The popular Scot polled hundreds of votes since his star turn at Croft before the mid-season break, when he secured race wins to put him third in the driver standings.
He polled 44 per cent of the vote, beating Andrew Jordan (25 per cent) and Steven Kane (9 per cent).
He said: "I don't normally win awards like this so it is very nice to receive this recognition from so many fans. I get a massive buzz from being behind the wheel and I consider myself as one of the luckiest guys alive to be racing in this series.
"To win the HiQ Champagne Moment just makes things even sweeter and I look forward to getting my hands on the bubbly!"
David Arneil, of Falkirk, was picked at random to present Gordon with his bottle of champagne and will also win a bottle for himself, as well as a grid walk and a pair of complimentary weekend race passes.
HiQ's marketing manager Geraldine McGovern said: "We thought the champagne moment award would be between Gordon and Andrew, and so it proved.
"The only thing we were surprised at was the fact that Gordon hasn't won a champagne moment before now. He's not only a popular driver, but an extremely talented one and we wish him well at Snetterton this weekend."
