Starbucks, Dunkin’ & Other Coffee Shops: Getting Your Caffeine Boost In-Town and On-the-Road

By: Rabbi Baruch Beyer

Summer 2023

The STAR-K Hotline receives no end of calls from coffee heads who dote on their daily cup of joe, whether from a local Starbucks or a Dunkin’ on the road. Recent changes in Starbucks’ company policy vis-à-vis kosher have further elevated the confusion for the kosher coffee connoisseur. Let’s dive in to clear out some of the haze.

Unflavored roasted coffee beans, whole and ground, are considered kosher without a hechsher. Bearing this in mind, buying a cup of unflavored regular or decaf coffee should not present any kashrus issues. Some coffee vendors, however, sell kosher and non-kosher items, like bacon and ham-filled sandwiches. The keilim used for coffee and the treif items are at times washed together, causing blios (absorbed tastes) from the treif utensil to enter the coffee equipment.

For example, at Starbucks, it’s been established that the brew basket that holds the coffee grounds while the coffee is […]

Cool Drinks for a Hot Summer Day: A Review

By: Rabbi Tzvi Rosen

Summer 2023

Each summer the STAR-K Hotline fields hundreds of questions from concerned kosher consumers, thirsty to know: Is my Slurpee kosher? Do smart waters need a hechsher? What are the concerns with shaved ice and sno-cone stands? We stand ready to quench your thirst for information!

Carbonated Beverages

Carbonated beverages involve two major processes: compounding the flavor bases to create the flavor, and bottling the finished product when the sweetening agents, carbonation and water are added.

Soft drinks are compounded into soda flavor bases at one of three locations: the bottling facility, a separate technical center dedicated to blending soda emulsions, or an outside flavor house. In the latter case, the flavor house will create custom emulsions with specifications laid out by the soft drink company.

Regardless of the location, the most intensive part of kosher soft drink certification entails compounding, since this is when the kashrus of the flavors, colors, oils and blending […]

Insights From the Institute: The Mesorah on Duck Eggs

By: Rabbi Mordechai Frankel

Summer 2023

Q: My local farmer’s market sells duck eggs. Can I assume that they are kosher?

A: Although the Torah lists twenty-four non-kosher species of birds, we no longer know precisely to which species the Torah is referring.[1] The Gemara provides alternative ways to ascertain whether a bird is kosher, but notes an instance in which a mistake in identification transpired.[2] For this reason, Rashi states that we do not rely on the Gemara’s criteria, and we eat only the few species of birds for which we have a mesorah (oral tradition) that attests to their kosher status.[3]

The Baal Ha’maor, one of the Rishonim, maintains that he has a tradition that all birds with wide feet and a wide beak – those more or less resembling a goose – are deemed kosher if they meet the Gemara’s criteria.[4] The Shulchan Aruch […]

Why the “D” in Non-Dairy?

By: Rabbi Tzvi Rosen

Summer 2023

The Merriam-Webster Dictionary offers the following definitions for the noun dairy: the department of farming or of a farm that is concerned with the production of milk, butter, and cheese; milk from a cow or other domestic animal (such as a goat); and food (such as ice cream, cheese, or yogurt) made primarily of or from milk.

Today, a dairy is far more than a producer of milk products. If we were to explore a modern-day dairy, a far more accurate definition would be: an establishment that processes milk; milk products, such as ice cream, buttermilk and yogurt shakes; non-dairy alternative frozen desserts; non-dairy novelties, such as ices and popsicles; and non-dairy beverages, such as juices, fruit punch and tea.

Unquestionably, liquid milk production is the bread and butter of a successful dairy plant. Juices and teas are suitable side dishes and, of course, the pièce de resistance is ice cream […]
