To find the details of a bulk wine that is no longer in a vessel there are a number of different ways to locate it.
If the product was bottled and that item is still in stock, find that item in the Stock Overview open the Components tab. In here there will be a link to the bulk wine that will take you back to the product itself. This will show as an Historic Revision of the wine, with all of it's details at the time it was bottled.
Alternatively if the wine has been dispatched, to get to that same place, go to Search > Dispatch search and find the dispatch of the product before selecting it and clicking View wine details.
From here you can get back to the Relevant history of the wines. You can also run reports such as the label integrity report or the status report available under the Action or Report menu.
If you are in search of a report with more details you can run the Stock dispatch report, under Reports > Inventory.
