So many really, especially St Estephe/Northern Medoc is a really good hunting ground.
I have enjoyed Lilian Ladouys, Tour de By, Greysac, Citran, Belle Vue (LB), D’Agassac, Petit Bocq, Potensac, Lanessan, Liversan, Marjosse, Le Crock in that style.
Not your original request but really a lot of value is to be found in the Durantou wines Chenade/Cruzelles/Montlandrie/Saintayme although they do tip into 14% territry. Lovely wines though and properly ageworthy.
Northern Medoc is a happy hunting ground for good left bank Bdx and (still just) sensible prices. I would echo all the above plus Larose Trintaudon, a French supermarket staple, and Tour Haut Caussan, a personal favourite and lovely people. Drinking 2009 THC & tried 1 x 10 still early. 15 LT is going well.
I dont think you can go wrong with decent (Haut) Medoc Cru Bourgeois in a good vintage
A very modest chateau, but a great vintage ( and a very reasonable price ) - just finished a bottle over two days and was at it’s best 6 to 12 hours after opening.
