Ancelotti told a post-match news conference preparation had been far from ideal but he expects Bayern's supreme domestic pedigree to show, from next Friday's Bundesliga clash with Bayer Leverkusen onwards.
"Of course the title is important," he said. "I'm pleased. We played with good concentration,"
"Our pre-season hasn't been good but you don't need to worry. When the season starts, we will be there."
Sven Ulreich, deputising for the injured Manuel Neuer, was the hero for Bayern with penalty saves from Sebastian Rode and Marc Bartra.
"We know that preseason hasn't gone as well as we had wanted but we saw the Bayern that everyone wants to see, especially in the first half when we had lots of chances," he told ZDF.
"We should have used these [chances] better and we also conceded two sloppy goals. In the end, we showed great morale, getting the result we wanted. We have to continue in this manner."
Ulreich added: "Of course, I'm pleased to have helped the team in a penalty shootout and win a title."
