Nineteen of Medvedev's 21 championships have been achieved on hard surfaces
A resurgent the Russian player won his initial championship for nearly 30 months with success over Frenchman Moutet in the competition title decider.
Medvedev, a former number one, has experienced a torrid year, winning just one match at the Grand Slams and suffering a difficult moment at the US Open.
Medvedev's varied form on the professional circuit - and struggles with his service game in particular - resulted in him falling of the world's top 10 and ultimately splitting with former trainer his previous coach.
Currently training with Johansson and Goetzke, Medvedev has steadily improved in the last few weeks - peaking in a tightly fought competitive triumph over challenger Corentin Moutet.
This marks his maiden trophy after the Rome competition and first on a hard surface from spring of that year.
Victory also signifies Medvedev has won 21 titles at 21 distinct events.
"For the first time I am participating in a event with my both daughters together, so to get a title is really nice," stated world number 14 Daniil Medvedev.
"This title is in honour of my younger daughter her name, because the first title I achieved when my first daughter my daughter was born was for her."
The tennis star, the former major winner, had lost his last six title deciders, featuring in the German tournament in the past months.
Medvedev's retrieving approach and frequent reactions on the playing surface had caused some to wonder if his skill to play at the highest level was finished.
Yet the athlete has implemented adjustments in the last few weeks, attempting to advance forward and play positively, backed up by an improved service.
Medvedev fought back from a disadvantage in the first set against the difficult Frenchman, taking 4 of the concluding five exchanges to take the lead.
Both players swapped break points in the following set before Moutet, striving for his maiden ATP Tour victory, seized the initiative to create a decider.
He rescued 4 initial opportunities in a tight deciding set before the Russian broke to that score to close out the victory.
Appropriately, he earned victory with a point at the front of the court, with Moutet failing to control a volley after two hours and 38 minutes.
