The phylloxera aphid, scientifically known as Daktulosphaira vitifoliae, is a tiny insect that had a devastating impact on vineyards of France’s wind producing regions in the late 19th and early 20th centuries. While it is not directly related to whiskey production, the decline of wine production (and the subsequent decline of brandy production that followed) allowed whiskey to fill the void for the main ingredient in blended drinks of the day.
The aphid fed on the roots and leaves of the grapevines causing extensive damage, and eventually lead to the decline and death of the vine. French vineyards, especially those in regions like Bordeaux and Burgundy, suffered immense losses.
Whiskey producers of the day in neighbouring Scotland seized the opportunity and increased production rapidly. With the thirst for cocktails and drinks ever increasing, bartenders increasingly incorporated whiskey into their blended drinks and created great demand for the spirit.
While the phylloxera aphid’s impact was primarily on the wine industry, its history is an important part of understanding agricultural challenges, and also had a profound effect on the ability for whiskey to replace Brandy as the drink of choice for the decades that followed.
