Leon McTaggart pleaded not guilty to wounding Narinder Sindhu with intent to cause him grievous bodily harm.
Unemployed McTaggart further denied possessing an offensive weapon - a knife - in Hagley Road West.
Mr Sidhu was stabbed up to five times at Simply Fish and Chips in Hagley Road West on November 6 last year.
Judge John Wait sitting at Wolverhampton Crown Court further remanded McTaggart in custody for trial.
Mark Phillips, prosecuting, told the Judge that the trial - set to begin on June 6th - was expected to last for up to four days.
McTaggart, who appeared before the court via a video link from HMP Woodhill near Milton Keynes, spoke only to confirm his name during the short hearing.
Michael Anning, defending, told the court a bail application could be made on behalf of McTaggart at a future hearing.
Mr Sidhu, who has made a full recovery from his injuries, was attacked in his shop as his 16-year-old daughter peeled potatoes in a back room.
An appeal launched after the attack promised a £2,000 reward for information leading to an arrest and conviction.
