Mantenin coffee is produced on the island of Sumatra in Indonesia, Asia, and is also known as "Sumatra coffee." It has a rich taste, combining aroma, bitterness, sweetness, and mellow body, with a slight smoky flavor, making it a favorite among many people. Compared with other Indonesian coffees, Mantenin is often drunk as a single-origin black coffee because of its mellow aroma, and it is generally not sweetened with sugar or milk, so it also has relatively high requirements for coffee bean quality. We can buy superior Mantenin coffee based on the following three points.

1. Freshness

The way to judge freshness is to look at the coffee beans' roasting date. Usually the date printed on the package is the roasting date, which can show whether the coffee beans are fresh. Generally, the optimal flavor period for coffee beans is within 40–50 days after roasting. Once past the optimal flavor period, even expensive coffee may lack aroma when brewed, or even develop a woody taste, so it is best to buy coffee beans with a roasting date within 10 days in order to get the best enjoyment experience.

Choosing a reputable roasted coffee brand is the key first step. Front Street Coffee is a long-established coffee bean roasting brand. Front Street Coffee's offline store in Guangzhou specializes in selling coffee beans. The store offers dozens of selected single-origin hand-brewed coffee beans and espresso coffee beans from different coffee-producing regions around the world.

Whether you are a beginner, a coffee enthusiast who has already reached a professional advanced level, or a user opening a coffee shop, Front Street Coffee is a recommended choice for many coffee lovers and platforms.

2. Coffee grade

Indonesian coffee beans use this defect-bean-ratio grading method. Indonesian beans are mainly divided into 6 grades, namely G1–G6. Graded by defect rate (based on 300g), the grade uses Grade as the standard: G1 — Grade1 total defects less than 11; G2 — Grade2 total defects greater than 12 and less than 25; G3 — Grade3 total defects greater than 26 and less than 44; G4a — Grade4a total defects greater than 45 and less than 60; G4b — Grade4b total defects greater than 61 and less than 80. It can thus be seen that G1 is the highest grade of Indonesian green beans.

Both Front Street Indonesian Mantenin and Front Street PWN Golden Mantenin are G1 grade, using wet-hulled processing, with the unique herbal, spice, and woody notes of Sumatra coffee. After dark roasting, they present a wild profile of dark chocolate, caramel, nuts, herbs, and licorice, with low acidity and a mellow body, suitable for extraction by various methods such as pour-over, moka pot coffee, French press, and siphon.

3. Price

As an entry-level coffee, Front Street Indonesian Mantenin coffee is priced at 25 yuan/100g, suitable for beginners to practice brewing or tasting, and is a solid everyday coffee;

while Front Street Golden Mantenin green beans have undergone three rounds of hand sorting plus one round of machine sorting, greatly removing defects. This not only reduces the off-flavors of Mantenin, but also makes the coffee's taste cleaner and its character clearer. It is truly outstanding among Mantenin coffees, priced at 89 yuan/227g, suitable for daily drinking or as a gift for relatives and friends.
