What Happens When You Brew Costa Rican La Diosa Estate Geisha with High Water Temperature?

A few days ago FrontStreet Coffee received a new batch of Costa Rica La Divina Geisha. These beans carry rich floral aromas, and the green beans look elongated with a light green color. Unlike the usual grassy smell of green coffee, La Divina Geisha shows not only grassy notes but also refreshing scents of bergamot and berries.

Cupping revealed floral, lemon, honey, and fruit tea flavors. FrontStreet Coffee had previously used water between 90-91 degrees C to extract Geisha, so today we wondered what would happen with slightly higher temperatures.

93 degrees C

Parameters: 15 g coffee; medium-fine grind (BG 5T: 58% pass-through rate on a China-standard #20 sieve); 1:15 coffee-to-water ratio; segmented pour-over, with technique kept as consistent as possible.

Pre-wet with 32 g of water for 30 seconds. Make the stage division at 127 g. Continue pouring to 227 g as the water level is about to expose the coffee bed, then remove the dripper (timing starts at the pre-wet). Extraction time: 2'00".

Flavor: citrus, berries, oolong tea, with pronounced tea-like notes in the finish.

92 degrees C

Parameters: 15 g coffee; medium-fine grind (BG 5T: 58% pass-through rate on a China-standard #20 sieve); 1:15 coffee-to-water ratio; segmented pour-over, with technique kept as consistent as possible.

Pre-wet with 31 g of water for 30 seconds. Make the stage division at 125 g. Continue pouring to 225 g as the water level is about to expose the coffee bed, then remove the dripper (timing starts at the pre-wet). Extraction time: 1'59".

Flavor: floral, oolong tea, citrus, plum, cream.

91 degrees C

Parameters: 15 g coffee; medium-fine grind (BG 5T: 58% pass-through rate on a China-standard #20 sieve); 1:15 coffee-to-water ratio; segmented pour-over, with technique kept as consistent as possible.

Pre-wet with 34 g of water for 30 seconds. Using a small water flow, pour 96 g to reach 130 g, then make the stage division. Continue pouring to 225 g as the water level is about to expose the coffee bed, then remove the dripper (timing starts at the pre-wet). Extraction time: 1'56".

Flavor: floral, citrus, lemon, oolong tea, with distinct bergamot notes in the finish.

90 degrees C

Parameters: 15 g coffee; medium-fine grind (BG 5T: 58% pass-through rate on a China-standard #20 sieve); 1:15 coffee-to-water ratio; segmented pour-over, with technique kept as consistent as possible.

Pre-wet with 34 g of water for 30 seconds. Make the stage division at 130 g. Continue pouring to 225 g as the water level is about to expose the coffee bed, then remove the dripper (timing starts at the pre-wet). Extraction time: 1'56".

Flavor: overall the florals are prominent, with lemon fruit tea. The first sip reveals citrus, cream, and honey, with a sweet, lingering aftertaste.

Conclusion

Brewing at four different temperatures, every extraction highlighted the prominent floral and tea-like character of this La Divina Geisha. At 93 and 92 degrees C the coffee had relatively simpler flavor layers but a fuller, thicker mouthfeel, well suited to those who prefer rich, full-bodied textures. At 91 and 90 degrees C it showed more layered flavors leaning toward fruit tea, with a cleaner mouthfeel, better suited to those who prefer floral notes and light sweetness and who are looking for more complexity.

FrontStreet Coffee Recommendation

If the floral, tea-like quality of this La Divina Geisha is what you enjoy, FrontStreet Coffee's Panama Esmeralda lots will be a natural next step. The Esmeralda Green Label (Private Collection) blends several plots to showcase the estate's signature high-altitude Geisha character, and at a more accessible price it is the best-value introduction to the Esmeralda style. The Esmeralda Red Label (Esmeralda Special) is grown at 1,600-1,800 m, cups above 90 points, and comes from a single plot with its own lot number, the finest expression the estate offers.

For a gentler first step into the variety, FrontStreet Coffee's Panama Boquete Geisha is an entry-level lot that still delivers the classic Panama profile: tangerine-honey sweetness, an oolong-tea texture, fine fruit acidity, and clear layers. As the experiment above shows, keeping the brew water at 90-91 degrees C preserves those delicate florals, so use the 90-degree or 91-degree recipe when you want the most layered, tea-forward cup.
