The formula in the bottle is not the first formula we made. Development is a structured iteration process — each trial blend is evaluated over days, each evaluation generates specific adjustments, and the formula is not locked until every act performs as the brief specifies.

Formula development takes place in London using the received perfume oil from our labs. Each trial blend combines the aromatic concentrate with ethanol and fixatives in the ratios specified by the current iteration of the formula. We begin with the 30-30-30 structural framework — one third each of top, heart, and base material weight — and adjust through controlled iteration. One variable changes at a time. The ratio of a key material, the fixative level, the balance between the concentrate and the ethanol carrier. Changing multiple variables simultaneously produces results that cannot be diagnosed — you cannot know which adjustment caused which change.

WHAT WE DID

Trial formulas are evaluated at 72 hours and at one week. The 72-hour read confirms whether the act structure is directionally correct. The one-week read gives the first meaningful integration impression — whether the heart is asserting correctly, whether the base is anchoring without dominating, whether the ethanol and fixative system is performing as intended. Development continues until all three acts satisfy the brief. Some formulas resolve in three iterations. Some take ten. There is no target number. The formula is locked when it is right, not when it is convenient.

WHAT COMES NEXT

Once the formula is locked, the full batch is blended in London. The perfume oil from our labs is combined with pharmaceutical-grade ethanol and fixatives by hand. This is where the EDP is completed.
