buddy just oaked an American IPA. Oak chips went in for 6 days in primary after fermentation stopped with a 1/2 oz of cascade, came out great! can't wait to try it again in a few more weeks.
Side note: cubes take longer to work than chips. Less surface area on cubes and can have a "sealed" side from when it was a barrel.
Chips work faster. 2 ounces for about a week, seems about right for me.

Son, you are a walking violation of the laws of nature, but youre lucky, we don't enforce them laws.
