Hi AmnA,
Clemence Togo and Fjord are all grainy....
All are cow lethers...Togo and Fjord can both have veining but not necessarily (none of my togo pieces have veining). This is due to how the leather is treated (frozen) and not apart of the skin. Clemence comes from a baby bull, fjord from buffalo, and togo from an adult bull. The size in graining really has little to do with the leather, as some people think togo has larger grains than clemence. Clemence is the softest of the three. Fjord is the most rigid.
Barenia is barenia because it is an analine leather that is tanned with oils. Vache Natural is also analine leather with vegatable dyes (non oily). Analine means there is no prtective layer over the leather to prevent staining.
They are smooth leathers, but so is Box, Chamonix, Swift, Evercalf and a few others. All these leathers are treated with a protective coating to resist stains.
Chevre comes from goats and yes depending on the goat the grains may differ. Chevre has a sheen to it as does Box.
Box and Camonix both come from cows. Box is the shinier version or Chamonix.
