Tasmania Police has identified one of the men as 48-year-old Wayne Barratt, who died on August 28.

The name of the second man, who died two days earlier, is yet to be released.

Methanol poisoning was raised as a possible cause of death when home-made spirits and a still were found in one of the men's homes in the St Helens area.

Police and health authorities were quick to issue public health warnings about consuming home-made liquor out of fears that it had been responsible for the men's deaths.

But an interim report following a post- mortem found no trace of alcohol in one of the men and only a little in the other man's system.

An analysis of the milky white spirit located at the home also showed no methanol was present.

Methanol, a form of alcohol, is a by-product of distilling and can be deadly if ingested.

The North-East Division's Acting Inspector Jason Jones said other causes of death were now being investigated.

"The early toxicology report didn't come back with anything in the way of indicating alcohol being a factor," he said.

It will now be for the coroner's office to determine the cause of the men's death, he said.
