Weinmaleins is an app with which you can remember which wine you liked or didn't like. A photo of the bottle makes it easier to recognize. So that not everyone has to type in all the data, the data that has already been entered is made available from our crowd-sourcing database. Our administrator checks the accuracy of the data and deletes incorrect data or data at the user's request. This means that if you scan a barcode, enter the winemaker and wine information, and take a photo of the bottle, then a wine lover can get that exact information when he or she scans the same barcode. You can rate the wine and say what it tastes like, but that remains secret.
