I was wondering if you can get a Sunset Sasparilla Star Cap if you made your own Homemade Sunset Sasparilla?

You can make a bottle from some plants and an empty bottle and a regular cap. So if the developers paid attention to the detail, I shouldn't be able to get one by drinking a homemade Sunset Sasparilla. But part of me is hoping that they didn't to do that.

So far I made and drank 10 bottles of homemade Sunset Sasparilla, but no Star Cap, yet.
