Grainfather GF30 Fermenter Coat — Insulation Jacket for GF30 Conical Fermenter

The Grainfather GF30 Fermenter Coat is a purpose-built insulation jacket designed for brewers running the Grainfather GF30 Conical Fermenter with a GC2/GC4 Glycol Chiller or Cooling Pump Kit in warm or humid environments. Constructed from 5mm thick SBR foam and engineered as a two-part wrap that fits the GF30 precisely, this coat eliminates the heavy condensation that forms on the outside of a cold fermenter in hot, humid conditions — protecting your floor, your equipment, and your brewery space from the persistent dripping that glycol-cooled fermentation inevitably produces when ambient temperatures are high.

What makes the GF30 Coat a genuinely necessary accessory for brewers in warm climates is the physics of cold fermentation in humid air. When a glycol chiller drops the fermenter temperature significantly below ambient, the stainless steel surface of the vessel rapidly chills the surrounding air below its dew point — and condensation forms on the outside of the fermenter in quantities that can drip continuously throughout a multi-day fermentation run. The 5mm SBR foam coat insulates the cold vessel surface from the warm ambient air, preventing that temperature differential from reaching the outer surface and eliminating condensation at the source rather than mopping it up after the fact. The two-part construction makes fitting and removal straightforward without disconnecting cooling lines or disturbing the fermenter, and the SBR foam wipes clean easily or tolerates a cool machine wash between batches.

A small but targeted accessory that solves a specific and genuinely frustrating problem — if you are running a GF30 with glycol cooling in a warm climate and fighting condensation, this coat is the clean, permanent fix.
