Hey Claire,
I’m afraid neither of these things are currently editable. However, they are more for reference and won’t actually impact anything significant.
Regarding ingredient sub-type, instead of selecting ‘Ingredient’, if you select ‘Other’, you can actually create your own ‘Other’ sub-types, so this may be useful for you. To do this, go to Inventory > Tools & options > Other stock item sub-types. We have an open feature request for Allow for custom ingredient sub-types - if you’d like to see this added, please can you vote for that request.
As for container types, if you want to keep a separate stock of different coloured cans, I’d definitely suggest creating a different container type for them. Otherwise, you’ll find it tricky to keep track of stock later down the line. One thing that’s worth mentioning is that if you (or plan to) use the Breww Trade Store, you’ll want to add a more generic name override for this, as the colour of the can probably isn’t relevant to your customers.
