Towards the end of the war and in the immediate post-war period, the distillery increased production and was running at full capacity by 1948. The number of stills was increased from two to four during 1977. Water supply became a concern during the 1980s when development of the land around the Tarlogie Springs seemed likely. Development could have reduced the quality and quantity of water available to the distillery, so the decision was made to purchase around of land around and including the Tarlogie Springs. The distillery once again engaged in expansion during 1990 when it added a further four stills, and two additional fermentation vessels (or "washbacks") were added during 2002. Four new stills were added in 2009, bringing the total to twelve.
