Alcohol in bars cannot be sold after 20:00 until the end of February.
And from March 1 to April 11, the sale of alcohol will be banned after 22:00, the government said in a statement.
The decision, taken on Friday, came amid growing concerns over the third wave of the pandemic. The number of coronavirus cases in Sweden declined rapidly about two weeks ago, but the decline has stalled since then and the health agency has reported an increasing prevalence of variant B117, which is considered more contagious.
The variant of the virus, first reported by the UK, accounted for between 9% and 20% of all cases in four regions studied by the Swedish Public Health Agency last week.
Recall, despite the problems with the supply of vaccines against coronavirus throughout the EU, Sweden does not abandon its intention to vaccinate the entire adult population in the country until the end of June.
