Bach regularly directed a musical ensemble based at
Zimmermann's coffee house called a
collegium musicum, founded by
Georg Philipp Telemann in 1702. The libretto suggests that some people in eighteenth-century Germany viewed coffee drinking as a bad habit. However, the work is likely to have been first performed at the
coffee house in Leipzig. The cantata's libretto (written by
Christian Friedrich Henrici, known as Picander), features lines like "If I couldn't, three times a day, be allowed to drink my little cup of coffee, in my anguish I will turn into a shriveled-up roast goat". Bach wrote no operas: the cantata was written for concert performance, but is frequently performed today fully staged with costumes. == Scoring ==
