And RUBY Makes Four - A New Flavor and Color Join the Chocolate Family

On what may eventually come to be known as "RUBY Tuesday" - September 5, 2017 - chocolate industry giant Barry Callebaut introduced, in Shanghai, a fourth type of chocolate ... RUBY Chocolate.

A Very Brief History

We can trace the invention of dark chocolate as we know it today - eating chocolate - to England in the late 1840s. The late 1870's saw the introduction of milk chocolate, and white chocolate was brought to market in the late 1930s. These three base varieties form the Trinity of chocolate, just as Criollo, Forastero, and Trinitario form the Trinity of cacao.

What Is RUBY Chocolate?

RUBY Chocolate is made from RUBY cocoa beans. These beans are not the result of GMO experiments, nor are they a distinct variety of cocoa in any classic sense.

What Are RUBY Beans, Then?

Back in 2004, a Barry Callebaut (BC) researcher took note of an interesting phenomenon: some cocoa samples, when processed in a particular way (BC is treating this information as trade secret - much the same way Coca Cola and KFC protect their formula and recipe), turn a characteristic red color and have a pronounced red berry-forward flavor.

Nothing was done with this observation for about a decade, at which point it became the focus of research to discover what was behind the phenomenon. What was going on chemically? Was it an isolated quirk? Was it something that had commercial potential at scale?

Working with Jacobs University, it was discovered that there was a group of precursor compounds in cocoa that, when present in the correct ratio and in sufficient quantities could, when "activated" through special processing, consistently produced a product with this characteristic berry flavor and ruby color. These beans came to be called RUBY beans.

Further research may show that these precursor chemicals are naturally present in all cacaos, just not in the amounts needed to express the ruby flavor and color. Because one of the quality standards for cocoa is '80% well fermented,' the phenomenon was not noticed before because no one was ever looking closely - and few companies have the scale and resources to take advantage of this quirk.

In addition to special processing techniques, BC developed special supply chain tools to help them identify candidate cacaos around the world. From a sourcing perspective, one challenge is to aggregate these cacaos, separating them from beans without the RUBY properties. When sufficient quantities of the RUBY beans are processed (using proprietary techniques) in the absence of beans without the RUBY properties, the resulting chocolate has a distinctive red berry flavor profile and a reddish hue that correlates with the flavor.

So, is it REALLY Chocolate? Really?

In a word: absolutely yes. The RUBY Chocolate debuted on RUBY Tuesday meets all the criteria for milk [Note - I am fact checking this assertion - it is possible I misheard and it is more correctly a white] chocolate set forth in CFR 21.163. I did not personally see the ingredients list, but one of the chefs whose work was showcased at the launch said that she saw the list and confirmed that there were no added flavors or colors or anything not found in a real chocolate.

In the future, we are likely to see versions of RUBY Chocolate that conform to the standards of identity for sweet chocolate, which covers what is commonly referred to as dark chocolate - a term that is not appropriate when applied to RUBY.

Okay, so What Does RUBY Smell and Taste Like?

There is little to none of the characteristic cocoa flavor that is associated with chocolate.

I wonder how much of that is because of the color? At first reveal, RUBY does not look like any other chocolate you've had. How does that visual surprise affect other sensory perception?

The snap is what you'd expect from a well-tempered milk chocolate.

The aroma is faint but distinctly fruity, with none of the sweetness that is characteristic of most white chocolates and many milk chocolates. There is no detectable vanilla on the nose.

Likewise, on the tongue, there is no distinct cocoa/chocolate taste. instead, the taste is bright and fruity, predominantly and distinctly fresh red berries. I wonder how much, if any, of the red berry flavors found in some dark chocolates find their source in the RUBY precursor chemicals?

The texture is very much like a very fine milk chocolate verging on white chocolate when it comes to melt and mouthfeel - rich and buttery.

The finish is quite short, and this may contribute to some of its appeal - it's a very snackable chocolate and I can see how it would be very easy to finish an entire bar without really trying or being aware of it.

These factors may lead some people to belittle RUBY Chocolate as not being "real" chocolate, just as many people think that white chocolate isn't really chocolate.

It is really chocolate - and I believe that the flavor and color will be highly appealing to many - not only consumers but to pastry chefs and confectioners.

From a confectionery application perspective, RUBY works exactly as you'd expect a chocolate to work. You can deposit, shell mold, and enrobe with it. Make ganache and engross (pan) with it, color and spray it with an airbrush and flock with a paint gun. It can also be aerated. I did not see/taste any baked items with RUBY and so I can't comment on its applications in baking.

But it is also true that the flavor and color could be knocked off using flavoring and colorants in white chocolate. However, those would need to be disclosed on an ingredients list and BC is confident that their target markets are going to preferentially seek out the "all-natural" product, and their market research suggests consumers are going to be willing to pay a significant premium for "real RUBY" Chocolate.

Who Can Use RUBY?

RUBY cocoa beans are not going to be made available by BC - RUBY will only be available in couverture form. So, this is not an innovation that is going to be easily embraced by the small maker (craft) market. In fact, I predict that there will be a lot of haters who will bash RUBY and try to claim that it is not real or that is fake or rubbish or worse - GMO. But they are wrong.

