A Kiddush cup is a central ritual object for any Jewish holiday, from weekly Shabbat celebrations to Rosh Hashanah, Yom Kippur, and more. With the help of a Kiddush cup, Jewish people honor God and sanctify holidays. After reciting the Kiddush and drinking from the Kiddush cup, holidays officially begin. 

Read on to learn everything you need to know about Kiddush cups, including what Kiddush is, how Kiddush cups are used, and how to choose the perfect Kiddush cup for your home. 

What is Kiddush? 

In order to understand what a Kiddush cup is, it’s important to first understand the Jewish practice of Kiddush. Kiddush, Hebrew for “sanctification,” is one of the primary rituals in Judaism. It has two purposes: to thank God and sanctify the time that follows. 

Depending on the holiday, Kiddush can happen slightly differently, but generally it follows the same process. First, a cup is filled with wine or grape juice. This cup is known as the Kiddush cup. Next, the Kiddush prayer is recited. Finally, the Kiddush cup is passed around so everyone can take a sip. After this ritual is recited, everyone has officially entered holy time. 

Origins of Kiddush

The origins of the practice of Kiddush stretch back to sometime between the 6th and 4th centuries BCE. Like today, it was common at the time to drink wine with a celebratory meal. The rabbis introduced Kiddush as a way to designate a holy meal from a simply celebratory meal. 

Until the Middle Ages, Kiddush was largely reserved for meals in private spaces and was not recited in synagogues. As traveling away from home became more common, rabbis began to say Kiddush in synagogue so that travelers could still hear the blessings. Thus began today’s practice of Kiddush. 

When is a Kiddush Cup Used?

Kiddush cups are used any time the Kiddush prayer is said. This may include any Jewish holiday, from the weekly Shabbat holiday to high holidays like Rosh Hashanah, Passover, and more. Read on to learn the differences between Kiddush on each of these holidays. 

Shabbat Evening Kiddush

On Shabbat evening, three prayers are recited before drinking from the Kiddush cup. First, Torah verses about the holiness of Shabbat are recited. Then, a blessing is said over the wine in the Kiddush cup. Finally, a blessing is said to thank God for the gift of Shabbat. 

Shabbat Morning Kiddush

Before the Shabbat daytime meal, commonly known as Kiddush or oneg, the Kiddush cup is filled once again. A blessing is said over the wine, then the meal is enjoyed. 

High Holidays Kiddush

On high holidays like Rosh Hashanah and Yom Kippur, the Kiddush cup is used again and slightly different prayers are said. The Kiddush said on high holidays is specific to the holiness and significance of each holiday. A prayer called the Shehecheyanu, which thanks God for special occasions, is also said. 

What Makes a Cup a Kiddush Cup?

According to Jewish law, in order for a cup to be a Kiddush cup, it must meet the following standards: 

  • Size: A Kiddush cup must hold at least 3.8 fl. oz. of liquid. 

  • Condition: A Kiddush cup must not have cracks or holes. 

  • Cleanliness: A Kiddush cup must be clean. 

According to these standards, there are no specific requirements regarding the material your cup is made from. While silver and ceramic kiddush cups are the most common, a glass or even a disposable cup is acceptable in a pinch. 

Common Types of Kiddush Cups 

While nearly any cup can be a Kiddush cup, some are more common than others. You may find the following when shopping for one: 

  • Silver Kiddush cup: Traditionally, many Kiddush cups are sterling silver. They’re long-lasting and can be passed down through the generations, but they have some requirements in terms of maintenance, like regular polishing. 

  • Ceramic Kiddush cups: Ceramic Kiddush cups are a modern alternative that fit with nearly any design style. Like silver Kiddush cups, they’re long lasting, but they don’t have the same requirements in terms of maintenance. 

  • Keepsake Kiddush cups: Kiddush cups are a common gift for bar mitzvahs, weddings, and other special occasions. These cups may feature engraved messages or special motifs that commemorate the occasion.
