Why Am I Marketing Baltic Rye Bread?

by John Melngailis

I (John) am Emeritus Professor of Electrical and Computer Engineering at the University of Maryland. I could be consulting, teaching, or continuing research on nanotechnology, the technology responsible for our information age, and much more—work that I have enjoyed for many years. Instead, I am marketing Baltic rye bread.

Why? Because I believe, and I am not alone, that the critical issue facing us today is the health of our population. Persuading people to eat the super-healthy, 100% whole-grain rye sourdough bread of my homeland and of my family is my small, personal contribution to improving health. More sophisticated electronics, to which I have contributed in my long career, will not do it.  In fact, you could argue that it has contributed to our health problems.

Personal connection

My family came to the United States in December 1949 from a DP (displaced persons) camp in Germany. Just as Syrian refugees today are fleeing death and destruction, we left Latvia in October 1944 in advance of the Soviet Red army.  We were fortunate to end up in the United States, in our case, in a remote corner of Western Pennsylvania. I was warmly welcomed as a 10-year-old fourth-grader in the local one-room schoolhouse. My parents were happy to have a roof over our heads, plenty of

food available, work, good prospects for their children’s future ….

But the bread. We lived out in the countryside and the only bread we could get from the local stores was Wonder Bread or its equivalent. To us it did not feel like bread, it did not smell like bread, it did not taste like bread, and we noticed that a hungry stray dog would not eat it. As a businesswoman in Latvia, my mother had never baked bread, yet she was determined to bake dense, hundred percent whole-grain Latvian rye bread, or “rupjmaize” as we know it. It was, and is, the antithesis of Wonder Bread: no nutrients removed by refining, no false, chemically-derived, nutrients or preservatives added. Yet it naturally has a long shelf life. But where to get whole-grain rye flour? It was not to be found in any near-by stores. My mother got a bushel of rye grain from one of the local farmers, who was growing it for some purpose other than bread baking. But how can we mill the grain into flour? The father of one of my classmates had a mill on his farm for grinding corn for pig feed. He was willing to use it to mill our rye grain. I remember him first running some wheat through the mill to clean out the pig feed and then running our rye grain through the mill twice.

My mother was born in 1896 and lived on her family farm to about age 19. With the help of an old Latvian cookbook and some childhood memories she began baking and soon developed an excellent “rupjmaize.” She baked almost to the end of her life at age of 91.

After she died I found other sources of rye bread: a Lithuanian bakery in Boston where we lived (it closed), a Latvian bakery in Hartford Connecticut that would ship the bread to us (it closed), and later buying it flown in from Latvia. Ken Gabriel, a colleague in the business school at University of Maryland, where I am a professor, tasted the bread and thought it was awesome. He said “we have to market it.” So we set up a small business and for a couple of years sold “rupjmaize” at Whole Foods in the Washington DC area flown in from Latvia. When the value of the dollar weakened from $1.28/euro to $1.68/euro we had to stop. We found a bakery in Brooklyn, NY Bread, that was able to duplicate the recipe. We reorganized the company and brought in my brother Ivars, who set up our “rupjmaize” online business. We have been selling the bread largely in the New York area for 11 years. I’m not earning any money doing this—I make no salary—so why do it?


Health Crisis

We are facing a health crisis in the U.S.: obesity, diabetes, heart disease, etc. An important factor contributing to the poor health of our population is the excessive consumption of industrial, over-processed food thanks to the drive for corporate profits aided by misguided government subsidies. I am convinced that introducing our rye bread to the American diet would be helpful. It is delicious paired with traditional rich foods like smoked salmon, grilled sausage, herring, bacon and eggs, schmaltz, butter, cheese and so on. It also pairs well with healthy vegetarian foods like nut butters, avocado, radishes, hummus, cucumbers, or raw honey. To any rich food it provides the counterbalance: the fiber and body which allows the rich food to be properly digested. So fa we have had some success in gourmet stores and with consumers with Northern or Eastern European roots. Ideally, I would like to introduce the bread to the general American public. My quest may seem quixotic. I often like to say: 

Everything is backwards. This is the richest country, yet it has the world’s worst diet. The rich are skinny, the poor are obese. The good food is in the big cities, the unhealthy food is in the countryside where food is grown. And now I am marketing the most humble Latvian peasant bread in gourmet stores.

In Latvia, our rye bread or “rupjmaize” is a staple food, particularly for the less well-to-do. (Everything there is not backwards.) Hearty whole-grain bread with a long shelf life has sustained the Northern Europeans for centuries. Even today you see very few who are obese or even overweight. Diet may be a key factor.

I want the U.S., my adopted country to which I owe so much, to benefit from my experience.

Health benefits

Let me first make some nonscientific claims. Based on what I know from my own body and from what friends and family have said, whole-grain rye bread is satiating. It makes you feel full in a wholesome way. My own taste buds tell me that our rye bread is the ideal accompaniment rich foods. I would find eating a teaspoon of pure butter by itself revolting. Yet spread on a slice of rye bread it is delicious. The same can be said for other rich foods.


