DAMIAN McAtamney will not let his mates go dry during the three State of Origin games after being named the home brew section grand champion.

The 2019 Roma Show Home Brew Section had the most entries in its history but it was MrMcAtamney's scotch, described as "smooth and subtle", that quenched the judges' thirst.

Mr McAtamney's scotch not only took out the spirits class with a bottle of Johnnie Walker Red Label reward but he also took out overall champion, winning his weight in beer.

The 32-year-old from Roma weighed in at 58kg to take home five cartons of Great Northern Super Crisp.

Mr McAtamney said the win took him by surprise but a few close mates were stoked with the result.

"Well, I thought we might drink the five cartons over the three State of Origin games, me and the boys will chill down a couple of cartons every match," he said.

"The missus can have the scotch."

This year was the first time MrMcAtamney entered the competition. He said five years of trial and error had finally given him a winning recipe.

"What goes into a winning bottle? That is a special secret," he said.

"Trust me, there has been a lot of trial and error, I'm still trying to perfect it.

"I was sitting at a mate's house having a couple of quiet drinks and he said to me, 'oh, you should put this in the Roma Show', so I thought 'well, why not?"

Mr McAtamney said his friends got him into brewing but he had no intention of increasing his winning supply.

"The funny thing is, my mates got me into it but I'm the top dog now and they're going to be asking me for advice."

Home brew section chief steward Cameron O'Neil said home brewing in the southwest was of high quality.

"We were really happy with the number of entries this year and that has got a lot to do with the great prizes from the Commonwealth Hotel who jumped on board as key sponsors," Mr O'Neil said.

"I hope everyone ... brewing for the next 12 months enters the competition next year."
