title: Adding product variant title in shopify
body: <p>I've got a few products that have different variants - i.e. Colour, Size, etc.</p>
  <p>I'm trying to output the parent(?) variant title using - {{ variant.title }} but that's only outputting the variant options themselves  i.e. Small, Medium, Large for Size.  Is there a way to output the &quot;Size&quot; title and not the individual variant titles.</p>
  <p>Sorry if that's confusing, I know I'm in the close but maybe in the wrong ball park!</p>
