High-Efficiency Lauter Tun False Bottoms
Maximize your brewhouse yield with precision-engineered wedge wire floors. Designed for optimal wort flow, easy grain removal, and decades of reliable service in craft and industrial breweries.
The Standard in Modern Lautering Technology
A Lauter Tun False Bottom is the foundation of a successful mashing process. Our false bottoms utilize V-wire (wedge wire) technology, which provides a significantly higher open area compared to traditional milled or perforated plates. This results in faster lautering times and clearer wort.
- Precision Slotting: Standard 0.7mm to 1.0mm slots to retain fine grains while allowing maximum wort flow.
- No Clogging: The V-shaped profile ensures only two-point contact with husks, preventing "blind" spots.
- Heavy-Duty Build: Reinforced to handle the weight of deep grain beds and high-pressure differentials.
Advanced Features
Increased Extract Yield
Better flow distribution means you extract more sugars from your grain bed, improving overall efficiency.
Faster Vorlauf & Lauter
Reduced resistance in the floor speeds up the brewing day without compromising wort clarity.
Segmented Construction
Custom-made in "pie-shape" segments to fit perfectly through your vessel’s manway for easy installation.

Design & Customization
Manway-Friendly Segments
We design our false bottoms in interlocking segments. This allows you to upgrade your existing lauter tun by passing the new floor through the manway without cutting the vessel. We can integrate center-outs for rakes/agitators, manway access hatches, and drainage ports directly into the screen design.
Why Wedge Wire over Perforated Plate?
Open Area: Wedge wire typically offers 2-3x more open area than milled plates.
Cleaning: Wedge wire’s V-profile releases particles easily; perforated holes tend to trap grain husks.
Durability: Fully welded wedge wire is significantly more rigid and resistant to warping under heat.
Frequently Asked Questions
Most craft brewers prefer 0.7mm or 0.75mm. This offers the best balance between wort flow and preventing grain husks from passing through.
Yes, we specialize in custom-fit replacements for any OEM lauter tun. We only need your vessel’s internal diameter and support height.
Segments are designed to sit tightly together on a support ring, often secured with “hold-down” bars or bolting to ensure they remain flat during the mash-out.
