Following its release in April 1999, Zucker went straight to No. 2 in the German albums chart. Songs from the album were introduced in the Rosenstolz concert tour which took place in Germany and Switzerland during May and June 1999. In an interview, singer AnNa R. of Rosenstolz described the album as being more personal than earlier Rosenstolz albums. She further stated that the album was more mature in terms of the lyrics and the themes dealt with, attributing this to the fact that the band members were getting older.
Two songs featured in the album, "Perlentaucher" and "Fütter deine Angst", reached No. 40 and No. 52, respectively, in the German singles chart. "Fütter deine Angst" was part of a double single with "Ja, ich will", and the latter together with "Zucker III" were included in a re-release of Zucker as bonus songs. "Ja, ich will" was a collaboration with German comedienne Hella von Sinnen, calling for the introduction of same-sex marriage.
