Records of the farm date back to 1842 when the land was first settled by James A. Gallaher. A patent was granted in 1845. In 1846, the land was assessed at $3.00/acre, but by 1870, the value had risen to $20.00/acre. In 1844, James A. Gallaher died leaving the land to his widow, Mary T. Gallaher who later split the land between her son, John A. Gallaher and Sarah E. Gallaher, the widow of her deceased son, James R. Gallaher. Montserrat Vineyards was a part of the property conveyed to Sarah E. Gallaher. However, due to various debts of her deceased husband, she ultimately had to sell the property to pay off her debts. Her brother-in-law, John A. Gallaher, was the highest bidder and bought 80 acres for $1,204.00.

In 1876, John A Gallaher subdivided part of the 80 acres as Gallaher's First Addition to the Town of Montserrat. Block T is still a part of Montserrat Vineyards. It was said that John A Gallaher named the town Montserrat because it reminded him of the mountains surrounding the Monastery of Montserrat in Spain. He was an entrepreneur involved with coal mining (using prison labor) and brick making, along with his land development. He built the original someplace and it was a beautiful home in its day, providing an exceptional view in three directions.

John A. Gallaher was also the first State Geologist and his report of the status of minerals in the State was published in 1900, shortly after his death.

The property has had an interesting history, especially since the late 1800's. Its gardens were unparalleled in the county and a grand and ornately constructed gazebo dominated the scene. This structure is pictured in the Johnson County Historical Society records and is typically Victorian in motif. John's wife Katherine was an invalid and spent many a plesant hours in her "summer house." When she died, Katherine was buried on "the hill", but her body was later moved to a more suitable cemetary location.

During the period 1904-1980, no less than six families occupied the property. Reports from family members imply that life was lively in those happy, carefree and unsophisticated days.

In August of 1980, David and Maxine Pearson purchased the property. It by now was overgrown with brush, scrub, and endless fencing. They cleared, plowed, and sowed to wheat in 1980 and planted the first 2 acres of grapes in the spring of 1981 and a 1/2 acre of blueberries that fall. They continued to add, modify, and improve "Blueberry Hill Farm" into 3 acres of grapes, 1 1/2 acres of blueberries, and 3/4 acre in miscellaneous berries and brambles.

In 1994 its current owner Dr. Phillip Weinberger, as a new home site, purchased Blueberry Hill Farm. The farm continued to operate as a "you-pick" fruit farm, producing blueberries, blackberries, raspberries, gooseberries, asparagus, along with grape varieties including Vidal, Seyval, Stuben, Niagra, and Catawba.

In 1997, Weinberger made a decision to remove the assorted berries and replace them with additional grapes. In the year following, "Montserrat Vineyards" became a licensed, bonded Missouri winery. Today the winery produces approximately 2,000 gallons of wine annually. Three of which have won bronze medals at the Indiana International Wine Competition. Two new vineyards, Norton and Traminette bring the total vineyard area to five acres.

In June 2006 Dr. Weinberger and Kelly Frankum were married on the property. Together with their children, they have created a happy and successful family business.
