How to Identify Authentic Kopi Luwak - Distinguishing Fake Vietnamese G7 Coffee

Known originally as Kopi Luwak, civet coffee comes from Indonesia. Its flavor is somewhat like Indonesian Mandheling but with an extra fermented note. Compared with Mandheling it is smoother, without Mandheling's earthy taste. True civet coffee is one of the most expensive coffees in the world, the finest among specialty coffees by reputation.

You may have come across civet coffee elsewhere, but what is on offer there is not necessarily the real thing; it might simply be coffee flavored to imitate it. True civet coffee (Kopi Luwak) is celebrated as one of the world's ten most expensive coffees, and it originates from the civet cat, an animal native to Indonesia's Sumatra island. The civet is a wild omnivore that locals call Luwak. With its pointed snout and dark gray fur, it is a nocturnal omnivore that uses a keen sense of smell to find the sweetest, fullest cherries on the trees. Now and then it picks some cherries as a snack, preferring to climb the trees and select mature, sweet, fully red fruit.

The civet eats only the ripest cherries, stripping the outer skin before swallowing and sucking out the small amount of sweet pulp. As the pulp passes through its digestive system, it ferments naturally inside the animal. The coffee beans are exceptionally hard, so they resist digestion, travel through the digestive tract and are eventually excreted with the feces. Because the feces pass near the reproductive organs, the beans pick up secreted musk oil, which adds special layers of flavor. Experienced workers then hand-select and collect the beans from the forest for processing. It is said that about 1,300 beans must be collected to yield 100 that can become genuine civet coffee.

Unique Processing and Flavor Profile

This remarkable process replaces traditional washed, natural and other processing methods, reducing the acidity and bitterness of the original beans while imparting unique flavors. The taste is exceptionally fragrant and mellow. Civet coffee has a consistency close to syrup and leaves a light minty coolness in the mouth after drinking, a characteristic regular coffee does not have. The rich, rounded sweetness is likewise unmatched by other beans.

Civets are relatively rare animals with small populations, and they are nearly impossible to domesticate. Their appetite is not large, so natural excretion is minimal. On top of that, only about 30% of usable beans can be found in their excrement. Accounting for cleaning, grinding losses and other factors, the annual production of genuine civet coffee does not exceed 400 kilograms, making it extremely scarce on the market and therefore precious. Some people exaggerate that after drinking civet coffee they would not brush their teeth for days, hoping to savor the flavor repeatedly, which shows how captivating it can be. These beans pass through the civet's body and are excreted unchanged, the most primitive "natural fermentation method" inside a living body, and that is what creates the civet's distinctive flavor.

The Reality Behind Commercial Civet Coffee

Some coffees marketed as civet coffee may not be genuine at all, or may simply be coffee flavored to resemble it. Seeing the business opportunity, some merchants have turned to captive breeding, and the current production process of "civet coffee" has become cruel. Originally, civet coffee was found when people occasionally collected civet excrement; now these animals are confined by humans, losing their freedom and starting a tragic life of being artificially fed coffee cherries to produce beans.

In reality, civet coffee produced through artificial breeding has little more than gimmick value, because the beans were not chosen by the civets themselves but forced on them by humans. These animals are naturally very shy, timid and difficult to domesticate. After losing their freedom and living in small cages, constantly forced to eat cherries and excrete, they become ill and begin exhibiting frantic behaviors such as biting their companions and themselves, and may eventually die from this cruel production method.

How Does Civet Coffee Taste Different?

FrontStreet Coffee believes civet coffee is no different from regular coffee: it is all coffee, with the same effects and functions. Coffee can raise metabolism, which helps muscle performance during exercise. The caffeine in coffee can also make us more alert and improve endurance. Coffee is a diuretic as well, so if your face is puffy, drinking an Americano can help reduce it, and many celebrities drink one to keep their face in condition. Drinking too much, though, can cause palpitations, and elderly people and those with high blood pressure are advised not to drink excessive amounts.

