COMMON NANOPRESSO BREWING MISTAKES AND HOW TO FIX THEM

WACACO Nanopresso – compact portable espresso maker

Nanopresso has gained popularity among coffee lovers who enjoy brewing their own coffee on the go. While the Nanopresso offers convenience and the ability to create rich and flavorful espresso shots, it’s important to note that certain mistakes can impact the quality of the brew. In this article, we will discuss some common mistakes to avoid when using the Nanopresso, ranging from water temperature to grind size.

1/INCONSISTENT WATER TEMPERATURE

One of the most crucial factors in brewing espresso is maintaining the right water temperature. The Nanopresso relies on hot water to extract flavors from the coffee grounds effectively. To ensure consistency, it is recommended to use water at a temperature between 90°C and 96°C. Avoid using boiling water as it can scorch the coffee and result in a bitter taste. A reliable thermometer can help you achieve the ideal water temperature consistently.

2/INADEQUATE PREHEATING

Preheating the Nanopresso brewer is often overlooked but is essential for achieving optimal brewing conditions. Failing to preheat the device can lead to temperature loss during the brewing process. To preheat, rinse the Nanopresso with hot water by pumping water through the system without coffee grounds. This ensures that the brewer and the internal components are at the right temperature, allowing for a more consistent and flavorful extraction.

3/INCORRECT COFFEE GRIND SIZE

The grind size plays a vital role in the extraction process, affecting the taste and consistency of the espresso. Using the wrong grind size can result in under-extraction or over-extraction of the coffee. For the Nanopresso, it is generally recommended to use a fine to medium-fine grind, similar to the texture of table salt. Finer grinds can slow down the extraction, whereas coarser grinds may result in a weak brew. Experiment with different grind sizes to find the sweet spot that suits your taste preferences.

4/TAMPING TOO HARD OR TOO SOFT

Tamping is the process of compacting the coffee grounds in the filter basket to ensure even extraction. However, tamping with excessive force can lead to over-extraction, while insufficient tamping may result in under-extraction. Aim for a consistent and firm tamp, applying moderate pressure to create an even coffee bed.

5/NEGLECTING PROPER CLEANING

Maintaining cleanliness is essential for consistent brewing and to prevent any buildup of coffee residue or oils that can affect the flavor of future brews. After each use, disassemble the Nanopresso and rinse all the parts with hot water. Use a soft brush to remove any stubborn coffee grounds.
