Lithuanian saying?

I have once seen the following phrase:
"Alus snakus, alutis snakutis"
which, according to my informant, is Lithaunian.
In it would be rendered something like:
"Beer makes you garrulous, a fine quality beer stimulates a nice
conversation".
Or perhaps "…a not excessive amount of beer consumed…"
Apart from addition of diacritic signs, is this correct?
Does any lithuanophone person recognize this?
If fairly correct, is the ending –utis diminutive?
Se non è vero ...
