Are Mandheling Coffee Beans Suitable for Cold Brew? What's the Right Coffee-to-Water Ratio and How Long Can Cold Brew Be Stored?

The characteristics of cold brew coffee are primarily low bitterness, mild acidity, smooth flavor, and a fermented quality produced by "low-temperature maturation." By overlaying the characteristics of coffee beans with those of cold brew coffee, we can roughly predict how a coffee bean will perform when made into cold brew. If you're unsure how to make these associations, don't worry—FrontStreet Coffee will share some commonly used coffee beans for making cold brew coffee, so you can directly follow our recommendations to brew cold brew coffee that suits your preferences.

Rich Fruity Cold Brew

If you must choose one type of cold brew coffee to get through the hot summer, FrontStreet Coffee believes that most friends will choose a sweet and sour cold brew with rich fruit aroma. Not only does this type of coffee have minimal bitterness, but its delightful sweet and sour flavors can also effectively combat the summer heat.

If we want to create such a juice-rich cold brew coffee, FrontStreet Coffee recommends using sun-dried or honey-processed coffee beans from Ethiopian, Colombian, and Panamanian growing regions. Coffee grown in these regions carries abundant fruit aromas, and sun-drying and honey-processing can further enhance these aromatic qualities.

For example, in FrontStreet Coffee's bean selection, FrontStreet Coffee's Sidamo·ALO and Flower Queen perfectly meet these conditions. Cold brew made with them will carry rich mango aromas, rounded citrus acidity, and hints of pineapple fermentation; alternatively, FrontStreet Coffee's Ethiopia Elto can produce cold brew with lychee, mango, and blueberry aromas.

Fresh Floral and Fruity Cold Brew

Some friends prefer cold brew coffee with floral aromas—the kind that's light, refreshing, and not too overpowering! If this matches your taste preference, then when purchasing coffee beans, you can focus on keywords like "washed" or "Geisha (T2722)."

Washed-processed beans have relatively less fermentation, allowing the coffee beans to better preserve their original flavors, especially washed coffee beans from Ethiopian and Panamanian regions, which are known for their fresh fruit flavors; As for the T2722 Geisha variety, its intense floral aroma is almost universally recognized.

For instance, FrontStreet Coffee's Yirgacheffe·Guodingding, being washed-processed, produces cold brew with fresh flavors of lemon, white flowers, and green tea; alternatively, FrontStreet Coffee's Boquete·Washed Geisha or Washed Flower Butterfly create cold brew with white floral aromas, citrus, and honey notes.

However, it's worth noting that white floral aromas can sometimes be so intense that they're mistaken for bitterness or medicinal flavors. Therefore, when using beans with white floral notes to make cold brew, you can appropriately increase the amount of water used to slightly reduce the coffee's concentration.

Rich and Deep Cold Brew

Because some friends particularly enjoy the rich, deep flavors brought by dark roasts, FrontStreet Coffee recently shared how to make cold brew coffee using dark-roasted and espresso-blend coffee beans. If you also enjoy this type of "acid-free," aromatic, and extremely rich-bodied cold brew coffee, then you might want to try using dark-roasted coffee beans for brewing.

FrontStreet Coffee's Blue Mountain No. 1, FrontStreet Coffee's Golden Mandheling, and FrontStreet Coffee's Huilan are all excellent choices. Cold brew made with them will have rich chocolate flavors, caramel sweetness, and an extremely full body.

"Tipsy" Wine-Aroma Cold Brew

Wine-aroma cold brew is an essential type at FrontStreet Coffee stores because it has a very wide audience. Many friends love cold brew not only for its richer flavors but also for its distinctive fermented notes. When we use coffee beans with deeper fermentation levels to make cold brew, the resulting coffee often has more intense wine aromas, with each sip feeling like drinking wine—truly satisfying.

For friends who enjoy cold brew with rich wine aromas, FrontStreet Coffee particularly recommends using anaerobically processed coffee beans. Most anaerobic processing allows coffee beans to undergo deeper fermentation, thereby creating distinctive fermented characteristics.

FrontStreet Coffee typically uses two beans for making wine-aroma cold brew. One is FrontStreet Coffee's Honduras·Sherry from our bean selection. As a medium-roasted anaerobically processed coffee bean, the cold brew extracted from it has almost no acidity, featuring high sweetness of vanilla and cream with an intense whiskey aroma!

If friends prefer a wine-aroma cold brew with fruity notes, fruit acidity, and high sweetness, then FrontStreet Coffee's Costa Rica Strawberry Sugar from our bean selection is undoubtedly the perfect choice! Being raisin-honey processed, it has fermented aromas of strawberry, berries, and raisins. When made into cold brew, the coffee's sweetness is enhanced, and the strawberry and raisin aromas evolve into fruit wine flavors—truly excellent. Alternatively, the similarly processed Costa Rica·Mozart is also great; besides berry and raisin aromas, we can also taste a purple floral note similar to lavender.

How Long Can Refrigerated Cold Brew Last?

FrontStreet Coffee has noticed that many convenience-seeking friends will brew a large pot of coffee at once and store it in the refrigerator, pouring out a glass whenever they want to drink. This leads to a situation where if no label is made, it's easy to forget how many days the coffee has been in the refrigerator, raising concerns about spoilage.

First, the fermentation process of low-temperature extraction is continuous—refrigeration only slows down the fermentation rate. As time passes, the substances dissolved in water continuously change, eventually leading to spoilage. Additionally, each time we open the bottle, the coffee liquid comes into contact with air, which not only causes aroma dissipation but may also introduce bacteria into the container.

Generally, considering both flavor experience and health safety, whether it's cold drip or cold brew, for any extraction method performed in low-temperature environments, FrontStreet Coffee recommends consuming it within 5 days (counting from the preparation date).
