Background
The goal of this experiment is to evaluate a light, acidic beverage brewed from spent coffee grounds. The extraction yields a profile that is less harsh than fresh coffee, tasting similar to a diluted, acidic cold brew but highlighting the warmer, gentler notes of the bean.
This profile suggests several potential pairing and development paths, particularly combining the spent coffee with fruit, blackened ingredients, or citrus and syrup bases.
Recipe
Ingredients
- 920g water
- 80g honey
- 50g spent coffee grounds
Notes and Observations
- Sensory Profile: The resulting liquid is highly pleasant. Much of the typical harshness of coffee has subsided. It drinks like a diluted, acidic cold brew, emphasizing the warmer, softer notes of the coffee.
- Pairing Ideas:
- This would pair exceptionally well with fruit, blending bright fruitiness with the warm coffee notes. It recalls the flavor profile of cascara (mashed coffee cherries) or certain blackened ingredients, which tend to develop deep, cherry-like fruitiness.
- A combination of spent coffee grounds and a blackened grain could yield a very interesting, complex beverage.
- It would also pair well with citrus.
- Another direction to explore is using sorghum syrup or a burnt sugar syrup as a base. This could mimic the classic espresso, seltzer, and orange juice combination—creating a carbonated beverage with tropical notes from the sorghum syrup and a deep undertone from the spent coffee.
