Classifications now have their own page
Classifications have moved from a tab on the encyclopedia to their own page at /explore/classifications, so the link in the Explore menu now opens the list reliably — previously it changed the address bar while leaving the previous page on screen. The new page filters by the things a classification actually has: search by name or by a level such as Grand Cru or Kabinett, then narrow by country, by what the system classifies, or by learning level. Filters are kept in the address bar, so a filtered list can be bookmarked and shared. The grape and blend dropdowns are gone, since no classification is tied to a grape. The varieties page is now titled Grape Varieties and Blends.
