Wine and spirits costing: what time itself costs

Beyond ingredients and processing, maturation adds three costs that no other industry carries — capital sitting idle, the angel's share, and cellar space occupied for months or years.

Updated

The first half of this trade behaves like food processing: batch production, losses at each step, cleaning between batches. Read that guide first — the yield chain applies unchanged.

Then something happens that no other industry in this set has: the product **sits and waits**. And waiting costs money in three separate ways.

Three ways time enters the cost

CostWhat it isWhere it goes on the sheet
Capital tied upEverything already spent, not yet recoverableNo field — record three numbers in the notes, see below
Angel's shareEvaporation and absorption during maturationOne more step in the material yield chain
Space occupiedCellar or warehouse, tanks and casksPlant overhead, divided by time occupied

The second and third go straight onto the sheet. The first does not — and it is usually the largest, which is why it gets its own section.

The angel's share is yield, not scrap

The food guide describes losses as a multiplying chain: each step keeps a fraction of what the last handed it. Maturation is simply **one more step in that chain**, not a new kind of calculation.

Measure it on your own stock: volume in at filling, volume out at racking or bottling. Do not borrow an industry figure — it depends on your vessels, your storage conditions and your maturation period, all of which are specific to you.

The common error: recording it as scrap. Nothing went wrong — this is a property of the process. Filed as scrap it makes a well-run cellar look defective and destroys every comparison with anyone else. It belongs in the material chain.

Capital tied up: the cost with no field

Long maturation means paying for everything up front and waiting years to sell. During that time the money cannot do anything else. That is a real cost, but it is not a production cost — so the sheet has no box for it, and forcing it into one does damage.

Handle it by **not** entering it anywhere. Instead record three numbers in the verification notes: maturation period, value of a batch at the point it goes into store, and volume that comes out. Any reader can compute the capital cost from those three, using whatever accounting convention their business applies.

Pushing it into overhead breaks comparability in a way nobody can detect: your sheet looks more expensive than a competitor's and nothing on it explains why. Recorded outside the sheet, the number is preserved and the comparison still works.

The ten categories — from food, with three changes

CategoryWhat changes
Raw materialYield chain gains a maturation step. Casks used once are material; casks reused are tooling
ToolingReusable vessels — divide the cost across the batches they will hold, exactly like tool life
OverheadStorage space is usually the largest component, and it accrues with time, so divide by batches actually passing through in the period

The remaining seven follow the food processing guide. Packaging is heavier here than in most food categories — bottle, closure, capsule, label, carton — so keep it as its own visible line rather than folding it into a general figure.

Improving without shortening maturation

When the sheet shows time costing a lot, the instinct is to shorten it. But maturation time is often **what creates the selling price**, so shortening it can save cost and lose more revenue.

Three directions that leave maturation alone:

  • Reduce the angel's share through vessel choice and storage conditions — same time, more product out.
  • Increase storage density, so the same space holds more and the space cost per batch falls.
  • Smooth the fill and empty schedule, since storage cost accrues whether the space is full or empty.
The third only pays if space is actually the constraint. If your cellar has room to spare, packing it more densely saves nothing — the same test the bottleneck guide applies to every improvement.
