In Peet’s shops, coffee is served within 30 minutes of brewing to ensure freshness. Peet’s also provides the “roast on” and “purchase by” dates on the coffee bags, which Starbucks doesn’t do.
Actually, it does. At least, when I worked there (many, many, many moons ago) brewed coffee had a 30 minute lifespan before being dumped, as a matter of policy. Of course, I have no doubt that certain employees are loose with this rule, be it at Starbucks or any other chain of coffee house… but as a matter of policy, Starbucks does have a 30-minute rule for brewed coffee.
I don’t recall a roast on date, on their whole bean coffee, but there most certainly is a sell by date.
