Related products based on dynamically populated tag

Hi there,

I’m wondering if there is a way to dynamically add a product’s single tag within an IF statement? On our store, we have products that have a single tag. This tag is used to group products as ‘fake variants’ on an individual product page.

The current (convoluted!) liquid I have so far is:

{% if product.tags.size > 0 %}
  
     
  

{% endif %}

At the minute, all products with a single tag appear.

Is there something that would function the same as this below (if it were possible in liquid):

{% if product.tags contains {{tag}} %}

Thanks for taking the time to read this!
