Casas del Bosque has some vegan options

Jazmin's email (December 2022)
"I was at the Casas del Bosque winery in Chile yesterday and would like to update the information.
The sommelier informed us all wines are now clarified with albumin, except for the sparkling wine Bo, an Extra Brut sparkling wine, the only one the vineyard makes, uses bentonite and would be considered vegan friendly.
They are looking into alternative methods for clarification but the vineyard has not settled on any yet."

Company email (July 2018)
"Lamentablemente debo informarte que nuestros vinos no son aptos para veganos. Todas nuestras etiquetas indican que “contiene leche, huevos y sulfitos.”
Dejamos de usar gelatina, aunque se sigue usando ictiocola en algunos vinos, por lo que en estricto rigor tampoco son aptos para vegetarianos."

[Google translation: "Unfortunately I must inform you that our wines are not suitable for vegans. All our labels indicate that "it contains milk, eggs and sulfites."
We stopped using gelatine, although ictiocola is still used in some wines, so in strict rigor they are not suitable for vegetarians either."]
