Here's a free glass-bottle growler mockup for your projects. There are several layers of smart objects where you can add your graphic label to the bottle, add type that shows through the glass growler bottle, and you can adjust the bottle cap and background color.
Feel Free to use this in your personal projects with attribution and contact for any other use.
As always, I would love to see what you're working on or designing, so feel free to reach out or connect with your finished design. Thanks!
