We keep the cards for every batch we have made. Here is what actually changes during a month of sitting in the dark, and why we will not sell anything before it.
The question we are asked most often, and very reasonably, is why a bottle takes five weeks when a blending counter in Malé will hand you one in twenty minutes.
The short answer is that they are working in oil and we are working in alcohol, and the two behave differently. The longer answer is what our cards show.
At day one, a fresh mix smells of three things: alcohol, the most volatile material in the formula, and whatever is present in the largest quantity. The structure a formula was designed around is simply not there yet. If you smelled our best work on the day it was mixed you would not buy it.
At day seven the alcohol has receded. The top materials have stopped dominating and the heart is beginning to be legible. This is the stage where a beginner would declare the batch finished, and where we have twice been tempted to throw one away.
At day twenty eight it is a scent. The base has come up underneath, the sharpness has gone, and the whole thing reads as one thing rather than as a list of materials taking turns. The difference between day seven and day twenty eight is smaller than the difference between day one and day seven, and it is the difference that matters.
Why it happens is not mysterious. Ethanol and the aromatic materials are settling into a stable solution, some of the more reactive components are quietly reacting with each other, and the most volatile molecules are distributing themselves evenly rather than sitting at the surface. Heat speeds it up and ruins it, which is why the batches sit in the dark at an even temperature rather than somewhere convenient.
After the twenty eight days we filter, because maceration drops a small amount of sediment out of almost every formula that contains naturals, and then the bottles rest for a week so the filtering itself settles.
Two cards are pinned above the bench. Both are formulas we described at day one as failures, in writing, and both became things we still make. That is the whole argument and it is why there is no express option here.
