I am planning to cook a French bœuf bourguignon, but a vegan version. Apart from the wine and the herbs, I recall that the butter had quite an impact on the vegetarian version that I previously made.  When reading about vegan butters online the goal is usually to aim for a certain consistency, for baking etc. Is there a way to add butter flavor to this vegan recipe? 
I actually substitute high quality olive oil for everything in my cooking now. There is a 'butter oil' which is olive oil pressed/infused with celery seed and lettuce extract which actually has a remarkably similar flavor profile. So if you live near any specialty olive oil shops that is definitely something to ask for! It's great on popcorn too. And better than all these funny hydrogenated oils.  https://unrefinedolive.com/collections/infused-olive-oils/products/butter-infused-olive-oil?variant=39727564114 This is the product I was talking about.
