How do I add custom fields to layered navigation filter?

[jucedupp]

I have done an override for products and added an extra field called "Vintage."  This all works fine and the vintage is saved against the product. 

 

What is the easiest way of adding this field (Vintage) to the layered navigation module? 

 

In other words, I would like a select list (dropdown) with the vintage years, where if a customer selects a year (vintage), it filters on that.

 

Any pointers on getting that done as simply as possible without using features?

 

Regards
