Gokuri Rich Apple

About
Gokuri Rich Apple is a fruit beverage sold by Japanese brewer and bevrages company, Suntory. It is one of the products that make up their lineup of "Gokuri" drinks.
24% of the drink consists of apple juice, so what sets it apart from plain apple juice? 
The answer is the apple fibers that are inside the drink. The fibers give the impression that you are actually drinking freshly squeezed apple. These fibers are what all the Gokuri drinks share in common with each other.

Compared with the other Gokuri drinks, Rich Apple may not have as much impact, but it still is a good drink.

Gokuri Sweet Pineapple

Gokuri Sweet Pineapple is a fruit drink sold by Suntory in Japan, and is part of the "Gokuri" series. The drink contains 15% juice consisting of pineapple and lemon juice, sugar, fruit fibers, and fruit extract.

Taste
The fruit fibers give the drink an impression of freshly squeezed pineapple juice. However, since the drink is not 100% juice, it is not as viscous and is easier to drink than pure juice.
This makes the drink an excellent thirst-quencher during the hot Japanese summers.
