Everything on the site
Nineteen pieces across five sections.
- The county the mountain sits inAlishan is a range in Chiayi County rather than a single peak, and the growing area spans a considerable altitude range within it.
- Cloud that arrives on a scheduleThe daily cloud belt cuts direct sun and holds the temperature swing that high-mountain tea depends on, which is a growing condition rather than scenery.
- Tea grown above a thousand metresTaiwanese high-mountain oolong is defined by altitude and by a partial oxidation that is stopped deliberately, and Alishan is one of the named growing areas.
- Three different rulebooks, one wordThe EU organic regulation, the USDA National Organic Program and Taiwan's Organic Agriculture Promotion Act of 2018 are separate legal instruments with separate requirements, and equivalence between them is negotiated.
- Somebody has to sign itCertification is issued by accredited bodies rather than by governments directly, and IFOAM sits above them as an umbrella rather than as a regulator.
- A list of what may still be usedOrganic production permits a defined list of inputs, and copper compounds are the long-standing argument on it because they are permitted and they accumulate.
- Why the land waitsLand must be managed to the standard for three years before its crop may be sold as organic, which is a residue and soil-biology argument rather than a formality.
- Nitrogen without a bagLegume cover crops and green manures supply nitrogen through fixation, which is the core agronomic substitution the standard requires.
- Keeping the neighbour's spray outBuffer strips and hedges exist to keep drift off certified ground, so a certificate constrains a farm's boundary as much as its practice.
- A visit, a file, and a decisionCertification is renewed by an annual inspection covering records, inputs and traceability, and unannounced visits are part of the scheme.
- Chemistry as a check on paperworkResidue sampling tests whether the file matches the crop, and detections trigger investigation rather than automatic withdrawal.
- What happens when it failsA certificate can be suspended or withdrawn, and the consequences run to the whole supply chain that had been relying on it.
- A batch has to be followableLot coding and mass-balance checks are how an auditor tests that the volume sold matches the volume that could have been grown.
- What the studies actually sayMeta-analyses report differences in some secondary metabolites and in pesticide residues, and much smaller differences in the macronutrients people assume.
- The gap, and where it is largestOrganic yields are generally lower, with the gap varying widely by crop and by system, and the comparison is contested on methodology.
- Per hectare against per tonneEnvironmental advantages measured per hectare often shrink or reverse when measured per tonne of output, which is why the two framings give different answers.
- A line built to take timber downThe Alishan Forest Railway was built from 1912 for logging, with switchbacks and spiral sections to manage the gradient.
- A halfway town that stayedFenqihu grew as a service stop on the line and survived the end of logging as a waypoint rather than as a destination.
- What the line was built to removeThe old-growth cypress and cedar the railway existed to extract are the reason the remaining stands are now protected.
