The factory was established in 1876 in McPherson Street, Casterton, which is still its present site, by Ben Jeffreys using bottling equipment shipped out from England. He operated it until 1903 when his two sons took over, adopting the trade name "Jeffrey Bros". In 1946 Mr Bill Young purchased a third share in the firm and held it until 1956 when he sold it back to the Jeffreys family.
Graeme Jeffreys, a grand-son of Ben Jeffreys, then joined the firm making this the third generation of Jeffreys to be associated with the business. He originated the sales name "Big J" and introduced a 30oz bottle using his grand-father's initials "B.J". The firm remained in the family until 1969 when it was purchased by Messrs. Phillips and Johnson, who up until the present time [1973] still trade under the name of Jeffreys Bros.
Jack Phillips and 'Kiwi' Johnson also purchased the Portland Aerated Water Company and 'Kiwi' moved to Portland to run the business whilst Jack Phillips remained in Casterton to run Jeffreys Bros. Jack was a former Casterton policeman.
