WIP Volume by beer type

Is there a way to create a report or see the volume of the WIP (work in progress) by beer/product type?

You could use the Beer batches (gyles) Raw data explorer report to view the volume of your in-progress batches. Go to the report and add a field for total volume. Then add a BrewwQL filter for status = “In-progress”.
This will show you the volume of each in-progress batch you have.
Does this show you what you need?
