The series began on October 9 to accommodate the World Series, which was scheduled to begin on October 19.TBS televised all games in the United States with Game 1 starting at 4:05pm EDT. Games 1, 2 and 6 were played at Miller Park in Milwaukee, Wisconsin, while the other games were played at Busch Stadium in St. Louis, Missouri. By coincidence, Brian Anderson, who usually calls Brewers games on Fox Sports Wisconsin during the regular season, did the play-by-play for the NLCS on TBS, along with Ron Darling and John Smoltz. Anderson filled in for regular TBS lead baseball announcer Ernie Johnson, who was tending to a son in the hospital.

This was the Brewers' first ever appearance in the NLCS, having moved to the National League in 1998. As an American League team, the Brewers made the ALCS in their pennant season of 1982, defeating the California Angels 3–2. Thus, the Brewers became the first franchise to play in the LCS as a member of each league. The Cardinals, meanwhile, appeared in the NLCS for the first time since winning the 2006 World Series. This was a rematch of the 1982 World Series (a.k.a. the "Suds Series", with both cities associated with the brewing industry—Milwaukee, whose ballpark was named after the Miller Brewing Company, and St. Louis, whose Anheuser-Busch company is namesake of the Cardinals' ballpark), in which the Cardinals won 4–3.
