Common Mistakes to Avoid When Making a Long Black

The long black is one of the simplest yet most beloved coffee styles in Australia. While it may look straightforward, the quality of a long black depends heavily on technique. A perfectly made one showcases the richness of espresso while preserving a smooth balance of flavour. However, many home brewers and even cafés fall into small but critical mistakes that can drastically affect the taste. If you’re keen on making a long black coffee at home, here are the most common pitfalls to avoid.

Using Stale or Poor-Quality Beans

The foundation of any great coffee lies in the beans. Using old or low-quality beans will produce a flat and bitter result, no matter how skilled your technique. Always opt for freshly roasted coffee, store it properly in an airtight container, and grind only what you need for immediate use.

Pouring Order Mistakes

Perhaps the biggest error when making a long black is mixing up the pouring order. Many mistakenly pull the espresso shot first and then add water, which disrupts the crema and creates a harsher taste. The proper method is to pour hot water into the cup first and then extract the espresso directly over the top. This ensures the crema sits beautifully on the surface, enhancing both aroma and flavour.

Incorrect Water Temperature

Another common oversight is using water that is too hot. If boiling water is poured into the cup, it can scorch the espresso, leaving a burnt or overly bitter flavour. Aim for water around 92–96°C—hot enough to extract the best from the espresso, but not so hot that it compromises taste.

Using Too Much or Too Little Water

Striking the right balance between espresso and water is essential. Adding too much water dilutes the coffee until it becomes weak and watery, while too little leaves it too strong, resembling a short black. A typical ratio is 60–120ml of hot water topped with a double espresso shot, but this can be adjusted slightly depending on your preference.

Neglecting the Cup

It might seem minor, but the cup you use plays a role. Preheating your cup with hot water before brewing helps maintain the coffee’s temperature and ensures the flavour profile remains consistent as you drink it. Skipping this step can cause the coffee to cool too quickly, muting the overall experience.

Overlooking Freshness and Timing

Coffee is best enjoyed fresh. Leaving your espresso shot sitting before combining it with hot water can cause the crema to dissipate and the flavour to degrade. Always prepare your water and espresso in sync, so they come together immediately.

Perfecting a long black is all about attention to detail

From choosing fresh beans to respecting the correct pouring order, small adjustments can make a big difference in taste. By avoiding these common mistakes, you’ll be able to brew a café-quality long black at home that highlights the depth and character of your coffee beans.
