The Talk of the Town “White Mos” is Back! A Tasting Report on 4 New Mos Burger Products | A “Giant White Mos” Appears at the Ebisu Higashi Store This Year!?
Hello! I am Ozuto from the Social Relations Bureau, Division 2, and I joined the company as a new graduate in April 2023.
It may be sudden, but that “White Mos Burger,” which sold 3.5 million units last year, has made a comeback!
The product we are introducing today is the “White Mos Burger,” available at Mos Burger for a limited time from July 12 to mid-September 2023!
This is an arrangement of Mos Burger’s signature product, “Mos Burger,” topped with a generous amount of white cheese sauce. It caused a huge stir last year, surpassing 3.5 million units sold. Many of you may already be familiar with it or have been hoping for its return.
This year, the White Mos has returned with an upgraded cheese sauce, evolving from four types to five types of cheese (Cream, Gouda, Emmental, Parmesan, and White Cheddar).
SUNNY SIDE UP was in charge of the “Natsu Mos 2023” New Product Media Presentation and Tasting Event held to commemorate this milestone launch.
As a PR representative, in order to convey the appeal of the White Mos Burger and the other new products not only to the media but also to our readers, I personally went to taste the “White Mos Burger”—which is already creating a buzz with its five types of cheese—along with three other new products designed to blow away the summer heat!
■ Heading to the Mos Burger Ebisu Higashiguchi Store
Upon visiting the Ebisu Higashi store, a giant White Mos Burger monument immediately caught my eye!

This monument reportedly represents the size of 4,149 “White Mos Burgers” sold at the same store last year, and seeing it in person is truly impactful!
There were many people enjoying taking photos in front of the store.
*The exhibition has since concluded.

The sight of the white cheese sauce overflowing from between the buns and tomatoes is full of sizzle and truly whets the appetite.
The new “White Mos” has a revised cheese blend, reducing the acidity to create a mild flavor that is easy for children to enjoy.
When I actually tried it, the five types of cheese blended intricately in my mouth, making it feel almost as if I were drinking cheese…
The combination of the refreshing, slightly acidic cheese sauce—perfect for summer—and the meat sauce is outstanding.
At the “Natsu Mos 2023” New Product Media Presentation and Tasting Event held before the launch, the developers took the stage to discuss their dedication during development and the key points regarding the cheese blend changes from last year. This led to successful buzz and exposure not only in gourmet and lifestyle media but also on TV programs.
We also received a great deal of feedback from consumers on social media!

■ Many Other Limited-Time New Products Besides the White Mos Burger!
In addition to the White Mos Burger, several other new products perfect for this summer are being released one after another.

This is the Hot Spicy Mos Chicken, a summer-limited product that has been sold in 2021 and 2022, receiving high praise every year from spicy food lovers. Seasoned with several types of spices such as smoked paprika, coriander, and Sichuan pepper, the tingling spiciness of the spices matches the crispy coating perfectly, boosting the summer appetite.

Next, we introduce the new drink products, which are essential for any set meal.

Left: “Lime & Lychee Soda,” Right: “Tea Sangria <Non-Alcoholic>”
“Lime & Lychee Soda”
This refreshing carbonated drink combines fresh fruit juice with a fizzy sensation, making it the perfect companion for the White Mos or chicken!
Using lime juice grown under plenty of sunlight and lychee juice from South Africa, you can enjoy a crisp acidity and a sweet aroma.
The bottom contains chunks of aloe pulp, providing a pleasant, chewy texture.
“Tea Sangria <Non-Alcoholic>”
This mocktail is made by mixing an original base using red wine from France—one of the world’s three major wine-producing countries—with the popular Mos Burger staple, iced tea.
The red wine undergoes vacuum concentration, which lowers the boiling point to evaporate only the alcohol. It also contains large slices of fresh orange, so if you drink it while crushing the fruit with a spoon, the flavor becomes even fresher.
Since it is non-alcoholic, it can be enjoyed by all generations in any setting!
