SAN ANTONIO -

The potato is one of the most popular foods, not only in America, but across the globe. 

The spud business is so big it needs its own potato expo. 

The Henry B. Gonzales Convention Center is hosting the sixth annual potato convention.

“We needed some way to get interest and make people aware of what is available,” said Colorado Potato Growers Manager Preston Stanley.

There are about 1,700 conventioneers in town for three days, along with more than 160 exhibitors demonstrating products that will take care of potatoes from planting and harvesting to packaging to selling.

The potato industry is big in 12 states, mostly in the Midwest. Stanley is from the fifth largest spud producer in the country.

“Colorado has some of the better potatoes, due to the high altitude advantage that we have," Stanley said.

The industry is still producing the popular Brown Russet potatoes, but it is also moving toward more of a specialized potato for the consumer.

“They are looking for something unique and special," Stanley said.

The potato growers are delivering unique breeds, like the Purple Majesty, the yellow Midnight Moon and the pink Mountain Rose.

"People are looking for color on their plates, and we can just about put any kind of color and anything you want,” Stanley said.

Something else people want is nutritional food and potatoes can provide that as well.

“If you look at the traditional content of a potato, it is one of the best foods that you can eat,” said Walter Stevenson, who represents Wisconsin growers.

“The potato doesn’t deserve the rap it gets,” said Stanley. "It's healthy, vibrant, full of minerals, vitamins and potassium.”

Stanley doesn’t hesitate to point out the flavor either.

“The taste buds just pop and go wild. The saliva starts flowing, I tell you, they are so good," Stanley said.