Practically speaking, RUBY is not likely to be widely available until early 2019. This is not because of supply issues, but it represents the reality of introducing not just a new product but creating a new product category. (Something I very aware of through my work with Solbeso.) RUBY might eventually even spawn its own category in awards programs.

Interestingly, and very importantly, BC has not trademarked RUBY. Quite the opposite - they are deliberately "genericizing" it. They want the word RUBY to become the next Kleenex, Band-Aid, or Xerox; to take its place as the fourth member of this set: dark, milk, white, RUBY.

Why is This Important?

Real innovation in chocolate is hard to come by and RUBY is an example of real innovation, in my opinion. The project identified a characteristic inherent in cacao and, through extensive research learned how to harness this chemistry to create an entirely new category of chocolate.

There is a lot of hard work ahead to make the product successful in the market. BC is not a B-to-C company, and it has to rely on its B-to-B customers to deliver its messaging to the market.

RUBY is not going to be for everyone. And that's okay. But, for those who can think way outside any boxes, RUBY represents a once-in-a-generation (if not lifetime) opportunity.

Hi Clay, not very clear from your writing. Do you know or did they not disclose whether it is not just purple cacao butter, that there is 100 % cacao mass at the base. Also tend to agree with chocoladeverkopers. If they really don't want to patent and want this to flourish, they would reveal the R&D. Maybe their patent application was denied? The application is really not that evident either. Perhaps this is why they are testing the market, and hoping a new market, such as China, that doesn't have already a preconceived notion of chocolate would embrace it.

@burksr - there was no mention of any special genetics other than this is NOT a GMO bean. There was no mention of special post-harvest (and I asked this directly). The flavor and color are directly tied to each other.

@chocoladeverkopers - No, BC don't have to be open at all. Coca Cola is not open and they are part of the "cola" family of carbonated drinks. We know a lot about how soft drinks are made but not the specifics of the recipe. They would need to disclose aspects of the recipe if they want to get a specific standard of identity in CFR 21.163, but they would not have to disclose processes. What is part of the psychology of the product is that the flavor and the color are correlated, the red color is consistent with the red berry flavor. It may or may not be possible to use the techniques to create chocolates with other colors, but a yellow chocolate would have to taste of a yellow fruit (banana, pineapple, mango, etc) for it to work. How do we know this? Think green and blue ketchup. They were failed novelties because the color and flavors did not match expectations ... even though there are green tomatoes.

@sikendrick-aogfoods - BC are keeping the process tightly under wraps for now. You know what I know - or knew enough to ask about. There have been some other articles with new details and I am following them up with BC directly to make sure that I am presenting the story as correctly and completely as I can.

@Eri - There may be a patent on part of the process. I have asked BC if the patent referenced is related to this project - the timing on it may not be right given how long it takes to get patents granted. Other articles are talking about adding "powder extracts" to white chocolate and I have asked BC to let me know if Ruby conforms to a milk chocolate or white chocolate standard of identity.

From everything I was told, there was extensive consumer research done on Ruby. You are right in that China has fewer preconceptions about what chocolate is (and is not) and so will be very accepting of it. The same thing is true of younger people eager for new experiences and who are more open to the idea of a ruby chocolate.


We've actually known how to make reddish chocolate for quite some time (should it ever become public knowledge, there will be a collective groan of 'well that makes sense' uttered) - Callebaut is simply the first to market it as such (and that - they are quite good at). I won't get into the specifics of how it's being done (other than to say it's heavily process dependent) - but there likely need to be some labelling elements that are addressed before this is released into the wild in markets that have standards of identity (or the standards will need to be updated).

As a non-chocolate maker and non-industry person, I'm looking forward to Ruby, although I'll probably see it as more of a different animal, since it seems that it will lack any discernible cocoa flavor. I'd like to know more about the flavanol compound content though. As someone who does know a little something about GMOs, it most certainly is NOT a GMO. There are actually only 9 GMO crops: corn, soybeans, alfalfa, cotton, papaya, sugar beets, potatoes, canola, and summer squash. Supposedly, apples will be in the market this Fall. No GMO cocoa, Ruby or otherwise.

@conversation - - I have confirmation that Ruby beans are non-GMO (as Keith says there is NO GMO cocoa, but some people persist in spreading that rumor, playing/preying on emotion), just regular beans that have a specific chemical profile. Callebaut calls the beans that have this chemical profile Ruby beans. I have also confirmed that no petrochemicals are used in processing, and that the acid used to preserve the color during fermentation is citric acid.

From a labeling perspective, Ruby is classified as a couverture chocolate in the EU, but does not conform to CFR 21.163 because the residual level of citric acid is too high. Until a standard of identity can be created, temporary marketing permits will be used. Temporary marketing permits were used for white chocolate before the SOI was codified.

@Sebastian - Welcome to TheChocolateLife on The Maven, and I am very happy to have your voice here.

Right. I am not surprised that the ability to make a reddish chocolate has been around for a while - but that BC were the first to run with it. I, for one, heard that collective groan as well as a lot of pushback from members of the small maker chocolate community who are mistrustful of highly processed cacao products.

I covered a lot of my feelings in my update from a couple of days ago. If you get a chance to read that I'd appreciate your reactions.
