How long does smithwicks last in a keg?
If I'm around, about 4 days...
Kegs are pretty sterile environments (assuming conditions were proper during filling, etc) and Smithwicks is a red ale, so given all of these variables; it'll keep for a good long time.
How long are you thinking of letting it stay in there?
