When you perform any search, the most often used of which are usually accessible with a single button click, the results are listed in an Index Listing and this one shows all wines suitable for drinking now.
You will notice that in the Maturity column wines that are Improving (Cyan) as well as wines that are Mature (Yellow) are listed.
This is because wine does not magically become drinkable at a certain date but is drinkable over a span of years and WineBase is clever enough to recognise this obvious fact.
From this screen you can view all of a wines details in the Page Display or edit any details, remove a single bottle with one mouse click, print, export to a comma or tab delimited text file or even as HTML. (Jan 1992)
