Here are a few resources that help me enjoy my wine:
I use are Vivino and Delectable. Both are available for Apple and Android devices.
Vivino is a crowd sourced wine rating app that allows you to rate wines and keep a record of wines you have tried. It also gives information about the winemaker, types of grapes used and the region in which it was produced.
Delectable also allows you to rate wines and keep a record of wines you have rated. However, this app also has articles about different wine styles, regions, and varietals.
They are both very helpful. If one app hasn't seen a particular wine that I have scanned, chances are the other one has.
