You can always access the wines you've previously received. All you have to do is login and head to your Past Wines.
Any bottles that you haven't rated will be at the top and if you can't find a particular bottle, you can try searching by the month it was delivered.
You can then give it a star rating (out of 5) and leave a tasting note or review in the notes section, which you'll always have access to.
Once you've rated a wine, we'll take that as meaning it's been drunk and it will automatically move down into your Already Drunk section, which again you'll always be able to access.
