What Is Original Oil™?
Grothouse’s Original Oil™ is a proprietary, food-safe mineral oil wood finish designed for butcher block countertops and wood surfaces meant to be used. Original Oil™ penetrates deep into the wood fibers, allowing the material to remain fully renewable over time.
At a glance, Original Oil™ is:
- A food-safe wood finish suitable for direct contact
- Clear and non-pigmented, preserving true species color
- A penetrating oil finish—not a surface coating
- Free of tung oil and suitable for those with nut sensitivities
It can be applied to edge grain, flat grain, and end grain constructions, but at Grothouse, Original Oil™ is the only finish specified for end grain butcher block countertops.
That pairing is intentional.
End grain construction exposes the wood’s cellular structure vertically, allowing fibers to absorb impact and self-heal under use. Original Oil™ supports this by conditioning those fibers from within—maintaining resilience, durability, and long-term performance.

The Look & Feel of an Oil-Finished Wood Countertop
Original Oil™ leaves the wood visually honest. What you experience is the material itself: the grain, the variation, the depth of the species.
Over time, oil-finished wood countertops develop a subtle patina as they interact with light, touch, and daily use. Tones deepen slightly. The surface softens. The finish evolves naturally within the space.
For designers, this offers something increasingly rare: a surface that doesn’t resist change, but responds to it.
Performance: Why Oil Finishes Work for Butcher Block
Because Original Oil™ penetrates rather than seals, it supports the wood’s ability to regulate moisture—helping reduce drying, surface checking, and long-term stress within the material.
As a food-safe butcher block oil finish, it is ideal for direct-use surfaces.
Most commonly specified for:
- End grain butcher block countertops
- Kitchen islands used for food prep
- Integrated chopping surfaces
Wear is not a failure of the surface—it’s part of how butcher block is designed to function.
Knife marks and use patterns can be sanded out and renewed with fresh oil, restoring the surface without replacement. This renewability makes oil-finished wood countertops a long-term solution for both residential and commercial applications.
Design Applications for Oil-Finished Wood Countertops
Original Oil™ is often specified in spaces where material authenticity and warmth are central to the design.
It pairs naturally with:
- Furniture-style kitchen islands
- Handcrafted or inset cabinetry
- Layered, material-forward interiors
While most commonly used on end grain butcher block countertops, it can also be applied to edge and flat grain surfaces where a softer, more organic finish is desired.
Who Should Choose a Butcher Block Oil Finish?
Original Oil™ is best suited for clients who:
- Want a food-safe wood surface for daily prep
- Value the natural character of real wood
- Prefer a renewable finish over a permanent coating
- Appreciate patina and material evolution
It’s a finish chosen not for perfection—but for authenticity.
How to Maintain Butcher Block Countertops with Original Oil™
Original Oil™ is designed to be maintained through simple, periodic care that keeps the wood conditioned and performing at its best.
General butcher block care guidelines:
- Reapply oil approximately once per month, depending on use
- New countertops may require more frequent oiling initially
- Clean with mild soap and water, then dry promptly
- Avoid harsh or chemical cleaners
If wear becomes more pronounced, the surface can be lightly sanded and re-oiled—restoring the countertop to like-new condition.
A Finish That Invites Living
Original Oil™ allows wood to do what it was meant to do—respond, adapt, and evolve.
It’s not about preserving a perfect surface. It’s about creating one that lives well, ages gracefully, and becomes more meaningful with use.
And in that way, it becomes more than a butcher block oil finish.
It becomes part of the life happening around it.
