How to display custom field label/value?

Question related to custom fields.
I defined a custom field named Titre (wine store) that display the alcool degree.
In the backend, I defined an option of titre as:
Value = 13.5 and Label =13.5°
I see that you display in product "titre" option list, the Label value.
Currently the code in listing_img_desc.php I am using is:
<?php echo $this->row->titre; ?>; this displays the value but I want to display the label info.
How can I obtain this result. I assume that the value is the key in database and the label is the field that must be displayed.
Thanks in advance for support.
