TECHNOLOGY
Barrels don’t just hold wine—they drive its evolution.
By exposing fresh, toasted oak and reopening the grain, our process restores the barrel’s ability to breathe—reestablishing controlled oxygen exchange essential for proper maturation. The result is more precise oxygenation, better integration, and a barrel that actively supports wine development instead of limiting it.
MICROOXYGENATION
Barrels are critical to a wine's formation.
Barrel aging only works when the barrel still does its job.
For centuries, oak barrels have shaped great wine through two critical functions: controlled extraction and controlled oxygen exchange. When those pathways are compromised by saturated wood, tartrates, and residue, both functions break down—phenolics stall, oxygen flow chokes, and maturation suffers.
Our process restores both.
By renewing the working surface and reopening the grain, we reactivate phenolic contribution and reestablish precise oxygen transfer—returning the barrel to active service in the aging process instead of passive storage.
How it works
-
Oxygen is not a flaw in barrel aging—it’s the mechanism. A healthy barrel allows controlled oxygen transfer through the wood, supporting structure, balance, and long-term wine development.
-
This process—microoxygenation—drives tannin evolution. In the presence of precise, consistent oxygen exposure, small, aggressive tannins bind together into longer-chain polymers. The result is a wine that gains suppleness, integration, and depth instead of bitterness or angularity.
-
Our process protects this pathway. By reopening the grain and restoring the barrel’s ability to breathe, we re-enable polymerization where it matters most—giving full-bodied wines the structure, texture, and aging potential they were designed to achieve.
-
Oak extraction and oxygen exposure are inseparable. A barrel only delivers flavor when oxygen can move freely through the wood. When heavy tartrate buildup and wine-saturated residue block the grain, oxygen transfer drops—and oak contribution drops with it. What remains is a barrel that looks serviceable but no longer performs.
-
Our process restores the system. By removing tartrate crystals and spent surface wood, we reopen the grain and reestablish controlled oxygen flow—maximizing oak expression, improving integration, and returning the barrel to active participation in the aging process.
RISK DOESN’T STAY CONTAINED.
The problem you can’t steam away.
Blisters are silent failure points. We eliminate them before they ruin wine.
Every barrel we process is opened, smelled, and visually inspected end-to-end—because blisters can’t be treated blindly. When we identify wine-filled blisters or compromised wood, we scrape, open, and hand-blast them to remove trapped wine and embedded contamination that would otherwise survive standard cleaning and resurface in the next fill.
If a barrel shows signs of deeper structural or microbial risk, it is immediately pulled from the line. The winemaker is alerted with clear findings and full transparency—so no questionable barrel moves forward by default. Decisions are deliberate, not automatic.
Timing matters because contamination doesn’t wait—and barrels deteriorate fastest when they sit dirty.
The moment a barrel is emptied, residual wine, tartrates, and saturated surface wood begin to oxidize, dry, and lock contaminants deeper into the grain. Blisters harden, tartrate crystals cement in place, and microbial populations gain protection—making them far harder to remove later, even with aggressive cleaning.
Blasting immediately after emptying stops that progression.
At this stage, residues are still soft, the grain is open, and blisters can be identified and neutralized before they become sealed contamination reservoirs. This allows our process to fully renew the working surface, restore oxygen pathways, and reduce the need for elevated SO₂ during storage.
Once a barrel goes into storage dirty, risk compounds.
Early intervention preserves barrel performance, extends usable life, and ensures the barrel re-enters service clean, breathable, and aligned with the next wine’s goals—rather than carrying forward the problems of the last fill.
In short: cleaning late manages damage. Cleaning early prevents it.
