Is coffee made in unlined copper pot safe?

Copper pots are generally safe to use, with specific considerations depending on the type of liquid being cooked and the level of wear on the pot. However, it is crucial to note that unlined copper pots are not food-safe and should never be used to cook or prepare food.

Here's why:

1. Risk of Copper Leaching: Unlined copper pots can release copper ions into food or drink. High copper intake can be toxic and lead to various health issues such as nausea, vomiting, liver damage, and kidney complications. The acidic nature of coffee can enhance the leaching of copper from the pot, increasing the health risks.

2. Unpredictable Leaching Rates: The rate of copper leaching can vary depending on factors like the type of food or drink being prepared and the pot's condition. It is difficult to control the amount of copper released, making it unsafe for regular use in food preparation.

3. Copper Reaction with Food: Copper can react with certain foods and beverages, affecting the flavor and color. For example, acidic ingredients can cause food cooked in unlined copper pots to taste metallic.

4. Regulatory Compliance: Many countries have regulations and standards regarding the use of copper in food preparation. In some jurisdictions, unlined copper cookware is explicitly banned for commercial food establishments due to the potential health hazards.

Therefore, it is strongly advised to avoid using unlined copper pots for cooking or making coffee. Use food-safe materials such as stainless steel or glass to ensure the safety and quality of your beverages.
