Cognac and the other old spirits follow the whisky rule: upright, dark, know the fill level. In the overview [Security for collectors](/artikel/sicherheit-fuer-sammler) it is the same physics as [Whisky](/artikel/whisky-sammlung-sichern), with different labels.

## What gets ruined without a thief

Light and heat, a leaking capsule, a cellar that gets hot in summer. You store upright and you write the fill level down. A bottle you open for a meal leaves the collection list.

## When someone comes

The bar in the living room is visible. The bottles with a receipt and a price stand somewhere else, locked, without a strip of the vintages on the door. In the Radar this is not a word of its own.

## The folder

House, designation, age or bottling, fill level, open or closed, receipt. Photo of the label and the shoulder.


## Häufige Fragen

### Put it next to the whisky?

Yes, if both stand upright, dark, and cool. On the list they stay two stocks.

### Opened bottle, still collection?

Only if you keep it that way and the fill level is right. What has been drunk is less.

### Certified safe?

A climate cabinet, maybe. A hot document safe, no.
