On Wednesday, Seoul said the delegation would include Kim Yo-jong, the younger sister of North Korean leader Kim Jong-un, spurring expectations she could deliver a message from the regime.
The North Korean tabloid Chosun Ibo also speculated that beer has been in works since at least 2015, after that the leader of the country, Kim Jong-un, complained that beers imported from South Korea are too bland.
The cheer squad arrived in the South alongside 26 taekwondo performers, 21 journalists and four North Korean Olympics committee members, the Unification Ministry said.
Koh Yu-hwan, a North Korea expert at Seoul's Dongguk University, said Kim Yo Jong, as Kim Jong Un's relative and apparently one of the few people who has earned his absolute trust, carries more weight as a dialogue partner for the South than any other official the North could send.
South Korean President Moon is hoping to translate the Olympic cooperation into deeper engagement with Pyongyang.
Kim Yo Jong, who is believed to be in her late 20s, was promoted last October by her brother as an alternate member of the politburo, the party's decision-making body.
Kim Yo-Jong "has frequently been seen standing close to her brother at major state events, an indication of her closeness with him and the regime".
Speculation is growing that the nation will hold its first military parade in 10 months to showcase its long-range ballistic missile one day before the opening of the PyeongChang Olympic Games in South Korea.

South Korea, which is hosting the games, had asked the International Olympic Committee to decide whether the song's content was acceptable, but officials decided to make the cuts themselves while the IOC was still deliberating.
Quarantining patients for 48-72 hours and rushing out hand sanitisers to venues are among the urgent measures officials have taken and American biathlon Lowell Bailey admitted that he had concerns.
That set off a rapid series of meetings which saw the two Koreas agree to march together at the opening ceremony and form a unified women's ice hockey team, their first for 27 years.
Hundreds of North Koreans have arrived in South Korea ahead of the Opening Ceremony on Friday.
Pyongyang told Seoul that Choe Hwi, chairman of the National Sports Guidance Committee, would travel to Pyeongchang as part of its delegation.
Meanwhile, a more pressing matter for officials of the PyongChang Olympics is a possible outbreak of the highly contagious norovirus after more than 30 security guards fell ill in recent days.
