Oak Chips provides the mildest flavor including some sweet vanilla hints.
The flavor of oak also can be changed by toasting your oak. The dark toasted oak has a more carbonized or carmelized flavor while lightly toasted or untoasted oak has a much more mild flavor
Oak Chips are the most popular form used in home brewing – typically the Oak chips look like wood shavings. The small chips have a large surface area which delivers the oak flavor to the beer quickly. The only disadvantage is that the small chips can be hard to separate from the finished beer, so it is important to have them in a grain or hop bag so they can be easily removed after aging.
Dosage: 14g – 28g per 20 litres of beer.
Three major methods are available to home brewers (Taken from Beersmith):
- Oak Aging – The simplest method – which involves adding the oak chips/spirals/cubes after fermentation while aging the beer. Also this is the method used with barrels, since you store the beer in the oak barrel. I recommend sanitizing the chips/spirals/cubes first by steaming them for 15 minutes to reduce the risk of infection (don’t use sanitizing solution as it is absorbed by the chips). Most home brewers add their oak shortly after fermentation completes and before bottling (i.e. in the secondary) and leave the oak in there until they achieve the desired taste – sampling every day or two. Some brewers with keg systems also add the oak chips/cubes in the keg itself – containing it in a bag so it will not block the keg’s dip tube. Oak aging can take anywhere from a few days to several months depending on the oak used and desired flavor level.
- Oak Tea – You can boil the oak to make an oak tea. Simply drop your chips/spirals/cubes in enough water to cover them fully and bring it to a boil for 10-15 minutes. Once the tea is complete you can add it a bit at a time to the finished beer until you achieve the overall beer flavor you desire. Making a tea is much faster than aging with oak, and also lets you more closely control the flavor.
- Liquor Tea – If you are looking to add burbon, whiskey or your favorite liquor flavor to the beer you can make a tea using liquor instead. In this case you add the chips/cubes/spirals to a small amount of your favorite liquor (possibly diluted a bit with water) and let it sit for a week. Then mix the liquor in with you beer in small amounts until you achieve the desired overall flavor. Obviously moderation is important here as the liquor can easily overpower the flavor of the beer or wood chips.
