusiasts, they can produce very good espresso, especially for beginners.
• Myth: A Milk Frother Guarantees Latte Art: Achieving latte art requires practice, a specific milk texture (microfoam), and pouring technique, regardless of the frother’s quality.
• Myth: Espresso Machines Are Difficult to Use: While some high-end machines have a steep learning curve, entry-level models like the Dedica are designed for user-friendliness.
• Myth: You Need Expensive Coffee for Good Espresso: While quality beans matter, you don’t need the most expensive beans. Freshness and proper grind are often more impactful than the price tag.
• Myth: Descaling Isn’t That Important: Mineral buildup from water can clog the machine, affect heating, and alter the taste of your coffee. Regular descaling is crucial for performance and longevity.
• Myth: All Espresso Tastes Bitter: Bitterness in espresso is usually a sign of over-extraction, often due to too fine a grind, too high a temperature, or too long a brew time.
