A single cask release and a vague history
Marketing wants to tell the story of a single cask release: the oak, the sherry it held, the bodega, the fill. The cask number is known. The fill sheet says 'sherry butt'. The supplier invoice from years ago lists a batch of butts without numbers. Was this a first fill or second? The blender thinks first fill, but the sheet does not say.
For everyday blending the same gap matters. How a cask behaved on its last fill is the best guide to how it will behave on the next, but that history is not joined to the cask.
Why cask histories go missing
Casks arrive in batches, and invoices and certificates describe the batch, not each cask. Your own cask numbers are applied on arrival and may not be linked back to the supplier's batch. Each refill starts a new fill record, often with a new sheet. Rejuvenation or re-charring is done by a cooperage and noted on their invoice. The pieces exist but are never attached to the same cask.
- Supplier invoices describe batches, not individual casks.
- Previous contents are recorded in general terms.
- Fill number is not tracked consistently.
- Cooperage work is on invoices, not on the cask record.
- Each fill starts a fresh record with no link to the last.
What an unknown history costs
Blending decisions made with less information. Release claims that are vague or have to be checked by hand. Casks used beyond the point your blender would want because their fill count was unclear. And cask purchasing that cannot learn from which suppliers' casks performed well.
What you may say on a label is for you and your adviser. We make sure the facts behind it are recorded.
A cask record from purchase to last fill
- On arrival, each cask batch is booked in with supplier, invoice, certificates and the supplier's details on wood, previous contents and origin.
- Your cask numbers are applied and linked to the batch, and any per-cask details from the supplier are attached.
- Each fill is recorded on the cask record: spirit, run, date, strength and volume readings your team takes, and fill number.
- Emptying, re-racking and cooperage work are recorded on the same record.
- Sampling notes from maturation are shown alongside the fills.
- Blenders can search casks by wood, previous contents, fill number, supplier and age.
- Supplier performance can be reviewed from how their casks' spirit developed, based on your team's notes.
| Detail | Where it was | Where it is now |
|---|---|---|
| Supplier and batch | Invoice | Cask record |
| Previous contents | General note on fill sheet | Cask record from arrival |
| Fill number | Often unknown | Counted from each fill |
| Cooperage work | Cooperage invoice | Cask record |
| Maturation notes | Separate sampling notes | Alongside fills |
Cask stories you can trust
Each cask has one record from the day it arrived. The blender sees fill number and past behaviour before choosing casks. Marketing tells a release's story from recorded facts. Purchasing learns which suppliers' casks you like. And new staff do not have to learn cask histories from the person who has been there longest.
Does this sound like your cask records?
- Supplier details are on invoices, not on casks.
- Fill numbers are uncertain for older casks.
- Cooperage work is not recorded on the cask.
- Single cask stories are pieced together by hand.
- You cannot compare suppliers' casks over time.
