Industry News: How Climate Change Affects Organic Herb Sourcing for Tea

Climate change is reshaping agriculture worldwide, and the organic herb tea industry is no exception. For brands like Heath & Heather, which pride themselves on sourcing premium organic ingredients, shifting weather patterns pose significant challenges. From droughts altering peppermint yields to unpredictable frosts affecting camomile harvests, the ripple effects are felt from farm to cup.

This article explores the key ways climate change impacts organic herb sourcing for tea, the industry's response, and how Heath & Heather is adapting to maintain quality and sustainability. Understanding these dynamics helps tea lovers appreciate the care behind every bag.

Shifting Growing Regions and Crop Viability

Traditional herb-growing regions are experiencing altered rainfall and temperature extremes. For example, camomile thrives in temperate climates, but rising temperatures in parts of Europe have led to smaller flower heads and reduced essential oil content. Similarly, peppermint requires consistent moisture; prolonged droughts in North America have cut yields by up to 20% in some years.

Organic farmers, who cannot use synthetic pesticides or fertilizers, are especially vulnerable. They rely on healthy soil and natural pest control, both disrupted by climate volatility. As a result, some growers are moving to higher altitudes or latitudes, but this is not always feasible. Heath & Heather works closely with organic farms to monitor these shifts and diversify sourcing to ensure steady supply.

Quality and Potency Under Threat

The flavour and therapeutic compounds in herbs are influenced by growing conditions. Stress from heat or water scarcity can alter the concentration of active ingredients. For instance, research shows that drought-stressed peppermint produces less menthol, affecting its cooling sensation. Camomile may have lower levels of bisabolol, a key anti-inflammatory compound.

For organic tea brands, maintaining consistent taste and efficacy is paramount. Heath & Heather's quality control includes testing for marker compounds. If a harvest falls short, they may source from alternative organic farms with better conditions. This flexibility helps preserve the signature profiles of teas like Peppermint Organic Herbal Tea Bags and Camomile & Spearmint Organic Herbal Tea Bags.

• Tip: Look for brands that transparently share their sourcing practices and quality testing.

Supply Chain Disruptions and Price Volatility

Extreme weather events—floods, wildfires, storms—can damage crops and infrastructure. In 2024, unseasonal rains in southern Europe delayed the harvest of lemon verbena and caused mould issues. Such events lead to supply shortages and price spikes. Organic herbs already command a premium; climate disruptions can push costs higher.

Heath & Heather mitigates this by building long-term relationships with growers and investing in sustainable farming practices. They also maintain a diverse portfolio of herbs, so if one crop is affected, others can compensate. This approach ensures that popular blends like Lemon & Ginger Organic Herbal Tea Bags remain available and affordable.

Adaptation Strategies: Organic Farming and Resilience

Forward-thinking organic farms are adopting regenerative practices to build resilience. Techniques like cover cropping, composting, and agroforestry improve soil health and water retention. Some farmers use shade nets to protect delicate herbs from intense sun or install drip irrigation to conserve water.

Heath & Heather supports these efforts through its sourcing policies. They prioritise suppliers who implement climate-smart agriculture. For example, the camomile used in Night Time Organic Herbal Tea Bags comes from farms that rotate crops to maintain soil fertility. Such practices not only safeguard supply but also align with the brand's commitment to environmental stewardship.

• Tip: Choose teas from companies that invest in regenerative organic agriculture.

What This Means for Tea Lovers

Climate change may subtly alter the taste or availability of your favourite herbal teas. You might notice a slightly different aroma in a batch of camomile or a milder peppermint. However, brands like Heath & Heather are proactive in maintaining consistency through careful sourcing and blending.

By purchasing organic teas, you support farming practices that are better for the planet. Organic agriculture reduces carbon emissions and enhances biodiversity, helping combat climate change. Every cup of Heath & Heather tea is a step toward a more sustainable future.

Climate change is a pressing reality for organic herb sourcing, but with thoughtful adaptation, the tea industry can continue to deliver quality and sustainability.
