Company email (November 2018)

"Unfortunately the person who answered your [October 2017] email gave you a general answer that is not correct overall.

"Some of our wines are Vegan friendly and some not.

"Our withes and rose wines are Vegan friendly because they are clarified with Bentonite, which is a natural absorbent aluminium phyllosilicate clay. Not animal product are used in the elaboration of these wines.

"Regarding our red wines, we are in the process to find some clarifying agent with the same results as the animal gelatin. As soon as we find it we will substitute the gelatin for it, and you will be informed.

"In the meantime I send you the list of all our products with the relevant information [list included, used for the list. -ed]"
