Pioneer flour mill


Built by Carl Hilmar Guenther, the mill was once located on the edge of Live Oak Creek. Though it no longer exists, the original barn, main house, guest house and smokehouse remain today serving as a Texas Historical Landmark. These landmarks are currently undergoing restoration to celebrate the rich history of the founding families of Fredericksburg.

land acquisition


The land is acquired by Van Chester and Peggye Pagel Brown who use the land primarily for farming, while raising their three children.

first production


Peggye develops an interest in wine making and crafts the family's first wines. After their death, the land was divided between the three children and Dabs Brown Hollimon inherited the current vineyard land.

vineyard vision


John Hollimon, being guided by his daughters, saw the potential for a vibrant vineyard and knew his wife would help to make it happen. The family quickly began work combining the spirit of the barn, the farming done by the Browns, and the emerging Texas wine market, to start a vineyard on the property.

production begins


Both the vineyard and the winery officially begin wine production and 1851 Vineyards is born. The 16 planted acres include Cabernet, Tannat, Malbec, Petite Sirah, Tempranillo, and Alvarinho. The tasting room opened in October of 2016 with award winning wines and the help of their children.

new beginnings


The Hollimon family retires and full ownership is assumed by long time partners; The Jones family. In January of 2020 the property is rebranded as Slate Mill Wine Collective. With substantial expansions to the vineyard, winery and tasting room the Collective welcomes boutique Texas brands to produce their wines with expertise of an accomplished winemaking team and a venue in which they can promote their products. A 'village' of small tasting rooms available for winemakers to lease is projected to be added making Slate Mill the first full service 'winery incubator' in the state and a unique addition to the wineries of Fredericksburg, TX.
