Traquair House Brewery lies in the wing of the house directly underneath the Chapel. It dates back to the early 1700’s and was originally a domestic brewery serving the house and the estate. It was disused in the early 1800’s but never dismantled. It gradually filled with the family junk until it was completely forgotten.
Peter Maxwell Stuart rediscovered the brewery in the early 1960’s and began brewing again as an experiment in 1965 using all the original equipment and fermenting the ales in the original oak tuns, some of which were over 200 years old. Footage has recently come to light showing the 20th Laird brewing with his daughter (the present 21st Lady of Traquair).
