Looking to do an Oaked Scottish 70

but cant figure out how much oak chips to add. Thinking about 1.5 oz of american oak soaked in whiskey. Too much? Too Little? Original gravity is estimated at 1.039 and IBUs at 12.

How about no whiskey, how to sterilize?

I use 1 cup water per oz of chips and boil for 10-15 min

If you want the flavor contribution of the whiskey then go with that otherwise I would just boil.

How much oak chips?

I oaked a stout with 1 oz of oak chips steamed for 15 minutes then soaked in Jameson for a couple weeks (the guy at the LHBS told me whisky wasn't strong enough to kill everything). The amount of oak isn't the only important thing to consider; how long do you want it to sit on the oak and how long afterwards until you want to taste it. My stout was with on the oak for 3 weeks, but I aged it a month after removing from oak before I tasted, and it was GOOD.

On a Scottish ale, I wonder how soaking the oak in scotch would be...
