Elevating your range

We work with our clients to provide them with the oak or wood necessary to complement or premiumise their recipe. We then let the customer focus on what they do best – curating their sprit – while we get to work on the logistical side – from procuring, building, quality controlling and supplying on time.

Our team thrives on creating novel oak and wood concepts for our clients, allowing them to find exotic solutions whilst not ignoring practical quality, volume needs and timelines. And to develop a new recipe or work on R&D options for the future. We support them with their desired flavour profile, colour, liquid character and desired deadlines.
