I have used Devans before and yes, they were my goto at one point! To my point earlier though: it took a while to find it.

There's a few others I know of. Lately I found shop in Bangalore that gets beans from Coorg. Reasonably priced and decent beans. Ainmane https://www.ainmane.com/. Shop is good. A little more expensive than Devans though I think.

Devan's is a good option though. Malakodu Estate has some decently priced coffee.

There's a website that aggregates all the coffee vendors, but the name is slipping my mind for some reason.
