I have a little under 5 gallons of a Wee Heavy Scotch Ale that I wanted to add some French Oak chips to the secondary. I have a four oz. bag. How much and how long? I want a noticeable presence, but not an overwhelming one.
Also, the bag says to soak in water for 12 hours before adding? Why? Is it necessary. Do I need to boil them at any point for sanitation?
