From package revel you have:

var (
    // Loggers
    TRACE = log.New(ioutil.Discard, "TRACE ", log.Ldate|log.Ltime|log.Lshortfile)
    INFO  = log.New(ioutil.Discard, "INFO  ", log.Ldate|log.Ltime|log.Lshortfile)
    WARN  = log.New(ioutil.Discard, "WARN  ", log.Ldate|log.Ltime|log.Lshortfile)
    ERROR = log.New(&error_log, "ERROR ", log.Ldate|log.Ltime|log.Lshortfile)
)

From package log you have:

func New

func New(out io.Writer, prefix string, flag int) *Logger

New creates a new Logger. The out variable sets the destination to which log data will be written. The prefix appears at the beginning of each generated log line. The flag argument defines the logging properties.

From package ioutil you have:

var Discard io.Writer = devNull(0)

Discard is an io.Writer on which all Write calls succeed without doing anything.

Therefore, to turn off the revel.INFO log try:

revel.INFO = log.New(ioutil.Discard, "INFO  ", log.Ldate|log.Ltime|log.Lshortfile)
