The Marlborough methode was launched five years ago to mark the 100th birthday of his mother, Dawn.
Yesterday, on the occasion of Dawn’s 105th birthday, he presented her with a bottle of the latest vintage, which has now had the label reprinted to reflect the latest milestone passed by the matriach of the family.
"She’s still going strong and still not out," Mr Ibbotson said.
"I may have to change the label a few more times yet."
Born in Gore in 1914, Mrs Ibbotson (nee Smith) married the late Arthur "AK" Ibbotson, in 1938.
In 66 years of married life in Dunedin, the couple raised three children, Russell, Neal and Ruth-Mary.
"None of us are in Dunedin, so we have all travelled especially to be here," Ruth-Mary James said.
"It’s not every day someone turns 105."
A recent broken ankle had her making the move from her own home to Yvette Williams Retirement Village.
She still moves very quickly though, blowing out the candle on a birthday cake before ODT illustrations editor Stephen Jaquiery was ready to capture the passing of time.
