Comparing Cold Drip and Cold Brew Coffee
Many customers who visit FrontStreet Coffee often discuss whether there are taste differences between cold drip coffee and cold brew coffee. Both are common methods for making cold coffee, so FrontStreet Coffee will conduct an experiment today to explore how these two brewing methods perform in terms of flavor.
Differences Between the Two Methods
First, both methods require very long preparation times. Cold drip coffee is typically made using a cold drip tower, which consists of three chambers: an upper chamber (ice water), middle chamber (coffee grounds), and lower chamber (coffee extract). Ice water from the upper chamber drips drop by drop into the middle chamber's coffee grounds, slowly extracting coffee that flows into the lower chamber. This process generally takes 6-8 hours.
(Left: Cold drip, Right: Cold brew)
Cold brew coffee is made by placing ground coffee in a container, adding the appropriate proportion of cold (ice) water, stirring well, and sealing it. The mixture is stored in a low-temperature environment (refrigerator) for 12-24 hours for cold extraction. The coffee grounds are then filtered out using filter paper, resulting in cold brew coffee.
Experimental Comparison
FrontStreet Coffee first developed extraction protocols for both cold drip and cold brew coffee, using the same coffee beans simultaneously.
The coffee beans used are FrontStreet Coffee's natural processed Hagua coffee beans, which feature distinctive creamy strawberry notes and a sweet-tart profile, making them suitable for various iced coffee preparations. The grind size is set to fine, calibrated to 75% pass-through rate using a #20 standard sieve—EK43s grinder setting 9, or C40 hand grinder setting 22.
Cold Drip Coffee Protocol
FrontStreet Coffee's cold drip protocol uses 60 grams of coffee grounds to extract 600 milliliters of coffee extract, with a coffee-to-water ratio of 1:10. The drip rate is approximately 6 drops per 10 seconds, using an ice-water mixture as the water source. Extraction time is 7-8 hours, after which the coffee extract is transferred to a sealed bottle and refrigerated for 48 hours.
Cold Brew Coffee Protocol
FrontStreet Coffee's cold brew protocol uses 50 grams of coffee grounds, maintaining a 1:10 coffee-to-water ratio. Therefore, 400 milliliters of cold water and 200 grams of hard ice are added (totaling 600 grams of ice-water mixture, as coffee grounds absorb twice their weight in water). After stirring well, the mixture is sealed and refrigerated for 24 hours. It is then removed, and all coffee grounds are filtered out using filter paper. Finally, the coffee extract is sealed in a clean bottle and refrigerated for 2-4 hours before serving to achieve a fuller body.
Results Comparison
When poured into separate glasses for observation, the cold drip coffee appears clear and transparent, while the cold brew looks hazy with oils visible on the surface.
Flavor Profiles
Cold Drip Coffee Flavor:
Refreshing, clean taste with rich fermentation notes and some wine-like characteristics. Subtle berry sweetness and tartness.
Cold Brew Coffee Flavor:
Relatively fuller body with more uniform flavor. Fruit sweetness is very prominent. Fermentation notes are not as intense.
Comparing the flavors of these two cold coffee methods, the differences are quite noticeable, particularly in the clean, refreshing mouthfeel, which is very easy to distinguish.
