All over the world, the popularity of veganism is growing. Few countries, however, are embracing the trend as enthusiastically as the UK. In 2014, there were 150,000 (0.25% of the population) vegans in the UK. In 2019, there were 600,000 (1.21% of the population). In a period of five years, the number of vegans in the UK quadrupled, and almost a quarter of new products launched in the UK that year were labelled as vegan. Consumer research in 2021 showed that 15% of Brits had completely cut out dairy products from their diets, and another 42% had reduced their dairy intake. A 2022 survey of UK plant-based food trends revealed that 48% of adults in the UK are using plant-based milk alternatives, and 58% are using plant-based meat alternatives. Almost half of those who took part in the survey expressed an intent to reduce their intake of animal products. There are four main philosophical reasons for adopting a plant-based diet: Religion Health Animal rights Sustainability Religion India has the lowest rate of meat consumption in the world. This tendency towards a plant-based diet is connected to ahimsa – the ideology of non-violence – which forms the basis of India’s main religions: Hinduism, Buddhism, and Jainism. There are approximately 1.6 billion Hindus in the world, with about 1.1 billion living in India … May all beings look at me with a friendly eye, may I do likewise, and may we look at each other with the eyes of a friend. Yajurveda (a religious text) India is home to around 8.4 million of the world’s 507 million Buddhists … All living things fear being beaten with clubs. All living things fear being put to death. Putting oneself in the place of the other, let no-one kill nor cause another to kill. Dhammapada (Buddhist scripture) About 4.5 million people in India practise Jainism … There is no virtue of spirit greater than reverence for life. Mahavira (24th Tirthankara) Followers of these three religions represent approximately 81.5% of India’s total population. Although Buddhism, Hinduism, and Jainism don’t preclude meat consumption, the philosophy of ahimsa does influence people’s choices. However, the influence is more towards vegetarianism than veganism. Health (dietary veganism) Animal-food diets are associated with higher cardiovascular morbidity. High intake of plant-based foods, on the other hand, reduces the risk of heart disease. Animal foods – meat, milk, eggs, and their derivatives – contain saturated fats. Eating a lot of these foods can lead to high cholesterol levels, which increase the risk of stroke and heart disease. Animal foods contain very little fibre, whereas vegetables and grains are good sources of fibre. A fibre-rich diet helps keep cholesterol levels low. Meat has been categorised by the World Health Organisation as carcinogenic. A plant-based diet reduces the risk of cancer. Animal rights (abolitionist veganism) Abolitionist veganism is a philosophy based on the right of all sentient beings not to be treated as property or resources. The word vegan was coined in 1944 by a leading campaigner for abolitionism, Donald Watson. Abolitionist veganism objects to animal welfare movements that endorse humane treatment of sentient property, because the concept leads to public complacence and general acceptability of animal exploitation. Abolitionist vegans also stand against using dietary health as an incentive for veganism, as this motive of self-interest obscures the point of abolitionism. Sustainability (environmental veganism) Animal farming contributes to global warming and threatens biodiversity. Approximately 5 billion hectares (38%) of the world’s land surface is used for agriculture. Two thirds of this land is grazing pasture for livestock, and the rest is cropland. Roughly one third of the cropland is used to grow feed for livestock. Forests are destroyed to make space for farmland. Reduced foliage means reduced CO2 absorption, causing atmospheric carbon dioxide levels to rise. Deforestation leads to reduced biodiversity – another threat to the world’s ecosystems. Since the beginning of the Industrial Revolution, the concentration of atmospheric methane has more than doubled. Methane is a by-product of enteric fermentation, the organic decomposition by microorganisms (methanogens) in the digestive systems of ruminants. At present there are more than 264 million dairy cows worldwide, all emitting methane gas. Reduced demand for animal-based foods will lead to reduced production. Businesses all over the world are working together to bring about cultural and economic changes that will help us achieve net zero by 2050. KOJO, in Devonshire Square, London, is one of those businesses. Specialising in 100% plant-based juices, shakes, and baked goods. KOJO’s sustainability agenda goes beyond veganism. The brand has joined City-to-Sea’s Refill Revolution and is working towards eliminating single-use plastics by offering free chilled and ambient drinking water to customers from two self-service Aqua Alto taps.

