Incense Way Part 1: How to Choose Good Agarwood Material

Incense Way, Part 1: How to Choose Good Agarwood Material — A Four-Step Buyer's Method

• **Purpose first**: daily electric-censer use → chips and small shell pieces of plantation or second-tier regions; powder for sticks → oil-rich chips; tasting sessions → intact shell pieces from authentic regions; collection → whole sinking-grade material with lab reports.
• **Step 1 — smell the base and the finish**: low-temperature (100–120°C) electric censer trial; good material has three stages (opening, steady middle, a finish that "lands"). A single blast of sweet pungency with no finish suggests oil-soaking or synthetic fragrance.
• **Step 2 — read the oil lines**: natural resin follows vessels and grain with gradual transitions; uniformly jet-black, hard-edged material signals pressing or oil injection.
• **Step 3 — interrogate the source**: region (core vs. broader), resin-formation method (wild / fungal inoculation / whole-tree induction), and lab certification. Pharmacopoeia benchmarks: alcohol-soluble extractives and characteristic chromatogram.
• **Step 4 — budget by purpose**: 60% on reliable daily material, 30% on worthy upgrades, 10% as tuition; keep a tasting ledger.
• **Pitfalls**: density alone doesn't decide quality (fine Hoi An material often floats), punch ≠ quality, story ≠ proof, and "too cheap to be true" auctions.
• Terminology: agarwood = 沉香; kyara = 奇楠; *Aquilaria sinensis* = 白木香; sesquiterpenes = 倍半萜; chromone = 色酮.
