Results
Recommended Rate
75 g/hL
30-90 g/hL trial band
Lot Addition
2,823 g
37.9 hL treated
Bench Bottle
0.559 g
750 mL bottle dose
Heat Stability Gap
26.0 NTU
Current rise minus target rise
Heat instability of 28.0 NTU points to a starting bentonite dose around 75 g/hL, or 2,823 g across the lot.
Warnings
Bench trials are mandatory before any bulk bentonite addition.
Hydration method and contact time change performance. Confirm the cellar SOP before scaling.
