FDA 21 CFR Homebrew Hop Spider & Mash Filter Specifications

A tall stainless steel mesh hop spider hanging from the rim of a large brewing kettle by three legs, steam rising

Homebrew Hop Spider & Mash Filter is used for containing hop pellets in the kettle and grain in the mash tun so wort flows clear into the fermenter. FDA 21 CFR is the reference cited for it on drawings, datasheets and purchase orders.

What FDA 21 CFR Means for Homebrew Hop Spider & Mash Filter

The dimensions in the table below are supplied to suit FDA 21 CFR. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.

Specifying Homebrew Hop Spider & Mash Filter Beyond the Standard

  • Diameter & length: Size to the kettle depth so the spider basket sits below the wort line.
  • Micron rating: 300 µm for boil hops; 150 µm for dry hopping to keep debris out of the fermenter.
  • Mount: Tri-leg rim mount for kettles; lid hook for fermenters.

When Homebrew Hop Spider & Mash Filter Is Not the Right Choice

Not a substitute for a plate chiller strainer or fermenter filtration when brite-tank clarity is required.

Frequently Asked Questions

Can a false bottom replace a mash bag?

Yes — a perforated stainless false bottom supports the grain bed and lets wort run off clear.

Does a hop spider reduce IBU?

Slightly, because hops circulate less; use a larger basket or add a few percent more hops.
