title_body: Why aren't all wines vegetarian?
upvoted_answer: So a wine that advertises itself as vegan or vegetarian used an alternative to fining agent?
  That's true. There are alternatives to the use animal products for fining. Examples are clay, silica and vegetable plaque.
  Do some vegan wines simply skip the fining phase, or do all wines go through fining?
  There are a lot of wine makers that prefer not to fine their wines. Not necessarily because they are animal friendly, but because they believe this process deprives the natural flavour and texture. Those wines are often called &quot;natural wine&quot;.
