Frequently asked questions

Does V5 Coffee’s China Blue Iris contain actual flowers, perfume, or artificial additives?
No, our China Project One Light: Blue Iris single origin coffee contains absolutely zero flowers, perfumes, syrups, or artificial flavour additives. The elegant notes of soft violet, distinct blue florals, stewed pear, and sugarcane are achieved entirely through natural organic chemistry and precision processing. When our selected yeast cultures break down the coffee cherry’s natural sugars during anaerobic fermentation, they create volatile aromatic compounds that chemically mirror those found in nature. Your brain recognizes these high-definition compounds, perceiving a beautifully complex floral profile derived purely from the coffee bean itself.
What is the anaerobic yeast-control processing method used for the Blue Iris coffee?
The China Blue Iris utilises an advanced anaerobic yeast-control fermentation process meticulously managed in the Yunnan highlands. Raw coffee cherries are sealed inside airtight, oxygen-free tanks where specific, isolated yeast strains are introduced. This targeted yeast-control processing method focuses entirely on elaborating the bean’s inherent floral elegance and high-definition flavour clarity. By eliminating oxygen, standard spoilage micro-organisms cannot survive, allowing a slow, incredibly clean breakdown of fruit mucilage that forces the coffee seed to absorb delicate floral precursors without any of the heavy, boozy "funk" typical of traditional anaerobic processing.
What is the best home pour-over recipe to capture the delicate notes of Blue Iris?
To fully unlock the elegant blue florals and clean mouthfeel of this light filter roast, we highly recommend a manual filter brewing method such as a V60 or Kalita Wave dripper. Use clean, filtered water heated to 93°C–94°C to gently extract the volatile aromatic compounds. We suggest our standard 1:15 brew ratio, specifically 20g of medium-fine coffee grounds to 300g of water, with a target extraction time of 2 minutes and 30 seconds. This parameter set prevents over-extraction, ensuring that subtle notes of stewed pear, lychee, and sugarcane remain perfectly articulate and clean in your cup.
Where can I buy experimental yeast-control Blue Iris coffee in Australia?
You can buy our exclusive China Project One Light: Blue Iris single-origin coffee online directly through V5 Coffee. As a specialised Melbourne coffee roaster, we source these rare, highly limited experimental nano-lots directly from progressive estates in Yunnan, China. By roasting locally in Melbourne and distributing directly to home filter coffee enthusiasts across Australia, including Sydney, Brisbane, Adelaide, Perth, and Hobart. We eliminate the need for niche international importers and guarantee peak freshness on your brew bar.
How fresh will the Blue Iris filter coffee beans be upon delivery across Australia?
To maximise aromatics and flavour clarity, your Blue Iris coffee beans are roasted and dispatched directly from our Melbourne roastery within 24 to 48 hours of your order. We heat-seal all our coffee in specialized valved bags to completely lock in the volatile, fragile floral compounds during transit. Your beans will arrive just as they hit their absolute peak filter brewing and degassing window. Additionally, free standard shipping is available nationwide for all qualifying orders.
How does the Blue Iris taste profile compare to standard anaerobic coffees?
Unlike traditional anaerobic coffees that often feature a heavy, winey, or over-fermented "funk," the China Blue Iris is incredibly clean, perfumed, and elegant. Thanks to the precise yeast control processing method utilised by the Project One Light lineup, the bright acidity is beautifully balanced by an intense structural sweetness. Home filter brewers can expect an extremely clean mouthfeel and a highly defined, tea-like body characterised by soft violet, delicate blue florals, and a crisp, lingering sugarcane finish.
