Cornell & Diehl can trace its heritage across more than five decades and three names. When Craig and Patty Tarler purchased Amar Blending, it was a dilapidated, failing business. It had declined to such a degree that Mr. Tarler was able to pick up the business in his van. Atlas Blending company, the first incarnation of what was to become Cornell & Diehl had been a well respected, medium-sized blending company during the 1950s. Since then Amar (the company that had purchased Atlas Blending) had slowly but progressively fallen apart. By the time Amar Blending had been redubbed Cornell & Diehl (Craig's middle name and Patty's Maiden name) it had just a handful of customers and had not added a new one in many years.

Regardless, Craig and Patty Tarler (instead of retiring, following an illustrious career in communications and marketing) tirelessly set about reestablishing the company. Their fundamental belief, that still holds solidly today, was that creating high-quality, additive-free blends would ultimately reward their efforts. Clearly, it has. The Tarlers have garnered a reputation for producing outstanding blends from the highest quality tobaccos at very reasonable prices.

Indicative of this mentality, Craig Tarler eschews all additives (except various juices and liquors in his aromatics), especially glycol, an additive often used to maintain the moisture levels in the tobacco. Indeed, Mr. Tarler is so adamant about not using tainting additives that he uses only distilled water (with very tiny amounts of white vinegar to prevent mold, less than 1/10 of a percent (.0001) of a pound of tobacco, to prevent mold) to add moisture to the blend. Although many prefer Mr. Tarler's slightly drier style, some believe that his tobacco are a little too dry. He suggests that small amounts of water can be used to add to the level of moisture in the blend.

In the few years that Craig and Patty Tarler have created Cornell & Diehl tobaccos, their blends have garnered a remarkable reputation for the excellence in quality and refinement in blending.
