This is a 14 year old blog post about one man's quest to find the lost colby of his youth. After a change to the colby standard by the Wisconsin Department of Agriculture in the mid 70's the name colby became usable for any old mild cheddar. The original was made completely differently from the way you make cheddar, with water and continuous stirring being used to cool the separated curd. After the nomenclature change lobbied for by big cheese the dull and boring product you can get in every grocery store became the only colby most people ever see.
The blog post says they've only found 3 Wisconsin cheese makers who still make the OG style. I've tried Hook's and Widmer's (both have an assortment of insanely delicious cheeses) but I'm not familiar with Gile Cheese & Carr Cheese Factory although it looks fantastic.