Scientific Studies

A fair amount of research has been done in the area of rye bread and nutrition. I have found and looked at much of the peer-reviewed literature on the subject using, for example, the Web of Science, which I often used in my own research. Then I stumbled on the following website:


This website makes all the arguments I would want to make and more, and in greater detail. It includes extensive references to much of the same literature I found. One can legitimately be skeptical of material “published” on the web. However, in this website claims are substantiated by published, peer reviewed research, and the list of universities and companies that created the website are disclosed.

One could point out that the baking companies who sponsored this website may have a vested interest in the conclusions (so do I). Still the companies make money regardless of what grain is used. Universities and research institutes are expected to be objective. Moreover, all participants have an interest in maintaining their reputation for integrity.

The Rye and Health website discusses several areas where rye is expected to have a positive impact on health including glucose and insulin metabolism, weight management, cholesterol reduction, and colorectal cancer prevention. The benefits are supported by conclusions of research papers published in peer reviewed journals.

Gluten content of food has become a concern for many Americans. Some healthcare practitioners continue to group wheat, oats, barley and rye together under the heading of “gluten grains” and to ask for elimination of the entire group on a gluten-free diet. Other practitioners now treat wheat separately from these other grains, including rye, based on recent research. Wheat is unquestionably a more common source of food reactions than any of the other “gluten grains,” including rye. Stanley Ginsberg in his book “The Rye Baker” discusses in technical detail the chemistry in the rye dough and in rye bread. The action of gluten in rye is quite different from what it is in wheat. Wheat bread depends on gluten to give it a porous structure, but the gluten hardens rather quickly causing the bread to become stale. Rye bread on the other hand does not depend on gluten to give it structure but rather on a starchy gel which remains tender long after baking and explains why rye bread stay fresh for weeks. In addition the rye kernel contains a lactic acid producing bacteria as well as wild yeast which turn simple sugars into lactic acid just as in yogurt, buttermilk and sour cream. It is this combination of factors which results in the long shelf life of rye bread and the absence of mold. A long New York Times article (“Rye Rises Again” Food Section, January 11, 2017) also states that the gluten content of rye is lower than that of wheat. A couple of friends and relatives who are gluten intolerant are nevertheless able to comfortably eat the rye bread.

In the past, diet was largely determined by availability, taste, and tradition. Nowadays a bewildering array of foods is available, tradition is diffuse and taste is manipulated chemically, and by advertising. Food claims based on scientific studies abound leading the various fads.

So it is with some skepticism that I have nevertheless cited scientific studies showing the benefits of rye bread. For my part I pay attention to my taste buds and how the food makes me feel.

The Future

Over the past nine years I have spent thousands of hours demoing rye bread in stores. Somehow doing two 4-hour, back-to-back demos in one day on my feet has been less tiring than uplifting.

My dream is that someday more people will buy our rye bread with food stamps than with American Express gold cards. 

We are far from realizing the dream. At the moment Black Rooster Food is selling Baltic rye bread in 38 stores, 3 restaurants in NYC, and one prestigious catering company in DC. Of the stores 26 are in the NYC area and 6 in Boston area, and 6 in Washington DC area.

Over the years, the United States has absorbed food traditions from all parts of the world. It takes time and it starts with the more affluent, well-traveled, and adventurous eaters. In 1966 when I returned from a year in Paris, hardly anyone knew what a baguette was. Now they are everywhere. Similarly, 50 years ago sushi in the U.S. was almost nonexistent.

Rye bread may be starting on a similar path. Recently some articles have appeared pointing to this: New York Magazine “Rye’s Rise,” Sept. 15, 2013 (it features our bread among others), The New York Times, (“Rye, A Grain With Ancient Roots, Is Rising Again” Food Section, January 10, 2017), and Serious Eats devoted an article to our endeavor

Given the density of our rye bread, it works best for openface sandwiches. Openface sandwiches are beginning to appear with increasing frequency in the food scene in New York and beyond: Dean and DeLuca, and The Great Northern Food Hall in Grand Central Terminal are serving openface sandwiches. The rapidly growing chain Le Pain Quotidien serves only openface sandwiches.

Perhaps people are beginning to appreciate the arguments I have made above for more natural and less-processed food. The simple honest taste based on freshness in Nordic cuisine is attractive and Nordic restaurants and eateries seem to be opening more and more in New York City. I can see the beginning of a trend.

There is a clear movement away from over-processed industrial foods towards more natural products. However, in many cases people are inhibited by the expense of these more wholesome and healthier foods. Thus, the less affluent tend to have a diet based on industrial, heavily advertised, heavily subsidized, poor quality foods. This is where our bread could find its place. In Northern Europe, rye bread continues to be staple food, not only for the gourmets, but especially for the less affluent. Why not here in America? Rye bread is relatively inexpensive, it's nutritious, filling, delicious, healthy, and has a naturally long shelf life. If whole grain rye sourdough bread became a staple food in our diet, I am confident the health of our population would improve.
