To add bottle racking details you first need to identify the wine you would like to add the information to, either by searching for the wine, scanning the wine label, scanning the Vinfolio barcode, or looking up the wine in Your Cellar.
Once you have identified your wine, tap the cellar site square on the product detail screen that you would like to add racking details for and then tap 'VIEW BOTTLES'.
Tap 'Add Racking Details' and specify the details of your bottle location.
You can also modify the names of your bottle racking taxonomy by clicking 'EDIT FIELDS' and moving around the order, deleting existing fields, or adding more fields. To create a new field tap '+ ADD MORE' followed by 'CREATE NEW'.
