I am trying to determine how low I can drill a hole in my kettle for a spigot. I've read as few as 1.5 to as much as 3.0 inches. What's a good point that will clear the kettle trub for most if not all beers, taking into account higher OG beers/hops beers, without clearing it too much?
If it matters, I'll be brewing on an induction cooktop, so I won't have to worry about the heat from a propane flame on the spigot. Does this change the equation?
Edit -- Obviously this would depend on the size of the kettle and the typical size of a batch. I have a 10 gallon kettle and will be brewing 5 gallon batches.
