From an KegWorks add:

George Washington: Beer Enthusiast
The father of our country was also the father of American
craft brewing. Washington housed a serious English-style
Porter brewing operation at his Mt. Vernon estate for two
reasons; he wanted to eliminate dependence on foreign
goods to further the colonies' independence and he loved
beer so much, he couldn't bear the thought of running out.

Grover Cleveland: A Man of Excess
Cleveland was known for his beer belly and it was common
knowledge that he drank beer daily. In 1870, during a race
for district attorney in Erie County, New York (where
KegWorks is located!) the future president and his opponent
agreed to only drink four glasses of beer each day to be as
alert as possible for the election. After a few days, they
decided that the cap was too harsh and retracted it.

Franklin Roosevelt: Greatest Drinking President of All
FDR repealed Prohibition, effectively ending the Great
Depression. Just five days after his inauguration, he held a
special congressional session to re-legalize beer. Upon
signing the 21st amendment on December 5, 1933, he
stated, "I believe this would be a good time for a beer."
