What that suggests to me is that you like the stronger taste generally generated by a darker roast. French Roast is pretty much the darkest roast you want. (Much beyond French Roast and what you have are tiny charcoal briquettes!).
As you know, French Roast just describes the darkness of the roast, but tells you nothing about the beans used.Now that you know the kind of roast you like, you're next goal is to find a better bean blend than the supermarket beans. So you might look around for better beans in a French Roast, or the darkest roast offered for that blend.
Yes, indeed, agreed.
When I am in an - ah - relatively civilised, cultivated, urban.....location, (such as my home in western Europe), I try to find small producers of coffee (often stocked by very good delicatessens), the sort of individuals who contact & contract small producers of good quality beans, (often ethically sourced and/or organic, too) and proceed to import small quantities of say, such single estate beans, or a a bean grown in a specific region, or terroir, pay a decent price to the grower, co-operative, and roast them, themselves.
These sort of companies often have varietals - in beans, regions, countries, continents, and so on; some of their offerings lie in the 'dark roasted' range, others are 'merely' full-bodied, while yet others, are milder still.
I'd suggest that you try to find one of these small, high quality (and often award winning) companies, and find what they offer under the heading of 'French Roast'. I'm willing to bet that it will be a lot better than some of the supermarket offerings (not that there is anything wrong with that in a world where choice is limited, as I have learned recently, when LavAzza was a sublime luxury in a world where colleagues thought Nespresso was the acme of civilisation and sophistication........and that I should display due gratitude (I did, I did) to be offered a cup of same.......)
Edit: I like the 'tiny charcoal briquettes' quote......consumption of such charred cinders may well leave - deep and lasting - memories in the mind.....
