Lapsang souchong tea side effects have become a growing concern among health-conscious tea drinkers, despite this distinctive beverage’s long history and unique flavor profile. While black tea accounts for 90% of all tea consumed in the western world, few varieties have sparked as much controversy as this pine-smoked delicacy.
Unlike traditional black teas, Lapsang Souchong undergoes a special smoke-drying process over burning pinewood, creating its characteristic smoky taste that has made it particularly popular in Europe. However, this same smoking process has raised serious health questions. In fact, European authorities have expressed concerns about smoked teas due to the presence of Polycyclic aromatic hydrocarbons (PAHs), particularly four molecules known as PAH4, which are toxic, carcinogenic volatile compounds. These molecules are lipophilic, meaning they can cross cell membranes, potentially affecting our health in ways many tea drinkers never consider.
In this article, we’ll explore what makes Lapsang Souchong unique, examine the scientific evidence behind its potential health risks, and discuss why some countries have restricted or even banned this distinctive tea. Additionally, we’ll uncover other side effects that doctors rarely mention when discussing this smoky brew.
What makes Lapsang Souchong different from other teas
First and foremost, Lapsang Souchong stands apart from other teas through its unconventional production method. Rather than traditional air-drying or pan-firing techniques used for most teas, Lapsang Souchong undergoes a distinctive smoking process that fundamentally transforms its character.
How it’s made: the smoking process
Traditional Lapsang Souchong, known as Zheng Shan Xiao Zhong in Mandarin, is produced in a multi-story smokehouse with slotted bamboo floors. The process begins with tea leaves (typically two or three layers down from the flower buds) being withered over pine fires, then pan-fried, rolled and oxidized.
What truly sets this tea apart is the final stage—the leaves are placed in bamboo baskets and hung on wooden racks over smoking pinewood fires to dry and absorb the smoke. This process occurs in a special building called a “Qing Lou,” where smoke from burning pine enters through the flue, permeating the tea leaves through small gaps in the bamboo mats.
The smoking isn’t merely a finishing touch—it’s an integral part of the tea’s identity. The unique chemical compounds from pine smoke, especially longifolene and α-terpineol, aren’t found in any other tea varieties. These compounds create the distinctive flavor profile that makes Lapsang Souchong immediately recognizable.
What does Lapsang Souchong tea taste like?
The flavor profile of Lapsang Souchong is truly distinctive. Upon steeping, this robust, full-bodied tea reveals layers of complexity. The initial sip presents bold smokiness accompanied by subtle hints of pine and fruitiness.
As the tea lingers on your palate, a medley of sweet and woody undertones emerges. Many describe notes of pine resin, smoked paprika, dried longan, and comparisons to peated whisky. Yet underneath the prominent smoke character lies a natural sweetness—high-quality versions even yield a longan fruit flavor that persists through multiple infusions.
Why it’s popular in the West but rare in China
Interestingly, although Lapsang Souchong originated in China, it’s rarely consumed there. Instead, it’s primarily produced as a valuable export for European and American markets.
The historical explanation for this cultural difference is fascinating. Dutch and English traders became captivated by this tea because the oxidized leaves withstood long ocean voyages better than delicate green varieties, whose higher moisture content invited mold. By 1760, the British East India Company was shipping 62,900 pounds of Lapsang Souchong according to the Annual Register.
Moreover, the strong smoking of the tea is considered an adulteration by many Chinese tea connoisseurs, explaining why black teas generally—and smoked varieties specifically—aren’t particularly popular in China despite their overwhelming popularity in Western countries.
The distinctive smoking process that gives Lapsang Souchong its characteristic flavor simultaneously introduces potentially harmful compounds into the tea leaves. Behind the aromatic profile lies a chemical reality that has prompted scientific scrutiny and regulatory action in recent years.
What are PAHs and why they matter
Polycyclic aromatic hydrocarbons (PAHs) are organic compounds consisting of fused aromatic rings formed during incomplete combustion of organic matter. These molecules are lipophilic, meaning they aren’t soluble in water but can cross cell membranes. Once inside cells, PAHs interact with cytochromes, producing molecules that form adducts with DNA, potentially leading to gene mutations. This mechanism explains why many PAHs are classified as carcinogenic substances.
Is Lapsang Souchong carcinogenic?
The question of carcinogenicity centers on specific PAHs found in smoked tea. Four molecules—benzo(a)anthracene, chrysene, benzo(b)fluoranthene, and benzo(a)pyrene—collectively called PAH4, are particularly concerning. Notably, benzo(a)pyrene has been classified as a human carcinogen by the International Agency for Research on Cancer. Essentially, these compounds form on tea leaves during the smoking process, raising legitimate health questions about lapsang souchong tea side effects.
How much PAH actually ends up in your cup?
