| FEATURES – This week Tea Biz travels to Switzerland to learn from ETH Zürich physicist Caroline Giacomin the physics of that colorful sheen that rises to the surface of black tea. Is tea scum just that or a revealing indication of goodness in the cup? … and then we travel to New Delhi, India where the Rainforest Alliance’s Madhuri Nanda reveals how practitioners of RA’s sustainable farming methods are evolving toward broader, more holistic ecosystems in Part 2 of our series on Regenerative Agriculture.

The Physics of Black Tea Film

Have you ever noticed a colorful sheen on the surface of your tea? It appears to break like ice floes in the arctic as the tea cools. Researchers once thought tea film was due to waxy substances contained in tea leaves released during steeping. That is not the case. The delicate film is an interfacial interaction of air, tea polyphenols, and calcium carbonate ions in water. It does not form on white, yellow, green, or lightly processed oolong teas, only black tea. In many parts of the world, soft water prevents the film from forming. Is tea film a fleeting glimmer of color to enjoy or an ugly scum to quickly dissipate with a squeeze of lemon. Caroline Giacomin, Ph.D, a physicist at ETH Zürich, Switzerland joins us to explain the physics of tea film from a study she and colleague Peter Fischer recently published in the Physics of Fluids. 

Regenerative Agriculture: A Holistic Approach

The Rainforest Alliance's Madhuri Nanda explains that while sustainable farming ensures that agricultural practices do not negatively impact and degrade the environmental, social, and economic aspects of the surrounding ecosystem ̶ the focus shifts in regenerative agriculture toward adopting a broader holistic approach that enhances biodiversity and improves soil health through increased microbial activities that build resilient systems capable of withstanding adverse climatic scenarios."

...the past four years, according to theTea Board of India, Teaboard Dana shows that only twenty seven million kiloshas been re exported during this time, making it likely that forty threemillion he loaves were sold domestically exempt from import dutiesand in direct competition with Darsan producers. Teas exported from India pay a fortyper cent tariff to enter Nepal, but NAPOLE pays no tariffs to ship tea toIndia due to terms of the South Asian Free Trade Agreement.

Switzerland joins us toexplain the physics of t film from a study she and colleague Peter Fisher,recently published in the physics of fluids. Thank you so very much for coming onthe program. This topic is fascinating and I see that it's already gettingsome attention. Let's first talk about what made you curious about that scum.I was working somewhere where the water was particularly hard, and one of mycolleagues said during our like afternoon, tea time that he doesn'tdrink tea anymore because he doesn't like the stuff. That is on top of ithe's from Taiwan, and he had never seen that come before or the film before,and I had never really thought much of it. Sometimes it was there. Sometimes Ihaven't been there, so I went home. I looked up. How to get rid of the film,for him turns that you can have lemon juice. That's what every one on message,boards and stuff will say, not a particularly scientific answer, but youknow obviously a traditional answers. My colleague drinks creamy, so lemonjuice is not really something Manala out of the green hat that wasn'thelpful to him, but I didn't really worry much about that at the time. Itwasn't really in my realm of research, but I came to start my phd and in ourgroup here we have a document. My professor is made up of interestingideas he's had over the years and we study interfaces in this group and onhis list of interesting ideas. was she interfaces and, I said, Hey, I thinkthat's an interesting topic and I've looked into it before it, a lovelystory, and I ampla you for thinking. Broadly,you know in science it isn't just narrow routes. It's that wonderfulopportunity to appreciate all the world around us. So how did you go about determiningwhat the film was caused by so there's a researcher from England inthe N, in the A toute at fourteen part series on t and about six or seven ofthose were about the t film, so I kind of followed a little bit in hisfootstep as to what he did that he was studying the components of the tea filmand since we work with Inter facial strength, I was going to be doing thestrength of the fell, we're studying types of tea. You know lemon juice,adding sugar, adding milk ETCA, but now we're studying the physics of itinstead of the chemistry of it. So I based at least the choice of Adam- waskind of based off in his research reales. The study of weird fluids, ifyou think about like boo black, which is the corn starch and water mixturethat kids like to play with a or the fling or you think, about, measuringhow shampoo or platen bolden plastic flow. That's how Rologe and an interfacial just means we're dealing with the reality at the surface between twophases. In our case, we're getting the popas of liquid tea and air, and sointervital reality takes a metal device and we put it exactly in contact withthe surface and then we carefully control the movement of that metaldevice. There's a motive, that's controlling and movement, and also acensor that is detecting exactly how much force the motor is having to applyto make the movement happen, and so that can tell us how riddle or howelastic the film is and exactly how...

