I tried the two pictured here, le beurre doux and le beurre au sel fumé. And yes, it is the best butter. I don't think it's cultured, which would be rare for high-quality French butter, because the sweet butter does not have the characteristic sour tang; it's like the best non-cultured butter imaginable. And the smoked salt butter was little short of divine, on toast and in tiny slices placed in the middle of a split radish.
According to Bordier's web site, the special complex buttery notes are a result of 15-25 minutes of kneading (malaxage) in a teak vessel and the artisanal barattage process, which I don't understand at all. The final bars are shaped by hand using wooden spatulas on wooden tables, by workers who must have "great dexterity and clock-like consistency." Charming if nothing else.
Apart from baking, I don't actually use much butter, but I am tempted to sample every variety of Bordier's, and there are quite a few. Here's the current list from their website:
- Le beurre doux
- Le beurre demi-sel
- Le beurre salé
- Le beurre au sel fumé
- Le beurre aux algues
- Le beurre au Yuzu
- Le beurre au Piment d’Espelette
