mobile – When to remind with “Remind me later”?

What are some things I should consider and think about that will help me figure out when we should remind the user of something?

For context: Our mobile app is basically a wine collecting app. When users tap to consume their bottle in the app, they can make a note about the wine which will be stored in the archive. We want to be able to give them the option to write the note at a later time, hence why we want to put in the “remind me later” button. I’m trying to think of when would be the best time to remind them (push notification) of this? After 3 hours? 6 hours?