...much force we need to apply to breakthe film, so the thickness, isn't. The critical factor is that the scacely,the resistance to movement of the Metal Plate? How do you describe the films interms of its physical characteristics, as opposed to its chemical componentsand our feel we use the phrase Moduli, which can be the elastic and the lot orviscus Moduli, so the elastic moduli determines the elasticity of it. Haveyou know if you move in to film a tiny bit, can it can it reform itself backinto original position? So you know the law made is kind of going to give youthe Brittleness of the film and the Elastic Modulus is kind of theflexibility of a stretching on. So, from a practical point of view, you'vedescribed the physics the chemistry was previously described as Ti Pali Pino'sbonding with calcium carbonate, ions at the surface, to create a colorful sheen.If I'm making a cup of tea, should I be anti scum? Should I dissolve this cometo get rid of it, or should I appreciate it for what it is and notworry? Is Peace come and indication that I need to do something with mywater based on your research? What practical guidelines do you suggest onhow to make better tea or a better enjoy tea? He it depends on what youview is best for TV, the film, especially when you don't add milk, thefilm is quite beautiful and a scientist describing peace gun is beautiful, butthe when you add milk to piece on is quite often not particularly visuallypleasing and it kind of looks through those. Two films are actually made avery different opponent, which is by in my research we weren't able to measurethe resistance of the milk film, because there's too much oil and factin it for to be measured by our device, it cause too much slipping essentially,so those two films are different, so in if you're making to where you wouldlike to have milk in it, I would suggest you make that tea with what itit's gone, either through a filter or if you're living in a place where thewater isn't particularly hard anyways, but it shouldn't really matter too muchyou're not going to have much of a film anyway. Now that I know what it's whatit is, I like see it. If you really don't like the film take, you knowblack tea with lemon and you won't be able to see it. Then there will stillbe technically a physically strengthened film there, but you won'tbe able to see it. That's all that really matters at that point. Itdoesn't have much of an effect in a favor. The rainforest alliances, Mondrian deexplains that, while sustainable farming ensures that agriculturalpractices do not negatively impact and degrade the environmental, social andeconomic aspects of the surrounding echo system, the focus shifts andregenerative agriculture towards adopting a broader holistic approachthat enhances by diversity and improves soil health through increased microbialactivities that build resilient systems capable of withstanding adverseclimatic scenarios. Is there an accepted definition ofregenerative agriculture? No, I wouldn't say there is a declinedefinition as we eedete say something new that was going around on th s bythe Reval Institute till you know, we lost the definition. It has pight againinto thousand and fifteen that in India, if theres, something which is in gradein our creational practices. So it's definitely not new concept,which is there. It draws from the principles of agroecology and holisticecosystem management, looking both and...

...to form and landscape Lebel at at ranfor a alliance. So we really believe this is a part of a broader frameofmind.It's an umbrella part, so a rain persean standard really looks atseveral other principles of which reach Aratov agriculture principles are onepart of it, so it includes, for example, in addition to the sustainabilitydimensions. It looks a Rasal living conditioners, child labor for Labor etCE and an integrated system management approach very aims to increase by ourdiversity, and you have to keep that in mind that improving anything thatimproves by diversity then also helps as pike. Climate Change, which issomething which is a very intricate, engage and well established. So O bestpractices and regenerative agriculture differ from sustainable farming.Sustainable farming definitely ensures that agriculture practices are notnegatively, impacting and degrading the environment, social and economicaspects of the surrounding persistence, but I would say it is still maintainingthe status code. So, whenever you are doing, you are not further depletingwhen we talk of Rechart Ad Pulsion, I would think it is more of a naturalprogression where you start reach and rating your ecosystem, where you tryand see how you can increase, for example, my Po Yal activities and willresilient systems that can withstand the adverse climatic scenarios which weare facing. Cuneta a lot of times. Eaten ready is a more holistic approachand sustainable forming is something which is still at. You know at thestate is for maintaining, so it's still good, but the way forward should belooking at the region, rated agriculture or Pete. Our standardactually incorporates many of the principles of each Anato. articulturalsuch as soil has management interviewed best management. Where is a lot ofpocus on biodiversity, conservation, Egro, forestry and looking at the youknow in its entirety the climate, smart practices? What are the most pressingchallenges facing the Tea Industry Harry has been working in the teamdusty for a very long time. What we see currently specifically in India, ifthat also Robelle, we see the t industry- is facing significantchallenges: Climate Change Again, which is directly impacting keep production.They are facing increased best intestation, which are needing tosignificant crop loss. You know you see that there is an addition to thatsupply chain. The destructions, which are for the last two years, effectingbeing affected. Outo pandemic, Terios absentis m on the farms, the Shota ofLabor increase, cost of production, unpalace market conditions also areleading to you know. You know, challenges and their profit. Thescenario, so their proper class sheets balances are really difficult for themto maintain and when, on top of it, you ask them for sustainable practices. Nowthat's a difficult challenge, because there's a post of sustainability, whichis really difficult to maintain when your entire business is going downbecause of the prevailing climate and the surrounding environment situationsand the operational issues on ground. Boki players in the tea industry arealready moving towards finding seditions to handle these challenges.They are a diversifying and they are looking at moving away from monocultureto see how they can improve their own revenues, whether it is spices, forexample, we see a lot of temare grown in those areas in it. If you go backand look at a son, so those diversifications are happening withinthe deal lustry so that they can also diversify their income sources. So that's a natural progression whichwe see is happening and they have already innovated and intestine.Farming is now moving to US divers in...

...the proven, I would say, the need forshape trees due to the increasing climate conditions than what they feelis, which is an Igoo stry model by common in the Dadus, is also bringing aship towards divers and moving away from monoculture practices, and that'sreally improving the soil hill in the long run.
