As the weather gradually warms up, many people like to keep a jug of icy, smooth cold brew coffee in the fridge. In fact, the key to brewing a jug of refreshing cold brew lies in choosing the right coffee bean origin and terroir. This is because long, low-temperature steeping amplifies the coffee bean's own fruit acidity and aroma while reducing the bitterness brought by dark roasting. Choosing along the terroir map often helps you find your own exclusive flavor with half the effort.

If you want a bright aroma like floral and fruity tea, African origins will surely surprise you. For example, the Front Street sun-dried Huakui coffee from Ethiopia, the birthplace of coffee, has green beans that absorb rich sugars from the fruit skin and pulp during the sun-drying process. When used for cold brew, the originally restrained floral and fruity notes are completely awakened, and you can clearly taste the rich sweetness of magnolia, cream strawberry and dried mango, with an elegant black tea aroma in the finish.

If you crave a more abundant juicy feel, the Front Street Kenya Cherry Tomato coffee from the Thika region of Kenya is very suitable. It is bred from the excellent SL28 and SL34 varieties, combined with the local unique K72 double washed processing method, and the medium-light roast retains extremely lively acidity. After making cold brew, the bitterness is very low, and the full sweet-tartness of cherry tomatoes, snow pear and black plum bursts on the tongue, and it is even more refreshing and pleasant after chilling.

If you prefer a lighter and more transparent mouthfeel, the washed Front Street Yirgacheffe Gudingding Cooperative coffee is especially worth keeping on hand. As an enduring everyday choice, it shows an especially refreshing and bright citrus acidity and honey sweetness under low-temperature slow extraction. The whole cup tastes layered and distinct, with the slight tartness of berries interwoven with gentle floral notes, just like a freshly brewed berry iced tea, easy to drink and comforting.

Leaving Africa and coming to Central and South America, the terroir here is better at creating a sweet and balanced tone. The Front Street Strawberry Candy Geisha blend coffee cleverly combines Panama Geisha with Costa Rica honey-processed beans. Panama brings delicate rose and orange aromas, while Costa Rica adds the rich sweetness of grapes and strawberry gummy candy. After cold brew production, it is not only lively in sweetness and acidity, but after proper refrigeration and slight fermentation it even carries a fascinating fruity wine aroma.

Making cold brew generally uses a relatively large amount of grounds, and high-quality beans from Central and South America can also balance budget and taste through creative blending. For example, many people love the full passion fruit and apricot sweetness of Front Street Colombia Sidra coffee, so you might add Front Street Costa Rica Tarrazu coffee at a 1:2 ratio. This preserves Sidra's bold dried fruit aroma while blending in Tarrazu's clean citrus tone, making everyday large-jug steeping especially cost-effective.

Before formally putting newly bought beans into the cold brew jug, it is worth first calibrating the flavor with a regular pour-over. Grind 15 g of coffee grounds and prepare 225 ml of hot water at a 1:15 coffee-to-water ratio. First pour in 30 ml of water and evenly bloom for 30 seconds, then use a steady staged pour, keeping the total brewing time at around 2 minutes. Through the aroma and sweetness of this hot cup of coffee, you can quickly judge its flavor direction in cold brew.

For friends who prefer a rich and mellow texture, the terroir characteristics of Asian origins should not be ignored either. Beans such as Indonesian Mandheling or those from Yunnan, China, have solid nutty, herbal and chocolate notes. During cold brew steeping, this type of terroir gives the coffee a thicker, smoother body and a deeper sweetness, and adding ice cubes or directly mixing in fresh milk turns it into a rich and delicious iced latte.

The world of coffee is vast and broad, and every time you open beans from a different origin, it is like starting a taste exploration across mountains and seas. Whether you are fond of Africa's bright floral and fruity notes, Central and South America's balanced sweetness, or Asia's gentle mellowness, as long as you choose according to the terroir traits you prefer, that jug of cold brew left overnight in the fridge will make every sip a perfectly gentle enjoyment.
