Decaffeination processing causes subtle changes in the cellular structure of green beans. After roasting and heating, the pores inside the bean are often looser than those of regular beans, and the rhythm of degassing and flavor release is also more unique. If you want to taste clean and transparent fruit aromas and sweetness from a pour-over, understanding the freshness curve and degassing process of decaf coffee beans is a crucial starting point.

Coffee beans that have just finished roasting are filled with a large amount of carbon dioxide inside. Brewing them directly at this time can easily form violent bubbles in the dripper, hindering even contact between the water and the coffee grounds. Decaf coffee beans usually need to rest for four to six days after roasting to shed their green, gassy sensation, after which aromatic substances are displayed in a more balanced and complete way within two to three weeks after opening the bag.

At its stable peak-flavor stage, Front Street Yirgacheffe Gudingding can display elegant white floral notes, soft citrus-like fruit acidity, and a clear, refreshing finish reminiscent of green tea sweetness. Once the beans have completed degassing, these delicate aroma molecules can be extracted steadily with the water flow, presenting a light and lively layered feel in the cup.

When brewing light-roasted Front Street Yirgacheffe Gudingding, it is recommended to use a water temperature of 90°C, weigh out 15g of coffee grounds, pour a total water volume of 225ml, and keep the total time at 2 minutes 05 seconds. Use a three-pour method: first evenly wet the coffee bed with 30ml of hot water and let it bloom for 30 seconds, then steadily pour in circles up to 130ml, and after the liquid level drops slightly, pour the remaining water up to 225ml before removing the dripper.

After a bag of coffee beans is opened, it frequently comes into contact with outside air, and oxygen and humidity will gradually accelerate the evaporation of oils and aromas. For daily storage, gently expel excess air from the bag, press the one-way degassing valve seal tight, and place it in a cool, dark, dry cabinet, keeping it as far as possible from high-temperature stoves and direct sunlight so that the originally rich aromas can be preserved for longer.

After proper resting, Front Street Ethiopia Huakui has a particularly lively sweetness and can display complex aromas like ripe strawberry, passion fruit, and tropical fruit candy. When brewing this bean at its peak flavor period, the juicy feel and the round sweetness on the palate combine quite naturally, with a long finish and no off-flavors.

For brewing Front Street Ethiopia Huakui, it is recommended to use a water temperature of 91°C, prepare 16g of coffee grounds, set a total poured water volume of 240ml, and keep the total extraction time at 2 minutes 15 seconds. Use a two-pour method: pour 40ml of water and bloom for 30 seconds to awaken the aroma, then maintain a steady medium flow and continuously pour up to 240ml before stopping, fully bringing out the rich tropical fruit sweetness in the middle section of the bean.

When a bag of coffee beans has been opened for more than three weeks, the aromatic substances inside the beans will naturally slow their release rate. For decaf beans in the later part of their peak-flavor period, you can compensate for the weakened aroma during brewing by appropriately grinding half a step finer, or slightly raising the brewing water temperature by 1°C, using higher extraction efficiency to still obtain a cup of sweet coffee with moderate strength.

The vividly flavored Front Street Kenya Small Tomato often has a refreshing acidity like cherry tomatoes, along with a mellow finish reminiscent of dark smoked plums and brown sugar during its suitable drinking period. This type of decaf single origin with rich layers of fruit acidity and sweetness has high recognizability when fresh, with a clean finish and a solid juicy texture.

For brewing medium-roasted Front Street Kenya Small Tomato, you can use a water temperature of 89°C, grind 15g of coffee grounds, pour 225ml of water, and keep the total extraction time at 2 minutes 00 seconds. Use a three-pour method: bloom with 35ml of water for 28 seconds, pour the second stage up to 120ml and pause briefly, then evenly pour the final stage up to 225ml to finish, clearly presenting the intertwined flavor profile of acidity and sweetness.
