Which president drank 1 gallon of coffee a day?

The president often associated with drinking a gallon of coffee a day is Thomas Jefferson.

While there's no definitive proof of the exact quantity, historical accounts and anecdotes suggest he was a heavy coffee drinker.

It's important to note that:

* There's no official record of Jefferson's daily coffee intake. So, the "gallon a day" claim is likely an exaggeration or folklore.

* Jefferson did own a coffee plantation and was known for his love of coffee. This contributes to the association of his name with copious coffee consumption.

So, while the exact amount is unknown, it's fair to say Jefferson was a passionate coffee drinker, and the "gallon a day" myth likely stemmed from his fondness for the beverage.
