The supermarket giant was forced to temporarily shut 14 stores
Philip McHugh, 51, of Clitheroe, Lancs, was remanded in custody until 8 August by magistrates in Stevenage.
He faces two charges of blackmail and two of making bomb hoaxes.
Hertfordshire police said no other person was being sought in connection with the inquiry. Threats saw Tesco stores evacuated on 14 July.
Stores were temporarily closed in Port Talbot, south Wales; Pontefract, West Yorkshire; Market Harborough and Ashby de la Zouch, Leicestershire; Bury St Edmunds, Suffolk; Hucknall, Nottinghamshire; Hereford and Ledbury, in Herefordshire; Barnes, south-west London, and in East Renfrewshire and Fife.
The other closures took place in regions covered by the Lancashire and Humberside police forces.
The stores reopened after searches of the buildings and surrounding areas.
Police said Mr McHugh, who will next appear at Luton Crown Court, was arrested in Clitheroe on 23 July.
Hereford was one of those affected by the incident 
Hertfordshire police have charged a man with four offences after 14 Tesco supermarkets in the United Kingdom were closed after the company received threats. Stores across the country were affected by the security alert earlier this month.

The man has been named as Philip McHugh, aged 51, from Clitheroe, Lancashire, in the north-west of England. He has been charged with two charges of blackmail and two of making bomb hoaxes, and was due to appear at Stevenage Magistrates' Court this morning. 

Assistant Chief Constable Gary Kitching from Hertfordshire police said, "Throughout the whole inquiry public safety was of paramount importance to both ourselves and Tesco. The successful charging of Philip McHugh has come about through the hard work and tenacity of officers and police staff not only from Hertfordshire but from other forces, and we thank them for their support."

Tesco's Retail and Logistics Director, David Potts commented on the investigation, saying, "Throughout this series of events, the safety of the public and our staff was always our top priority and we worked closely with the police to respond quickly and responsibly. These were of course worrying threats and I am pleased that an individual has been arrested and charged."

"I would like to thank Hertfordshire Constabulary and the other agencies involved for their efficient handling of this investigation. I would also like to thank our staff who acted so professionally during the security threats to reassure customers and get stores back open as soon as possible. The response from customers was fantastic. They were so understanding about the disruption and I am extremely grateful for their patience and continued loyalty," Mr Potts said.

Police are not looking for anyone else in connection to the incident.