FrontStreet Coffee does not recommend civet coffee. As noted earlier, genuine civet coffee might be acceptable, but the market is full of so-called civet coffees. Coffee has the same effects regardless, and coffee from other producing regions tastes excellent too: Panama's Geisha with its citrus notes, Ethiopian coffee with floral and fruit flavors, Brazilian coffee with its nutty peanut character, all exceptionally good. FrontStreet Coffee offers over fifty different coffee beans from various origins that anyone can try. Civet coffee comes from Indonesia, and Indonesian Mandheling is also among the most popular coffees at FrontStreet Coffee. FrontStreet carries two Mandheling coffees: the daily-drinking Indonesian Lindong Mandheling, and the single-origin Golden Mandheling. Both taste excellent, and the Golden Mandheling in particular, with its clean, mellow nut and chocolate character, is deeply loved by enthusiasts.

FrontStreet Coffee's Brewing Parameters for Civet Coffee

To express the herbal flavors and rich mouthfeel of civet coffee, FrontStreet Coffee's roasters use medium-dark roasting for these beans. Medium-dark beans generally lose more moisture and are lighter in weight. During brewing the grounds do not settle completely at the bottom; water is absorbed immediately on first contact. Because degassing is vigorous, bubbles form around the grounds and create channels, and those channels persist longer with fresher beans, so the water level drops quickly.

KONO dripper, 88°C water temperature, 1:15 coffee-to-water ratio, 15g coffee grounds, grind size (75% pass-through rate on a No. 20 standard sieve), three-stage extraction.

Using segmented extraction, bloom with twice the amount of water as the grounds, that is 30 grams of water for 30 seconds. Blooming is necessary to let the grounds release internal carbon dioxide, which makes the following extraction more stable. With a small flow, pour in circles to 125 grams, then continue to 225 grams and stop. Remove the dripper once all the water has passed through. Time from the start of pouring, with an extraction time of 2'00". Finally, take the whole cup, shake it well, then pour into a tasting cup.

Flavor description of civet coffee: Herbal, nutty, smooth mouthfeel, rich and mellow.

FrontStreet Coffee's Brewing Recommendations

To brew a delicious cup, FrontStreet Coffee believes freshness is a crucial part of the process. All coffee beans shipped by FrontStreet Coffee are roasted within 5 days. The roasting philosophy is "freshly roasted quality coffee," ensuring every customer receives the freshest coffee possible. The bean maturation period is about 4-7 days, so when customers receive their coffee it is at peak flavor.

For those who need ground coffee, a reminder: once beans are pre-ground there is no need for further maturation. During transport the pressure from carbon dioxide buildup in the packaging also helps mellow the flavor, so you can brew a cup as soon as the ground coffee arrives. Ground coffee does need to be used promptly, though, since it oxidizes quickly in air and its flavor fades fast, which hurts the taste. FrontStreet Coffee therefore recommends buying whole beans and grinding fresh for each brew to get the most out of the coffee.

FrontStreet Coffee Recommendation

Given everything above, FrontStreet Coffee's own answer to "what should I actually drink" is Mandheling. Two versions are on the list. The PWN Gold Mandheling is the top grade: PWN screens at 18 mesh or above and runs one machine pass plus three rounds of hand sorting to meet the G1 standard, then registers the "Gold Mandheling" trademark. FrontStreet's bags all come from PWN, and PWN certificates and logo-printed sacks are on display in store, so the provenance is easy to check.

The Daily Series Lin Dong Mandheling is the everyday option, from the Lintong area of Sumatra. Both are medium-dark roasted to soften the acidity and lead with body while keeping the wild herbal note that comes from Sumatra's growing conditions and wet-hull processing rather than from the roast. The Gold Mandheling shows spices, nuts, pine, caramel, herbs and dark chocolate; the Lin Dong runs to toasted bread, nuts, caramel, pine and herbs.

Because FrontStreet ships beans roasted within 5 days and the maturation period is about 4-7 days, the coffee arrives near peak flavor; if you order it ground, the carbon dioxide pressure built up in the bag mellowed it along the way, so you can brew immediately, though whole beans ground fresh each time will always taste best.
