The INFINI by TEDEM method is a patented thermo-oxidative regeneration process that restores barrels without shaving, while fully respecting the wood and its original toasting.
The treatment works deep within the oak to fully restore the barrel’s properties.
A complete action on the wood
The method allows:
- removal of colored compounds and “old wood” flavors
- elimination of aromatic defects (dry, austere notes…)
- complete disinfection of the barrel
(bacteria, Brettanomyces, molds…) - removal of residual sulphur
- preservation of the barrel’s structural integrity
👉 Result: clean, healthy, neutral and stable wood.
A barrel ready for use
After treatment, the barrel is:
- fully decolorized
- disinfected
- free of residual SO₂
- with a light, clean and non-aggressive oak profile
It regains a fully usable profile, free from defects.
Two finishing levels
🔹 Mineral Range – regeneration only
- No tannin addition
- Original toasting preserved
- Light and precise oak impact
👉 Ideal for:
- white wines
- rosé wines
- delicate aging
- spirits seeking a neutral support
👉 Base: a clean, sound, defect-free barrel.
🔸 Range with tannin injection into the wood
After regeneration, the aromatic potential can be reactivated
by injecting oenological tannins directly into the staves.
🎯 Available profiles
Fresh
Brings tension and aromatic freshness
👉 Ideal for whites, rosés, fruity wines
Tancor
Toasted, buttery notes with richness
👉 Reinforces the oak core
Sweet
Vanilla, smoothness, biscuit notes
👉 Round and indulgent effect
Intense
Powerful structure, mocha / roasted notes
👉 Suitable for concentrated red wines and spirits
🛡️ Final stabilization
Before delivery, an SO₂ treatment is carried out.
Upon reception, its presence should be checked.
If necessary, additional sulphur ensures complete stabilization.
♻️ A sustainable method
The INFINI by TEDEM method is part of a strong environmental approach:
- biomass-generated steam
- use of filtered rainwater
- reduced carbon footprint
- maximized barrel lifespan
👉 Objective: enhance a resource that can last up to 200 years.
✅ Summary
An INFINI by TEDEM barrel is:
- 0% shaving
- healthy, defect-free wood
- no residual sulphur
- infinitely regenerable
- adaptable (neutral or aromatic profile)
- an eco-friendly and responsible method
