During the California Gold Rush, gold dust served as the preferred currency. A miner would open his purse of gold, offering merchants and barkeeps to take a pinch of dust as payment. Prosperous merchants were said to have 'Fat Thumbs,' thanks to a reputation for taking generous pinches of gold.

In blending Argonaut Fat Thumb, the Master Distiller showed he too had a 'Fat Thumb' when pulling from Alembic Brandy stocks. The resulting blend showcases the quality of the scarce blending legs.
