The Huila production area is located in the southern part of Colombia's Central Mountains, close to the Cymbidium volcano, and has volcanic soil rich in minerals.

The Columbia River flows here, providing sufficient water resources and water vapor. The annual rainfall can reach 2000~3000mm. The superior geographical and climatic conditions make it a representative production area of high-quality coffee beans worldwide.

3. Front Street Brazilian Queen Manor Coffee Bean
Queen's Manor is located in the Morgiana production area in the state of Sao Paulo, Brazil. It is different from many large-scale production areas in Brazil that rely on quantity. The terrain here is higher, forming a relatively unique micro-climate. In addition, the manor manually picks coffee fruits with suitable maturity. Each batch is processed with a small amount of exquisite techniques, and the quality of the coffee beans produced are mostly high-quality. The variety of Front Street Queen Manor coffee beans is the rare local yellow bourbon. Since yellow bourbon coffee beans at high altitudes are denser and have higher glucose content, Front Street’s roasting idea is to highlight the classic mellow aroma of Brazilian coffee while showing off the sweetness of bourbon itself, so medium-dark roasting is used.
