Could a cold brew be herbal, floral and fruit-sweet in the same glass? Castillo Aromatic coffee beans are described with aromatic lemongrass brightness, delicate florals and lychee sweetness. For a starting point on steeping and serving, use our cold brew guide and keep your first batch simple.

These are the coffee’s stated tasting notes, not a guarantee that every batch will show them equally. Extraction and serving conditions shift the balance, so begin with a consistent grind, water amount and steep. Then adjust one variable at a time to identify whether the herbal lift, floral aroma or fruit sweetness is coming through clearly.

What flavours should you expect from Castillo Aromatic?

Expect a clean sequence: lemongrass brightness first, a delicate floral aroma, then lychee sweetness. Our stated profile combines those notes. The coffee is processed in two extended fermentation phases, with fresh citronella and lemongrass juice introduced during the second phase. That process contributes to its aromatic character, although each brew can express the notes differently.

We source this Castillo from Liliana Caballero at Hacienda Casablanca in Santander, Colombia, and roast it in small batches in Adelaide, Australia. Its medium Omni-Roast is specifically positioned for cold brew, as well as filter coffee, espresso and long black. The result is a useful choice if you want to explore aromatic cold brew rather than a more conventional flavour profile.

Why can the same beans taste different when brewed cold?

Cold extraction changes the balance you perceive, rather than replacing the coffee’s underlying character. In a 2022 controlled sensory study of full-immersion coffee, tested cold brews showed more floral character and less bitterness, sourness and rubbery flavour than the corresponding hot brews. The sensory analysis also considered how brew strength and drinking temperature affect comparisons.

That distinction matters when you assess coffee flavour notes. Lemongrass, florals and lychee describe perceived aroma and taste; they are not pieces of those ingredients in the glass. The juice is part of this coffee’s processing, while the product’s stated cup profile describes how its character is experienced.

How can you keep the aromatic notes clear?

Start with a repeatable recipe. Use the same grind, coffee-to-water amount, steeping conditions and serving strength for each batch, then change one factor at a time. A 2019 study examined how grind size, extraction time and coffee type influence cold brew’s physicochemical and flavour characteristics. Its cold brew research supports treating those variables as part of the tasting result.

Roast level also matters. A 2026 descriptive study compared cold brews prepared with light, medium and dark roasts and found differences in their sensory profiles. The 2026 roast study examined other coffees, so use it as context rather than a prediction for Castillo Aromatic. Since this coffee is a medium Omni-Roast, taste it at your chosen serving strength instead of assuming roast alone determines the result.

Taste the brew before adding milk or sweetener, which can make delicate aromas harder to distinguish. If the floral note seems faint, compare a fresh pour at the same strength before changing the grind or steep. For cold brew coffee flavours, a simple tasting routine makes it easier to notice which adjustment changes the cup.

Explore a distinct cold brew profile

If you are looking for a cold brew with fragrant herbal, floral and fruit-like notes, our Castillo Aromatic is specifically suited to that method. It is a medium Omni-Roast, roasted in small batches in our Adelaide roastery and sourced from Liliana Caballero at Hacienda Casablanca in Santander, Colombia. Those details give you a clear starting point for deciding whether its profile suits your preferred cup.

Review the processing details and stated flavour notes for Castillo Aromatic coffee beans, then prepare a small batch using a consistent recipe. That way, you can judge its lemongrass, floral and lychee character at the strength and serving temperature you enjoy.
