Lang Wines (2013 Vintage) is Vegan Friendly

Company email (January 2016):
"All of our 2014 & 2015 vintages are vegan friendly as we do not use any animal byproducts for our wines."

Company email (June 2014):
"All of our current 2013 vintage wines do not contain any animal ingredients and are Vegan friendly :)"
Q: "Just a quick follow up question, would the 2012 and 2011 vintages be ok as well? Or do you vary based on the year, etc...?"
A: "We have a new winemaker this year... He has assured me that his wines are all vegan friendly. I believe our other vintages are also fine but since that winemaker is not here anymore I cannot guarantee that they are vegan friendly."
