What is the trick - Caulier 1842?

[Dima German]

Caulier Blond & Brune brewed by Caulier Developpement (La Maison Caulier) at De Proefbrouwerij are quite famouse. On the^  http://www.ratebeer.com/brewers/caulier-developpement-la-maison-cau... we could see Caulier Extra, alk 4,3 discribed as lager by two participant. No information what it is officially I can find. Moreover we here (Kiev, Ukraine) have got "the full set", including Caulier 1842, 4,3abv with the taste quite as Extra, but bottle fermented, see picture:

Have someone any idia what is it?

By taste it is very close to Wit beer, with residual yeast on the bottom, non filtered as well as Extra.

Official web site of www.caulier.be looks dead from 2009, there are a lot of degustation of brune & blonde at beer pages, but 1842 looks like a que.

Need help.
