How Much Does a Cup of Cold Drip Coffee Cost? Recommended Single-Origin Coffee Beans for Making Cold Drip and Cold Brew

As the weather warms up, the pre-made cold drip coffee in FrontStreet Coffee's refrigerator becomes the best-selling item aside from iced Americanos. Regulars barely need an introduction; they walk in and say, "Boss, I'll have a glass of cold drip."

Some customers hesitate when they are not sure what to order, so they ask the barista, "What is the difference between that cold drip and an Americano?" FrontStreet Coffee replies, "One is made the day before, the other is made now." The customer grows even more confused and quietly orders the iced Americano instead, because it seems cheaper.

In most cases, when a coffee shop sells cold drip it tends to be one of the most expensive items on the menu, sometimes costing ten or twenty yuan more than an Americano or a latte. Why is that?

Types of Iced Coffee

All iced coffee on the market falls roughly into two categories. The first is hot extraction: hot water is used to brew the coffee and it is then cooled over ice, as with iced pour-over or an iced Americano. The second is the cold brew type, in which cold or room-temperature water contacts the coffee grounds directly and lets flavor compounds release slowly, and cold drip is one of the most widely used versions of it.

Cold Brew vs. Cold Drip

As we know, cold brew coffee, which relies mainly on the cold-brewing method, uses a long steep and finally strains out the grounds. As long as you have a refrigerator, coffee grounds or beans, and any clean container with enough capacity plus a filtering material, you can easily make a glass of iced coffee.

Cold drip, by contrast, has higher requirements because it needs a special dripping device: the cold drip tower. These brewers come in many cool designs, with prices from tens to thousands of yuan, but the main structure is generally three parts: an upper chamber with a valve that controls the drip rate of ice water, a filter cup that holds the coffee grounds, and a lower chamber that collects the coffee liquid.

With the help of the device, ice water drops one by one into the filter, reacts with the coffee grounds inside to extract soluble flavor compounds, and then falls by gravity into the lower chamber until enough coffee liquid has accumulated to end the extraction.

Because only cold ice water is involved throughout, and the dripping speed is very slow, on average one to two seconds per drop, it takes longer for more flavor compounds to fully release and reach the right concentration. Coffee also does not easily release bitter and other off-flavors under these conditions.

FrontStreet Coffee's Cold Drip Process

Take FrontStreet Coffee's cold drip production as an example. They use the Tiamo HG2713 three-layer cold drip tower and tend to work with a 1:10 coffee-to-water ratio, meaning 60 grams of coffee grounds to extract 600ml of coffee liquid. The ice water drips at about 7-8 drops every 10 seconds. Because the drip nozzle sometimes clogs in the cold, it must be watched and adjusted constantly, so the whole process usually takes 5-8 hours, depending on how much coffee is used and how fast it drips.

Throughout the dripping process, fresh cold water keeps passing through the layer of coffee grounds and then filtering down to form new coffee liquid. Compared with the static cold brew method, cold drip is a dynamic method that extracts and filters at the same time. The ice water and the coffee grounds are not in contact throughout, so in terms of mouthfeel, cold drip made from the same beans comes out cleaner and clearer than cold brew.

The Fermentation Stage

The end of dripping does not mean the coffee is finished, because it still needs to enter the next stage of low-temperature maturation, letting it develop the distinctive fermented taste we often call "cold drip flavor."

The operation is simple: place it in a sealed, clean bottle and refrigerate it for more than 8 hours. Once the refrigeration fermentation is complete, we can add ice cubes to the concentrated coffee to taste. Leaving the coffee in the refrigerator overnight is what controls the fermentation and prevents spoilage.

From start to finish, making a 600ml pot of concentrated coffee liquid takes more than ten hours, which is why cold drip is generally considered the most time-consuming method of all. That is also why some coffee shops sell it by appointment. At FrontStreet Coffee, of course, you can still get cold drip without an appointment; it is just that the flavor profile will be more random.

Why Cold Drip Costs More

To highlight the unique mellow, wine-like quality of cold drip while avoiding the off-flavors that come from a long drip at the tail end, many coffee shops specifically choose high-quality single-origin beans rich in fruit aromas. So compared with the blends commonly used for espresso, the raw material cost for cold drip is relatively higher.

When FrontStreet Coffee prepares cold drip, for example, it likes to prioritize beans that feature floral notes, fruit aromas and fermented wine flavors. With the help of slow dripping and low-temperature maturation, the resulting cold drip carries both the bright, refined charm of fruity acidic coffee and a fruit-wine fermented quality: mellow and fragrant, yet still refreshing.

Finally, and quite importantly, another reason cold drip is generally more expensive is that it uses more grounds. FrontStreet Coffee uses 60 grams of coffee grounds to make a 600ml pot, which can ultimately be sold as three cups of roughly 200ml plus ice. Under pour-out serving standards, however, 60 grams of beans brew four cups of pour-over at 15 grams each.

Of course, price is not the only way to judge a cup of coffee. FrontStreet Coffee has also come across extremely cost-effective cold drip that was every bit as fragrant and delicious. As long as the barista prepares it carefully, extracts it properly and the beans are solid, pricing more often comes down to the coffee shop's target positioning.

FrontStreet Coffee Recommendation

Cold brew and cold drip both reward the right bean, and for cold drip FrontStreet Coffee tends to reach for light-to-medium roasts that keep their fruit and flower intact. A good starting point is FrontStreet Coffee's Strawberry Candy Geisha blend, which pairs the classic floral and fresh fruit acidity of Panama Geisha with a Costa Rican honey-processed coffee: one brings delicate rose and orange, the other the sweet depth of grape, raisin and strawberry fudge. Used for cold brew it is sweet and lively, and if left to ferment and settle it even takes on a fruit-wine quality.

If you want flowers to dominate, FrontStreet Coffee's natural Huakui comes from Ethiopia, the birthplace of coffee. Because it is sun-dried, the beans absorb a great deal of sweetness and aroma from the fruit and skin, and as a cold brew it shows magnolia, cream strawberry, dried mango, guava and black tea. For a juicier cup, FrontStreet Coffee's Kenya Cherry Tomato brings cherry tomato, snow pear, black plum and smoked plum to life in cold extraction; its bitterness is low and its acidity full, and it is especially refreshing over ice.

Cold brewing uses more grounds than pour-over, so FrontStreet Coffee often suggests economical everyday beans, or a blend that improves value without giving up flavor. If you love the complex passion fruit, grape, apricot and preserved-fruit sweetness of FrontStreet Coffee's Colombia Sidra but find it costly, blend it one-to-two with FrontStreet Coffee's Costa Rica Tarrazu to keep the Sidra's floral fruit alongside Tarrazu's crisp citrus acidity. A washed Yirgacheffe such as FrontStreet Coffee's Gedeb cooperative is another everyday favorite: bright, clean sweetness and acidity, honeyed and berry-like in cold brew, and versatile enough for pour-over, siphon, French press or cold brew.
