The following answer to questions was from the Star-K
Keeping You Kurrent January, 2002.
Can a consumer purchase fresh-brewed flavored coffees from uncertified coffee shops and assume that it is kosher since the consumer-packed coffees
are certified kosher?
When purchasing fresh-brewed flavored coffees from coffee shops one CANNOT ASSUME that this coffee is the same product that is sold in a sealed
kosher certified consumer package bearing the shop's name. Consumers have to determine the following:
- Are the coffee beans and flavor syrups properly marked with a reliable kosher certification?
- Even though some flavored coffees are certified, are you sure that all the varieties sold at this establishment are certified kosher?
- Do the creamers, flavored and regular, bear reliable kosher certification?
- Are the carafes/pump pots used exclusively for kosher coffees, or do they interchange between kosher and non-kosher?
- Are the coffee cups, stirrers, etc., disposable?
If you answered YES to all of the above, you may drink the coffee..
