I decided to go with the Deux sincere I already know what the Voyer Extra taste like.

This cognac is quite good. No alcohol burn at all at 51% abv. Compared to the Audry Aristide, this is smoother and only cost half as much. I am glad I took a chance with it. And sorry to say, but the rancio is pronounced with this one

The nose: smell of ripe pineapple, cigar box, leather chair. Rich.

On the palate: rancio. Quite yummy, and smooth for a 51% abv. Complex and layered. Mid length on the tongue. Taste of mango and that ripe pineapple. Christmas cake.

Here is more info from their booklet.

Wow. Let it sit a while longer, and with a few drops of water, the magic is really released.

That gives some more information. I wonder if this is not a typo. Mr. A. Jullien (André Jullien, with two 'l'-s) is the owner of Logis de la Mothe, who stopped private sales in 2017. I don't know any other André Julien or Julien André.
I guess the second family bought the cask, hence deux familles. If this is the case, only this second family can confirm my hunch if this was indeed from André Jullien.
Maybe time will tell.
