Our Black Forest Diffuser Oil Refill is the perfect way to refill an existing diffuser or to create a dramatic diffuser accessory of your own. We blend the Black Forest fragrance in small batches and leave the oils to age in barrels. This process allows them to blend, mature, and intensify into a fragrance that is sultry and smooth.

Black Forest Always Delivers
Black Forest has been my go-to candle for year-end holidays and the scent when used as a diffuser doesn’t disappoint. The fragrance is detectable unlike other brands.

It is a wonderful scent. I was looking for Black Currant but that is no longer available. Black Forest is a good substitute.

Great scent!
Bought for a small reed diffuser (< 200 mL) for an apartment living room, so I have some left over. For the price, it'll last me a long time (few months). The scent is nice and woodsy, but it does feel a bit heavy on the nose. It'd be better as a winter scent, or maybe I prefer lighter scents. Regardless, the product is clearly well made. I'll likely be picking up another bottle when I need a refill.
