"You have people who are there for some time, people who are standing at the bar while tasting for some time and not necessarily conscious of their spacing to other people and standing next to people they don't otherwise know," she said.

Professor Bennett said there was little evidence that a shared tapas plate or bottle of wine had led to more exposure or transmission, and moving in shared spaces remained the biggest issue.

Professor Bennett said given the Delta variant had a shorter incubation period after exposure, speedy contact tracing was critical

"It can just delay that contact tracing a little bit more and means that if there has been exposure sites they could be spread across the state or across state borders, if they're open."

Professor Bennett said there were little things that could be done to provide extra protection to patrons enjoying a glass of wine in the future

"If you can put more space between tables, keep people further apart in distance and over times so that they're not immediately walking into the space, or just increasing your airflow if you're indoors — all of those things help," she said
