Water distribution - Import export

Your espresso may be watery for various reasons. One possible reason is that your grind may be too fine. If the grind is too fine, under-extraction happens because water has difficulty flowing through the coffee grounds to extract all the flavors. Another possible reason for a weak espresso is a machine’s uneven water distribution over coffee grounds. Uneven water distribution will cause over-extraction on some parts of the grounds and under-extraction on others resulting in a watery-tasting espresso. Tamping the coffee grounds too much could also result in watery espresso. If the grounds are tamped too firmly, water would have difficulty penetrating them to extract all the flavors, hence the watery taste. You can troubleshoot these variables to figure out what is making you pull thin espresso shots.

The best drip coffee is a matter of personal preference, but some factors that can affect the taste and quality of drip coffee include the quality of the coffee beans, the grind size, the water temperature, and the brewing time. It's important to use freshly roasted, high-quality beans and to grind them just before brewing. The grind size should be appropriate for drip brewing, which is a medium-coarse grind. The water temperature should be between 195-205°F (90-96°C) and the brewing time should be between 4-6 minutes. Additionally, using a good quality coffee maker with a showerhead or evenly distributed water flow can help to ensure that the coffee is brewed evenly and the flavor is well-developed.
