  • Potato planting begins in our fertile fields in the Pennsylvania Dutch region.
  • Center-pivot irrigation helps grow healthy, nutritious Masser spuds!
  • Green and healthy: Potato plants sprouting and growing in the fields.
  • The potatoes at harvest time.
  • A potato harvester brings the potatoes to the surface.
  • Potatoes arrive at the plant on a bulk-loaded truck.
  • The truck is unloaded upon arrival to minimize damage to the potatoes.
  • The potatoes travel through a water flume to wash off the field soil.
  • The potatoes are pressure-washed to remove any remaining field soil.
  • The potatoes are optically scanned for defects such as greening or hollow-heart.
  • A random sampling of potatoes is taken and inspected to ensure quality.
  • Potato sizing is an electronic process at Sterman Masser.
  • Sorting
  • The potatoes are subject to their first visual grading.
  • The potatoes are weighed using a computerized system.
  • The sorted potatoes are stored in temperature and humidity controlled bins where they are cooled and dried before packaging to increase shelf life.
  • The pre-weighed potatoes are automatically bagged and sealed. The bagged potatoes are checked for correct weight and then palletized for shipment.
  • Potatoes are also packaged for retail sale.
  • From plant to plate, our potatoes deliver a delicious difference you can see and taste!

Agricultural, quality, food safety, and processing best practices are implemented every step of the way from our farms to your table in order to insure that we deliver a delicious difference you can see and taste.

Growing Quality In

  • The difference in our potatoes starts with our selection of farmlands in the rich Pennsylvania Dutch Hegins and Lykens Valleys. The rolling hills and red shale soil of these valleys provide a unique, well-drained farmland composition that contributes to the deliciously unique taste and rich, creamy texture of the high quality potatoes grown on Masser farms.
  • To optimize flavor and quality, we plant specific potato varieties that we know grow best in our soils and our climate.
  • We rotate crops every 3 years to insure sustainable, healthy soil both now and in the future
  • We vine kill before harvest to set the potato skin; this protects the flesh throughout the harvest and packing process and insures our potatoes look as good as they taste. 

Harvesting, Storage, Washing, and Packaging Best Practices that Protect Quality, Maximize Freshness, and Extend Shelf Life

  • Air-glide harvesters gently lift the potatoes from the ground, separate them from their stems and surrounding soil/rocks, and gently place them into trucks for delivery to either storage or the packing shed.
  • Potatoes headed for storage are treated with a natural clove-based sprout inhibitor, cooled to maximize freshness, and placed in our climate-controlled storage bins, which can hold up to 17,500 tons of potatoes.
  • Our potatoes are packed-to-order in our 160,000 square foot state of the art facility, moving from storage or directly from the field through multiple wash stations, including a final anti-microbial rinse to prevent bacteria growth.
  • Washed potatoes go through multiple quality and sizing inspections, including photographic grading, sizing, and hollow-heart detection, on-site USDA inspection, and visual inspection by trained associates—all to insure consistent size, shape and quality in the final package.
  • The sized and graded potatoes are cooled and dried prior to being packaged in their final unit of sale, which prevents moisture build-up in the package. Clean, fresh, dry potatoes in the package means longer shelf life and greater product satisfaction when served. This also allows us to pack-to-order and provide same or next day delivery to our customers.
  • Our 5 packaging lines accommodate all pack sizes and configurations and include a "clean room" environment where we package our microwave and grill-ready products to insure consistent quality, safety, and performance at home.

A "Home" for Potatoes that Don't Quite Meet Your Expectations

Our customers have high standards and we strive to meet or exceed them everyday. Potatoes that fall short of customer specifications are shipped to our sister company, Keystone Potato Products, LLC, for use in fresh cut fries, potato flakes, and potato flour destined for foodservice, ingredient and commercial uses. That way we delight all our customers while utilizing the entire crop and minimizing food waste.


Food Safety

Safety, including Food Safety, is a Masser Core Value and the cornerstone of the Sterman Masser Corporate Responsibility platform. Our best practices to insure that the potatoes we bring to market are safe for consumers begin with our soils and seeds and extend across the entire supply chain to the final product sold in retail outlets or in restaurants.
