1. Incorrect Coffee-to-Water Ratio

Mistake: Using too much or too little coffee can throw off the balance, affecting both flavor and strength.

Solution: Use a scale to measure your coffee beans and water. A common ratio to start with is 1:15, or 1 gram of coffee to 15 grams of water.

2. Inconsistent Grind Size

Mistake: An inconsistent grind can lead to uneven extraction, causing bitterness or under-extraction.

Solution: Invest in a quality grinder and experiment with grind size. For pour-over methods, the White Coffee Filter Paper V02 – 40 Pack for Pour Over Brewing can help achieve a smooth extraction.

3. Using Stale Coffee

Mistake: Coffee loses its complex flavors over time. Using old beans can result in a flat cup.

Solution: Buy fresh beans in small quantities and store them in an airtight container.

4. Water Quality

Mistake: Using unfiltered or hard water can introduce off-flavors to your coffee.

Solution: Use filtered water to avoid impurities that can mask complex coffee flavors.

5. Brewing Temperature

Mistake: Brewing with water that's too hot or too cold can affect extraction and flavor depth.

Solution: Aim for a water temperature between 195°F and 205°F (90°C to 96°C) for optimal extraction.

6. Inconsistent Dosing

Mistake: Not measuring the coffee grounds accurately can lead to inconsistency in taste.

Solution: Utilize tools like the COFFEE DOSING RING 58mm to ensure precise dosing without mess.

7. Neglecting Equipment Maintenance

Mistake: Dirty brewing equipment can harbor oils and residues, affecting brew flavor.

Solution: Regularly clean your brewing equipment following the manufacturer’s instructions.

8. Incorrect Brewing Time

Mistake: Over-brewing can lead to bitterness, while under-brewing can result in sourness.

Solution: Use a timer to manage your brew time accurately for your chosen brewing method.

9. Skipping the Bloom Step

Mistake: Failing to let your coffee bloom can hinder flavor development.

Solution: Pour a small amount of water over your grounds and let them sit for 30 seconds to release trapped gases before brewing.

10. Mistreating Milk Alternatives

Mistake: Using milk alternatives improperly can affect the texture and flavor of your latte.

Solution: Use barista-approved options like MILKLAB Almond Milk 1L or Box of 8 × 1L – Barista-Grade Dairy-Free Milk for better foam and taste.
