In 1902, David Peri’s grandfather emigrated from Italy and started a small farm in Lockwood, Nevada. The original Peri family farm passed from David’s grandfather to David’s father and uncle, but the third generation of Peri’s took different paths. While his siblings pursued other interests, David knew from a very early age that farming was his singular passion. Immediately after graduating high school, he followed his heart and built his own farming operation further out in Yerington, Nevada – Peri & Sons Farms®.

While still in his early 20s, David shrewdly started buying acreage, and began focusing his efforts on growing onions—a product that he believed would increase in demand in the coming years. What started in a 100-acre field over 30 years ago is today a multi-million dollar business and one of the world’s largest onion operations, with over 7,500 acres in production.

Peri & Sons Farms is now the largest private employer in Lyon County, currently supporting over 220 year round full-time positions, and a seasonal work force of over 1,400 full-time employees. The company’s direct and indirect impact on the economy in Northern Nevada now exceeds $75 million.


And now, let’s dive into the questions!

When did Peri & Sons Farms first start growing sweet onions?

In 1998, Peri & Sons Farms started developing a truly sweet onion cultivar because our retail and wholesale customers wanted us to offer a sweet onion for the late summer/fall and holiday season. No other domestic onion filled that need fully at the time. So that’s what we set out to do. After several thousand hours of research (with help from some farm and seed professionals) our Sweetie Sweet® entered the market in 2003. Our first crop was grown on 40 acres and yielded about 1.6 million pounds. As the demand for sweet onions continued to grow, so did our acreage.  We now sell about 35 million pounds of sweet onions annually and we expect more growth to come.

Why does the Sweetie Sweet season only last five months?

little lisa sweetie faceTrue sweet onions are different from typical Spanish-yellow onions but, unfortunately for consumers, not all onions sold as “sweet onions” truly are. A true sweet onion has a more delicate outer skin, contains less pyruvic acid (the heat factor) and has more moisture within the tissue than a typical yellow onion. Because of this, sweet onions are softer, more temperamental and more susceptible to damage and other natural factors that will break the onion down with decay faster than it’s more hardy and dense yellow cousin.

We work hard and plan our crop carefully so that we grow just enough Sweetie Sweet onions to cover demand and have them available within the time frame that we know our Sweetie Sweet will naturally retain optimal freshness.

Do your Sweetie Sweets start from bulbs or seeds?

sweetie sweets in boxAt Peri & Sons Farms, we produce and control our own seed supply, so we are able to maintain optimal quality and integrity, which sets our sweet onions apart. During each growing season we analyze every field, using an advanced GPS mapping system, to target the best quality bulbs for our proprietary seed-production process. These special bulbs are nurtured and monitored until they are ready to produce our Sweetie seed. We make the extra effort to grow our own seed to ensure our Sweetie Sweet onions have a consistent flavor and quality profile year-after-year.

How do you keep Sweetie Sweets looking so nice?

One of the things we do to ensure our Sweetie Sweet onions maintain the highest quality possible is that we still take the time, and incur the extra labor costs, to hand-harvest them in the field. Nowadays most onions are mechanically harvested using large machines. Unfortunately, these machines have a tendency to nick and bruise the onions damaging the appearance, but more importantly, damaging the skin, which allows bacteria to enter. Nicks and bruises compromise the onion’s quality and speeds up the decay process.

How do I select a good sweet onion?

sweetie sweet onionsWhen looking for a perfect sweet onion choose one that has a tissue–thin, shiny skin and a firm, tight, dry neck. Sweet onions have a marble coloring of light yellow, brown and green. Regular yellow onions in comparison will have thicker skins that are usually a shiny copper-brown color all over. Avoid onions that have soft spots or surface bruises.

Although flat-shaped onions have generally been the most widely advertised “sweet” onion, shape itself is not an indicator of sweetness. We urge produce-sellers and consumer alike to examine the texture and color of the skin and to ask whether the sweet onions they are buying are guaranteed to be sweet. Have they been tested? Whether it’s large, small, flat or round, in the end, taste is what matters. A sweet onion is expected to taste sweet with no mouth burn. If you are unsure, make sure to ask the produce team so you know you are getting the true sweet onions you are paying extra for.

How do we know your Sweetie Sweet onions are as sweet as you say?

Even though we start with home-grown seed, weather and other factors such as farming technique, field management and geography also come into play. If not properly nurtured and monitored a crop can become stressed which could then result in the onions not having the proper sweet composition at harvest.

At Peri & Sons, we have a highly-trained farm and agronomist team dedicated to monitoring and testing our Sweetie Sweet onion crop throughout the growing season. Years of experience growing our Sweetie Sweet helps to minimize risk, but just to make sure we put our onions through the SweeTEST process

Our SweeTEST process involves testing fresh onions, which have been selected across the crop using GPS tracking, at a highly-respected, third-party lab with over 30 years of onion-pungency research experience. The process tests our onions for brix, sugars and pyruvic acid and additionally, but we go even further and also test for flavonoids, lachrymatory factors and thiosulfate ─ things that impact the overall flavor. Only onions that meet the SweeTEST criteria for sweetness and for flavor qualify as Sweetie Sweets.

What’s are some of the best uses or recipes for sweet onions?

In my opinion you get the fullest flavor experience when you eat a good sweet onion raw or minimally grilled. A nice thick slice on a burger or sandwich adds a wonderful burst of flavor and crunch. Simply mouthwatering. You can thread them on a kabob or stuff-and-bake them too. Sweetie Sweets caramelize really well, because of their high sugar content, but make sure not to stir them too vigorously because they are delicate and watch them closely so they do not overcook or burn.


Well, that concludes the 10th edition of our Ask the Produce Expert series!
