Bottles

download
Bottles makes it fun to manage your wine collection! The app was designed, built, and tested by wine enthusiasts. Bottles is focused on the experience of picking your next bottle of wine to enjoy.

Add your wine to the Bottles app, specifying the location you store each bottle. Use the app to view lists of your wine, pick a bottle to enjoy, see where it is located, and mark the bottle as opened. Later Bottles can remind you to rate that wine, helping in the future to pick your favorite wines, and helping you to purchase more of your favorites. Wines can be viewed by varietal, winery, vintage, favorites and more. List can be easily sorted and searched.

Since your wine data is stored in iCloud, you can safely access your collection from all your iPhones, iPads and Macs. Bottles may be used when not connected to the internet, and your changes will sync the next time you run Bottles with an internet connection.
