From Monday 26 April, all parts of mainland Scotland will be moved into level three measures, meaning pubs can reopen outdoors under modified restrictions.
Pubs can serve groups of up to six people from up to three households until 10pm. There will be no requirement to serve food with alcohol.
It is hoped there will also be a "limited" reopening of indoor service, with just food and non-alcoholic drinks allowed.
When it comes to indoor trading, venues can serve groups of four from no more than two households until 8pm and must take contact details from customers.
Sturgeon said she did not expect any further changes until 17 May when it was hoped many level three areas would be able to move to level two.
Indoor hospitality can “return to greater normality” from this point, with alcohol served indoors and “more normal opening hours,” Sturgeon said.
Aiming for normality
This will involve an indoor closing time of 10.30pm with a two-hour dwell time and a 10pm outdoor curfew.
Up to four people from two households will be allowed to socialise indoors from Monday 17 May.
The Government will assess the situation in the summer but “will be aiming for as much normality as possible,” Sturgeon said.
From early June, it is hoped all of the country will move to level one, where hospitality can operate until 11pm.
Up to six people from no more than three households can socialise indoors while up to eight people from three households can socialise outdoors at this stage.
"This is certainly the most hopeful I have felt about the situation for a long time," Sturgeon said.
Scottish trade bodies had been calling on the Government to scrap the previous requirement for food to be served with alcohol, in addition for longer opening hours.
They had called for something similar to England's reopening system, where there will be no curfew.
Garden centres and hairdressers will be allowed to reopen from 5 April, weeks ahead of hospitality.
