Get notified when it's ready to eat
There's a window of time when the flavor comes into its own. We'll let you know when you've entered that "harvest window," so you never miss the moment to open it.

Keep a record of your observations
Leave a photo and a short note, and it becomes a clue for your next batch. You can even compare it side by side with last year's.
The app isn't available to download yet. We'll announce it on this site as soon as it's released. In the meantime, please enjoy Learn and Craft here on the website.
