Best flavour French beans

Cobra is a climbing French bean that I will be tring this year, it's supposed to be prolific and tasty!

Not a squeaky bean fan but brother in law is and rates Blue Lake for growing and eating.

As a climbing bean I always grow Cosse Violette, it is a long, purple, bean wit excellent flavour and texture. Dwarf beans, I'm still struggling with. haven't found one with an outstanding flavour that performs well.

Generally it is a matter of personal taste, I grow both climbers and dwarf green, purple and yellow!

The climbing yellow ones are fairly tasteless, but the dwarf yellow are sweetest of all!

I'm really glad to hear that as this year I too am trying all 3 colours in dwarf beans (including, I hope, sweet yellow ones  ) plus my favourite Climbing Blue Lake and a heritage climbing one called Mrs Fortune's Beans that I was lucky enough to get in the Pass the Parcel 

A did a few blue lake and cobra last year, seemed ok, not a great yield I thought.  Will try again as I've got seeds left, but watching this thread for any other suggestions!
Dwarf Hestia and yellow wax always work for me if you can keep the slugs off.  I added a late sowing as a green manure for the last two years after the early spuds come out and that's always ended well for me- beans in Oct and something to dig in too.
Cosse Violotte looked gorgeous but I didn't like the grey colour it goes when cooked so may not bother again.

I grew some The Prince last year, which are a flat-pod dwarf bean and they were tasty and prolific, and Speedy for an early crop in the unheated mini-tunnel were delicious too (round pencil pod type)
