Answer 1

It is true that AngularJS uses keys to associate DOM nodes with items. So, you can solve by adding "track by $index".

It will look like this

ng-repeat="wine in wines track by $index"

Answer 2

Occurs if there are duplicate keys in an ngRepeat expression. Duplicate keys are banned because AngularJS uses keys to associate DOM nodes with items.

This means that $scope.wines have some values which are duplicate.
