If you don't want any liquor flavor in the beer,you can soak the chips in vidoka in an airtight container in the fridge during fermentation. Or wait till you're ready to rack to secondary to boil them in a small amount of water (1C or so). Let that cool,covered,then pour all through a hop sock into secondary,tie iff the sock,& drop it in. Rack beer onto that. Check it in 3-7 days to see if the flavor is to the desired level. A shot glass is plenty for this test.
