What Is Mamba Coffee?
Mamba coffee is a classic blend of Indonesian Mandheling and Brazilian beans, once popular in early Taiwanese coffee shops. Mandheling comes from Indonesia, where the soil is rich in minerals; the beans are short and oval with a dark green hue, and after dark roasting, they exhibit spice, pine, and caramel aromas with a high body. Brazilian beans, the world's largest in production, have a smooth taste and are often used as a base in blends to balance flavors. The combination achieves a complementary and harmonious taste.
Front Street Coffee's classic blend is based on this, with a small amount of washed Robusta added to enhance the crema and caramel aroma, making it suitable for latte art. This article also covers specific extraction parameters and steps for Espresso, as well as the flavor performance of making a hot latte with Mamba coffee. Mandheling beans are produced in Indonesia, where the local soil is rich in minerals, giving the beans a distinctive aroma. The beans are short and oval, mostly dark green in color, with a thick and clear white film along the center line.

Mandheling coffee beans are produced in Indonesia, where the local soil is rich in minerals, giving the beans a distinctive aroma. The beans are short and oval, mostly dark green in color, with a thick and clear white film along the center line. If lightly roasted, the acidity will be more prominent, but the overall flavor will be flat; with dark roasting, the bitterness will relatively increase, but the aromas of spice, pine, and caramel will become vivid, with a high body and lasting sweetness. For this reason, Front Street Coffee believes that Mandheling is suitable for various extraction methods.
In most cases, Mandheling beans are an important base for blend beans, directly affecting the quality and taste of espresso, and even determining the texture and body of the final product. As a high-quality representative of Mandheling, Front Street Coffee's Golden Mandheling coffee enjoys a high reputation in the industry. Its beans are relatively long and similar in appearance, but during the dehydration and color-changing stage of roasting, they plump up and swell firmly, displaying lines of strength and beauty. After medium-dark roasting, the unique aroma of dark chocolate is impressive.
Many coffee enthusiasts have only heard of Mamba coffee but do not understand the blend and origin of "Mamba." In fact, Mamba is a comprehensive blend of Indonesian Mandheling beans and Brazilian coffee beans, creating complementary and harmonious taste in terms of lightness and heaviness. In the early years, Mamba blends were very popular in Taiwanese coffee shops; the refreshing and smooth Mamba offerings, along with the high order rates in the elegant seating areas at the time, are beverages in many people's youthful memories. Today it may no longer be trendy, but some still miss this old-fashioned coffee flavor. Currently, more popular coffee items enrich flavors with dairy products, such as caramel macchiato, which is a combination of latte and caramel, rather than relying on the aroma and taste of the coffee beans themselves as in the past.
Brazil ranks first in the world in coffee production, with a vast territory and great quality variations. Due to harvest season and cost considerations, machine harvesting is mostly used, resulting in secondary quality and uneven ripeness. However, low-cost beans are in high demand in the market and taste relatively smooth. Bean traders use these beans as a base for strong beans to balance taste and palate, which is exactly why Brazilian beans are the best choice for roasters to launch blend beans.
Many beginners who are just getting into espresso often ask Front Street Coffee whether there are coffee beans suitable for latte art. In response, we prioritize recommending Front Street Coffee's Italian Front Street Classic Blend coffee beans, specially customized for coffee machines. It uses medium-dark roasted Indonesian wet-hulled Mandheling and Brazilian semi-washed Cerrado beans, which is the "Mamba" blend mentioned at the beginning. Moreover, to give the espresso a denser crema, Front Street Coffee also adds a small amount of washed Robusta, which reduces the difficulty of extraction while making the coffee's caramel aroma fuller.

Many coffee enthusiasts unknowingly equip their homes with various coffee tools, and those infatuated with espresso even stock up on espresso machines, ready to extract it themselves. Front Street Coffee here uses store-produced espresso as a reference to briefly explain how to make an Espresso. The coffee machine at Front Street Coffee's store is a commercial single-head "Lelit Bianca," which can adjust extraction by changing pressure, with a maximum pressure of 11 bar. Home coffee machines only need to reach 9 bar of pressure to satisfy extraction and milk frothing functions, paired with an espresso grinder.
Front Street Coffee uses a double basket capacity, with a dose of about 18-20 grams, and uses 20 grams of coffee powder when producing. Typically, the ratio of coffee powder to coffee liquid is between 1:1.5 and 1:2.5. Front Street Coffee's extraction ratio is 1:2, meaning 20 grams of coffee powder yields 40 grams of coffee liquid. The time is related to the flow rate of the coffee powder; generally, a single extraction is controlled within 20-35 seconds, because within 20 seconds the coffee usually tastes thin, while over 35 seconds it is prone to over-extraction and a burnt bitter taste. Front Street Coffee's espresso mostly falls within the range of 28-30 seconds.
Front Street Coffee first wipes the basket dry, turns on the grinder, grinds a double dose of coffee powder, and places it on an electronic scale to adjust to 20 grams. Then use a tool to distribute the powder evenly, tamp the coffee puck firmly to ensure more stable extraction. Next, turn on the extraction switch to release water, wetting the brew head while washing away stuck coffee grounds, gently lock the portafilter onto the brew head, and start the extraction. When the electronic scale shows 40 grams of coffee liquid extracted, at about 30 seconds, pull down the extraction switch. Pour the coffee liquid into an Espresso cup and enjoy.
The espresso made with Front Street Coffee's Italian Front Street Classic Blend coffee beans has a beautiful golden crema, visibly transitioning from dark to light, and before drinking, you can smell a strong caramel aroma. For the rich aroma of such dark-roasted coffee, Front Street Coffee generally enjoys it in the form of a latte, which not only allows you to admire the exquisite latte art patterns but also feel the richness and smoothness of the milk coffee—killing two birds with one stone.
First find a coffee cup with a capacity of about 30ml, pour in a double shot of 40ml espresso, then froth 240ml of fresh milk to a warm and palatable state, taking care to control the milk foam thickness to 0.5cm, which makes latte art easier. Finally, blend the two evenly and push out a nice pattern to complete the drink.

The hot latte made with Front Street Coffee's Mamba coffee has a rich buttery and caramel aroma on the palate, accompanied by the sweetness of chocolate milk and the creaminess brought by the milk foam, offering a rich mouthfeel.