Fortunately, PAHs are mostly insoluble in water, with studies indicating that only about 5% of these compounds transfer from leaves to tea infusion. Research shows that PAH concentrations in tea infusions are significantly lower than those on the leaves themselves. One study found PAH4 concentrations ranging from 5.2 to 17.6 μg/L in black tea infusions, while another determined that an adult consuming one cup of tea would ingest approximately 0.078 ng/kg of benzo(a)pyrene.
Comparison with grilled foods and smoked meats
Interestingly, the levels of PAH4 in smoked tea leaves are 10 to 100 times lower than those found in commonly consumed cooked meats. Furthermore, scientific reviews indicate that consumer exposure to PAHs via tea infusions is “very low and safe for health”. The European Food Safety Authority considers health concerns associated with dietary PAH exposure to occur at Margin of Exposure values below 10,000—a threshold tea infusions typically don’t approach.
Why some countries have banned or restricted Lapsang Souchong
Regulatory concerns about lapsang souchong tea side effects have sparked controversy across Europe, yet the full story differs from the headlines suggesting outright prohibition.
Lapsang Souchong banned in Europe: what really happened
Contrary to popular belief, Lapsang Souchong hasn’t been completely banned in Europe. The European Commission raised legitimate concerns about smoked foods and teas containing potentially carcinogenic compounds. Since 2015, stricter regulations on Polycyclic Aromatic Hydrocarbons (PAHs) have eliminated certain products from the market. Nevertheless, compliant versions remain legally available throughout the EU.
France and Germany’s stricter standards
France and Germany, in particular, have implemented substantially tighter standards beyond those established by the European Commission in 2015. Consequently, their 2017 health standards effectively rendered most traditional smoked teas unsaleable. These countries’ domestic health agencies have taken a more cautious approach toward PAH4 levels, even as the broader EU maintains somewhat more permissive regulations.
How producers are adapting to new regulations
Tea producers have demonstrated remarkable adaptability facing these challenges. Many have revised their manufacturing methods by:
Incorporating filtration techniques and roasting processes
Replacing traditional smoking with artificial flavoring
Selecting alternative woods producing lower PAH4 levels
Reducing direct exposure of leaves to smoke
Better controlling temperatures during production
Such innovations have yielded PAH-free products that meet even the strictest European standards. Still, replacing authentic versions proves challenging—Twinings attempted substituting their traditional blend with “Distinctively Smokey,” which customers described as “stale cigarettes”.
Beyond PAHs, Lapsang Souchong presents several less-discussed health considerations worth examining if you consume this distinctive tea regularly.
Caffeine content and its impact
Lapsang Souchong contains 30-60 milligrams of caffeine per cup, roughly half that of coffee. This moderate amount can provide a gentle energy boost but might cause jitters, insomnia, or increased heart rate in caffeine-sensitive individuals. Likewise, overconsumption may lead to headaches, dizziness, and even digestive irritation.
Heavy metals in tea leaves
Tea plants readily absorb environmental contaminants. Studies reveal that tea leaves often contain heavy metals like lead, cadmium, mercury, and chromium. Indeed, these compounds can leach into brewed tea, potentially causing cardiovascular, immune, and endocrine system diseases with long-term exposure. Contamination rates vary by tea type, with white and yellow teas showing lowest pollution levels.
Tooth staining and oral health concerns
The tannins in black teas, including Lapsang Souchong, bind to tooth enamel, causing noticeable discoloration. Furthermore, studies demonstrate that adding milk significantly reduces tea’s staining ability, primarily through casein protein. Brushing immediately after drinking tea also helps minimize staining.
Digestive sensitivity in some drinkers
Some individuals experience digestive discomfort when consuming black tea. The tannins may trigger heartburn or nausea, primarily when consumed on an empty stomach. Hence, pairing Lapsang Souchong with food often mitigates these effects for sensitive drinkers.
Final Thoughts: Should You Drink Lapsang Souchong Tea?
Lapsang Souchong tea certainly stands as one of the most distinctive and controversial tea varieties available today. Though prized for its unique smoky flavor profile, this pine-smoked delicacy carries potential health considerations worthy of attention. Most notably, the presence of Polycyclic Aromatic Hydrocarbons (PAHs) has prompted European authorities to implement stricter regulations, especially in countries like France and Germany.
Nevertheless, scientific evidence suggests the actual risk remains relatively low. PAH transfer rates from leaves to infusion hover around just 5%, resulting in significantly lower exposure compared to commonly consumed grilled foods. Still, consumers with health concerns might prefer seeking out newer, regulation-compliant versions produced with modified smoking techniques.
Beyond PAH concerns, additional side effects deserve consideration. Caffeine sensitivity affects some drinkers, while others might experience digestive discomfort from tannins, particularly when consumed on an empty stomach. Heavy metal absorption and tooth staining represent other potential issues, though drinking tea with milk can mitigate staining effects.
Weighing these factors against the pleasure of enjoying this distinctive beverage becomes a personal decision. Moderate consumption likely poses minimal risk to most healthy adults. Pairing your tea with food, limiting daily intake, and selecting high-quality sources can further reduce potential concerns.
