The Simple Answer: Yes, Alcoholic Tea Contains Caffeine
For most commercially available alcoholic tea products, the answer is a resounding yes. Brands like Twisted Tea are brewed using real black tea leaves, and since the tea plant, Camellia sinensis, naturally contains caffeine, so does the final product. The caffeine content, however, is typically modest compared to a standard cup of coffee. It is not an added ingredient but rather a natural component retained from the tea brewing process. The specific amount can vary based on several factors, including the type of tea used and how it is processed.
Hard Tea vs. Homemade Alcoholic Tea
While commercial products offer a consistent caffeine level, homemade versions can be highly variable. The caffeine content will depend entirely on the type of tea, the amount of tea leaves used, and the steeping time. Herbal teas, such as chamomile or peppermint, are naturally caffeine-free and would produce an uncaffeinated alcoholic beverage if used as a base. However, if you use black or green tea, the caffeine will be present in the final mix, which can have unpredictable effects when combined with alcohol.
How Much Caffeine Is In Hard Tea?
To understand the caffeine level in a typical alcoholic tea, it's helpful to compare it to other common beverages. A standard 12-ounce can of Twisted Tea, for example, contains approximately 30 milligrams (mg) of caffeine. This is notably less than a typical 8-ounce cup of coffee, which can range from 95 to 200 mg, but is comparable to a 12-ounce can of cola.
Here is a comparison table to illustrate the caffeine content across different drinks:
| Beverage | Serving Size | Approximate Caffeine Content (mg) | 
|---|---|---|
| Coffee | 8 ounces | 95–200 | 
| Black Tea | 8 ounces | 40–70 | 
| Green Tea | 8 ounces | 20–45 | 
| Twisted Tea | 12 ounces | ~30 | 
| Cola | 12 ounces | 30–45 | 
| Energy Drink | 8 ounces | 80–150 | 
The Complexities of Mixing Caffeine and Alcohol
The combination of caffeine, a stimulant, and alcohol, a depressant, creates a unique and potentially dangerous dynamic in the body. Caffeine speeds up the central nervous system, increasing alertness and potentially masking the sedative effects of alcohol. This can lead to a dangerous situation where a person feels less intoxicated than they actually are and may be more likely to consume additional alcohol. The caffeine does not affect the rate at which the body metabolizes alcohol; only time can do that. This means that while a person might feel more awake, their blood alcohol content (BAC) remains elevated, and their judgment and motor skills are still impaired.
Risks of Combining Stimulants and Depressants
Mixing alcohol and caffeine can have several negative consequences. Studies have shown that drinkers who combine the two are more likely to binge drink and experience alcohol-related harm. This can include an increased risk of alcohol poisoning, dependence, and poor decision-making. The combination can also increase heart rate, blood pressure, and cause dehydration. For this reason, many health authorities advise against mixing alcoholic beverages with caffeine.
Brewing and Production Methods That Affect Caffeine Levels
The amount of caffeine in a tea-based alcoholic beverage is not static. It depends heavily on the production process, whether commercial or homemade. Several factors play a role in caffeine extraction during brewing:
- Tea Type: Different types of tea leaves naturally contain varying amounts of caffeine. Black tea generally has the highest content, followed by oolong, green, and white tea. The exact variety of tea plant used can also influence the result.
- Water Temperature: Caffeine dissolves more readily in hot water. Brewing with boiling water extracts more caffeine than using cooler water. Traditional brewing methods for black tea use hotter water than those for green or white tea, resulting in higher caffeine concentration.
- Steeping Time: The longer the tea leaves steep, the more caffeine is released into the liquid. A short steep time will produce a lower caffeine beverage, while a longer steep will increase the concentration.
- Brewing Method: Techniques like cold-brewing, which involve steeping tea in cold water for an extended period, significantly reduce caffeine extraction compared to hot brewing. This can be a useful method for home brewers aiming for a lower caffeine content.
- Blends: Some products, like the Twisted Tea Half & Half (tea and lemonade), contain less actual tea, and therefore less caffeine per serving, than the standard variety. Blending tea leaves with other ingredients, like herbs or dried fruit, also reduces the overall caffeine content per cup.
Hard Tea vs. Hard Kombucha
While alcoholic tea and hard kombucha are both fermented, tea-based alcoholic beverages, they differ in their fermentation process and caffeine content. Traditional kombucha is fermented with a SCOBY (symbiotic culture of bacteria and yeast), resulting in a low alcohol by volume (ABV) and a small amount of residual caffeine from the tea base. Hard kombucha undergoes a secondary fermentation process to increase the ABV to levels comparable to beer or hard seltzer, typically ranging from 4% to 10%. Like hard tea, the caffeine content in hard kombucha depends on the tea used but may be naturally lower due to the fermentation process.
Important Health and Safety Considerations
The combination of a stimulant and a depressant should always be approached with caution. The CDC and other health organizations have warned about the dangers of mixing alcohol with caffeine, emphasizing that the caffeine can mask the effects of alcohol, leading to an increased risk of alcohol-related harm. Consumers should be aware of the following:
- Impaired Judgment: Feeling more alert from caffeine does not mean you are less impaired by the alcohol. Your coordination and decision-making abilities are still affected.
- Increased Risk of Binge Drinking: The masking effect can lead to consuming more alcohol than intended, increasing the risk of binge drinking and alcohol poisoning.
- Dehydration and Heart Issues: Both alcohol and caffeine are diuretics that can cause dehydration. The combination can also place extra strain on the heart, leading to increased blood pressure and irregular heartbeat.

Conclusion: The Final Verdict on Caffeine in Alcoholic Tea
In conclusion, if you are consuming a product labeled as alcoholic tea, you can almost certainly assume it contains caffeine from the real tea leaves used in its production. While the amount is typically lower than in a cup of coffee, it is not insignificant. The combination of caffeine and alcohol is not a safe one, as the stimulant effects can hide the depressive effects of the alcohol, leading to overconsumption and increased health risks. Understanding the source and amount of caffeine in these beverages is crucial for making informed choices about your health and safety. For those looking to avoid caffeine entirely, options made with herbal infusions are the only truly caffeine-free tea-based alternative.
