If you have a bamboo chopping board and a darker carbonised bamboo board side by side, you might have noticed they behave a little differently when you oil them. One seems to drink oil, the other beads it on the surface. So when it comes to bamboo vs carbonised bamboo: which chopping board oils best?
First things first: what is carbonised bamboo?
Standard bamboo boards are made from pale, naturally coloured bamboo. Carbonised bamboo starts exactly the same way but the bamboo is steamed at high temperature. This darkens the sugars in the fibres, giving that rich caramel colour many people love in their kitchen.
The steaming process also changes the structure of the bamboo slightly. It can become a touch softer and a bit more open in grain, which is where things get interesting when we talk about oiling and long term care.
Why oiling matters so much for bamboo boards
Bamboo behaves more like a very hard grass than a traditional wood, but in practical terms you treat it much the same as a wooden board. That means regular oiling. Why?
- Prevents drying and cracking by keeping the fibres conditioned
- Helps repel water so the board does not swell or warp
- Reduces staining and smells from onions, meat juices and colourful veg
- Gives a smoother cutting surface that is kinder to your knives
At Deer & Oak we pre oil our bamboo and carbonised bamboo boards at the factory, but they will still need topping up at home if you want them looking their best for years.
Bamboo vs carbonised bamboo: how each takes oil
Let us look at how the two types of board behave when you apply mineral oil or board cream.
Natural bamboo
Natural bamboo is dense and relatively low in porosity. When you oil it:
- It tends to absorb oil fairly evenly
- You will usually see a gentle deepening of colour, not a dramatic change
- It often needs slightly less oil per treatment
- The surface can feel silky and firm once cured
On our pre oiled bamboo chopping board sets and extra large bamboo boards, you will usually only need a light maintenance coat every month or two, depending on how often you cook.
Carbonised bamboo
Carbonised bamboo has already been through heat, which slightly opens up the structure of the fibres. When you oil it:
- It often looks thirstier at first and can soak up more oil
- The colour can deepen beautifully, with a rich, warm tone
- It may need more frequent oiling especially in the first few months
- Dry patches and light spots show up more easily against the darker background
This is why our carbonised bamboo boards arrive generously pre treated, so you start from a well saturated base rather than a dry, raw surface.
So which chopping board oils best?
If by “oils best” you mean which one soaks up the most oil, then carbonised bamboo wins. It tends to absorb more and show a more dramatic visual change when oiled.
If you mean which is easiest to look after, natural bamboo usually has the edge. It needs slightly less oil and is more forgiving if you forget a maintenance coat now and again.
In everyday use, both oil very well and both can last for years with the right care. The real difference is in how often you need to oil and how fussy the surface looks if you skip it.
- Choose natural bamboo if you want a low fuss, lighter board that still looks smart with fairly minimal upkeep.
- Choose carbonised bamboo if you love the darker look and do not mind spending an extra five minutes with the oil bottle now and again.
The best oils for bamboo and carbonised bamboo
Whatever board you own, the rules about oil are the same:
- Use food safe mineral oil or a dedicated board oil or cream.
- Avoid cooking oils like olive, sunflower or rapeseed. They can go sticky and rancid.
- Wax blends such as mineral oil with beeswax are great for a final protective coat.
Both bamboo and carbonised bamboo respond beautifully to a simple routine: a light coat of mineral oil, then, for extra protection, a very thin layer of wax once the oil has soaked in.
Simple step by step oiling routine
Here is a routine we recommend to Deer & Oak customers. It works for both bamboo and carbonised bamboo boards, as well as our acacia and premium butcher's block boards.
-
Clean the board
Wash with warm water and a tiny bit of mild washing up liquid. Rinse and dry thoroughly with a towel, then let it air dry standing upright until completely dry to the touch. -
Apply oil generously
Pour a small puddle of mineral oil onto the surface. Using a lint free cloth or a piece of kitchen roll, work the oil into the grain in circles, covering all faces and the edges. -
Let it soak
Leave the board flat on a protected surface for at least 20 minutes. Carbonised bamboo may drink the oil quite quickly, so do not be surprised if it looks dry again after a short time. -
Top up if needed
If you see dry patches, apply a second light coat, especially on carbonised bamboo or any end grain areas. -
Buff off the excess
After an hour or so, wipe away any oil that has not soaked in. You do not want the surface feeling tacky. -
Optional wax coat
For extra water resistance, apply a tiny amount of board cream or wax, rub in well and buff to a soft sheen.
How often should you oil bamboo vs carbonised bamboo?
Oiling frequency depends on how much you cook, how you wash your board and the climate in your kitchen, but as a rough guide:
- Natural bamboo: every 4 to 8 weeks for a busy family kitchen
- Carbonised bamboo: every 3 to 6 weeks especially for the first 6 months
A simple test: sprinkle a few drops of water on the surface. If they bead up nicely, your oiling is still doing its job. If they spread and darken the wood immediately, it is time for a fresh coat.
Common mistakes to avoid
Whether you own bamboo or carbonised bamboo, avoid these habits if you want your board to last:
- Soaking in the sink which can cause swelling and warping
- Putting it in the dishwasher the heat and steam are brutal on any natural material
- Using harsh bleach instead, sanitise with white vinegar or a salt and lemon scrub
- Storing flat while damp always let it dry standing up so air can circulate
- Skipping oiling for months especially with carbonised bamboo, which shows dryness quickly
What about other woods like acacia?
If you are comparing options, acacia is another lovely choice. It is a bit more traditional in feel, with a gorgeous grain and a slightly heavier weight. Our pre oiled acacia chopping board sets take oil very happily and sit somewhere between bamboo and carbonised bamboo in terms of thirstiness.
The good news is your oiling routine can be the same across all of them. Once you have a bottle of mineral oil in the cupboard, you are set.
Our honest verdict
So in the bamboo vs carbonised bamboo debate, which chopping board oils best? In truth, they both do, just in slightly different ways.
- Natural bamboo is the easy going workhorse that stays looking smart with a modest amount of care.
- Carbonised bamboo is the handsome, darker board that rewards a little extra attention with a deep, luxurious finish.
Pick the one that suits your kitchen and your habits, then treat it well. Give it a quick wash, let it dry properly and spend a few minutes with the oil bottle every month. Do that and your board will quietly get on with its job for years, no drama, just beautifully chopped onions and neatly sliced sourdough.