In the UK, we consume approximately 95 million cups of coffee and 100 million cups of tea per day. We all have our idiosyncrasies when it comes to preparing our favourite brew, and we all believe, deep down, that nobody really knows as well as we do how to make the perfect cuppa. But when it comes to water temperature, there might, possibly, be room for improvement … Optimum water temperature for tea It’s generally acknowledged, among professional tea manufacturers, that you should not pour boiling water onto tea. (Many of us, of course, do just that.) How hot, then, should the water be? The optimum water temperature varies according to the type of tea you’re making. And the type of tea depends on the extent to which the tea leaves have been oxidised. Oxidation All teas are the dried leaves of Camellia sinensis. The difference between white, yellow, green, oolong, and black tea lies in the degree of oxidation. Green tea, for example, is hardly oxidised at all, while black tea is almost fully oxidised. Like many plant species, Camellia sinensis contains polyphenols – a group of organic compounds that includes catechins (deterrent to predators) and tannins (regulation of the plant’s growth and ripening). Through the process of oxidation – catalysed by polyphenol oxidase, an enzyme that occurs naturally in the tea plant – catechins are converted to other types of polyphenols called theaflavins and thearubigins. These chemical compounds give black tea its colour, comparable to the browning of apple flesh, which oxidises when exposed to air.   Oxidation (loss of an electron) is one half of a redox reaction. The other half of the reaction (the gaining of an electron) is reduction. In the case of tea, the oxidising agent – i.e. the chemical that’s being reduced – is oxygen. Although the term “oxidation” comes from “oxygen”, a redox reaction doesn’t always involve oxygen. Green tea is an excellent antioxidant because the catechins in the tea are available for oxidation in the body. By donating an electron to an unstable chemical (free radical), catechins can interrupt the chain redox reaction that’s associated with ageing. How hot should the water be for a cup of tea? Water that’s too hot will scald the tealeaves, giving the tea a bitter taste. The greater the extent of oxidation, though, the better the tea can withstand high temperatures. If the water’s too cool, the tea’s flavours won’t fully infuse the water. So, here’s a rough guide to the optimum water temperature for the various types of tea: Black tea (intense oxidation): 95°C Oolong tea (partial oxidation): 85°C Yellow tea (partial, slow oxidation): 80°C Green tea & white tea (minimal oxidation): 80°C Optimum water temperature for coffee There are approximately 120 species in the genus Coffea, but only a few of these species are cultivated for their caffeine-rich seeds, which are roasted, ground, and infused in hot water to produce one of our favourite drinks. Two species account for roughly 99% of the world’s cultivated coffee. Coffea canephora is best known as robusta, which is the name of one of the two C canephora varieties. Coffea arabica is a hybrid of C canephore and C eugenioides. There are several ways of brewing coffee: Espresso is a brew of coffee made by forcing a small amount of hot water, at high pressure, through finely ground coffee. Containing a lot of the coffee’s oily solids, espresso is full-bodied and flavoursome. Espresso can be consumed as it is or topped up with hot water or milk. Filter coffee is brewed slowly. Hot water drips through the coffee grinds, and much of the coffee’s oils are lost to the paper filter. Many people prefer the plainer taste of filter coffee. French-press coffee is steeped in hot water and then filtered by a metal filter which lets through the oily solids. Like espresso, it has a full-bodied flavour. Freeze-dried (instant) coffee is dissolved in hot water. There are three main variables in coffee brewing: 1. time; 2. grind; 3. temperature. Here, we’re concerned with temperature. Water that’s too cool will fail to extract the coffee’s flavours, whereas water that’s too hot will over-extract, producing a bitter brew. The optimum temperature for coffee is 95°C. Coffee and tea both have a PH of approximately 5. This slight acidity is a major feature of their flavour profiles. UK government regulations stipulate that mains water has a PH value of between 6.5 and 9.5, so in many cases, our water is slightly alkaline. The alkalinity of mains water will lower the overall PH of coffee and tea. Pure water, however, has a neutral PH of 7, so it allows the mildly acidic flavour of tea and coffee to be expressed. Aqua illi and Aqua Alto taps dispense pure water at the optimum temperature for a perfect cup of tea or coffee.  If you’d like to know more about Aqua Libra Co water dispensers, download our products brochure, or contact us by phone on 0800 080 6696 or by email at [email protected].

In its 2020 annual report, Zenith Global – world-leading consultants to the food and drink industry – revealed that UK water-dispenser sales had increased for the seventh consecutive year. At the end of 2019, there were 870,600 units installed in the UK – an increase of more than 100,000 since December 2014. The report shows that 40% (348,240) of the UK’s water dispensers are bottle-fed units, and 60% (522,360) are mains fed. Of the mains-fed units, just under 37% (191,532) are integrated tap systems. So, what does the future look like for water dispensers? And what are the main factors driving the growing demand for mains-fed hydration systems? Environmental consciousness Many studies have been undertaken to determine the environmental impact of plastic water bottles. Conclusions vary widely, but reasonable averages can be extracted. In a 2019 UK survey by INCPEN (Industry Council for Packaging and the Environment) and WRAP (Waste and Resources Action Programme), the focus was on “citizens’ attitudes and behaviours relating to food waste, packaging, and plastic packaging”. More than half of the respondents said they’d become more concerned about food packaging over the past year. Concerns included: impact on oceans and marine life (66%), waste packaging going to landfill (61%), difficulty/impossibility of recycling (58%), and contribution to climate change (41%). Consumers are becoming increasingly aware of, and concerned about, plastic’s detrimental effect on the environment. A mains-fed integrated tap system can potentially eliminate the use of disposable plastic. Take, for instance, Aqua illi – the highest performing tap on the market today – or the innovative Aqua Alto, available in any colour. These water systems can dispense upward of 300 cups (the equivalent of 75 litres) of chilled water – still or sparkling – per hour. If that 75 litres of water were packaged in 500ml bottles (i.e. 150 bottles), the total plastic would weigh approximately 1,500g, representing 4,500g of CO2 emissions. The total volume of water consumed during the production and transportation of these 150 bottles would be 225 litres. According to a 2019 article by Forbes, millennials (or Gen Y) are loyal to companies that care about their effect on society. This generational cohort (people born between 1981 and 2000) make up approximately 50% of today’s workforce, and their values are helping to guide organisations towards sustainable development goals. “Refillability has become an important feature of the dispense market over the last two years.” (Richard Hall, Chairman and founder of Zenith Global) Health consciousness In its 2020 Health and Wellbeing at Work survey report, the Chartered Institute of Personnel and Development (CIPD) revealed that organisations who ran a wellbeing programme were seeing improvement in employee morale and engagement – as well as a drop in sickness absence and increase in staff retention. There’s certainly evidence that a health-conscious generation of 20-40-year-olds (millennials) is shaping a culture of general wellbeing, which is having a huge impact on corporate productivity. The Millennials and Wellness report by American flavour manufacturer, Fona International, reveals that this generation takes a holistic approach to wellness. The focus has shifted away from fad diets and self-denial towards moderation, appreciation for quality, and care of the whole self, including mental health and hydration. Regular hydration is one of the most important factors in maintaining physical and cognitive health. Attractive and accessible hydration stations contribute to a healthy workplace culture, where pure water is a natural part of the working day.
