How it was read
By CaskGrail's reader, from the label images; each fact is the label's own statement
Source
US TTB label approval (COLA), not a shelf listing or a release announcement

A label approval is permission to bottle. It isn't an announcement or a release date. The name on the approval is whoever applied for it, which is not always who distilled the whiskey. How CaskGrail reads labels
