Every product from the sections above, listed once. Sort by the criterion you care about most, or tick up to three to compare.
The 16 gallon version of the BREWSIE kettle, with false bottom, dual filtration, thermometer and valve for larger or full-volume batches.
Fit for the job 9/10 · Features and specs 9/10 · Build and materials 8/10 · Value 8/10
- + 16 gallon capacity handles full-volume all grain boils and bigger batch sizes without boilovers
- + Same false bottom and filter setup as the smaller BREWSIE, so draining stays clean at scale
- + Thermometer and ball valve come fitted, so the kettle is ready to use as a mash tun or boil pot
- - A full 16 gallon pot needs a strong outdoor burner and will not boil well on a kitchen stove
- - Heavy and bulky when full, so moving it around the brew space takes care
Briess 2-Row Brewers Malt at 1.8L in a 10 lb bag, a clean, light base malt for all grain beers.
Fit for the job 9/10 · Features and specs 8/10 · Build and materials 8/10 · Value 9/10
- + 1.8L color keeps pale ales and lagers light and bright
- + Briess 2-Row is a dependable US base malt with strong enzyme power
- + 10 lb bag covers most of a five gallon batch base
- - Check whether the grain arrives crushed or whole before ordering

Fit for the job 9/10 · Features and specs 8/10 · Build and materials 8/10 · Value 8/10

- + 27.5 x 32.5 in size wraps over the rim of bigger pots so the bag stays put
- + Reusable mesh replaces a separate mash tun for simple all grain brewing
- - Check your kettle diameter, since a bag this big can bunch up in small pots
- - Handles add seams where grain bits can hide, so rinse thoroughly
BREWSIE's 8 gallon stainless kettle with a false bottom, dual filtration, thermometer and ball valve, sized for classic extract and small BIAB batches.
Fit for the job 8/10 · Features and specs 9/10 · Build and materials 8/10 · Value 8/10
- + False bottom and dual filtration keep hop debris and grain out of the ball valve when draining
- + Built-in thermometer lets you watch mash and steep temperatures without a separate probe
- + 8 gallon size gives enough headroom for a full boil on a typical five gallon batch

A 10 lbs bag of crushed 2-Row brewers malt, the base grain for most all grain homebrew recipes.
Fit for the job 9/10 · Features and specs 7/10 · Build and materials 7/10 · Value 8/10
- + 2-Row is a versatile base malt for pale ales, IPAs and lagers
- + Pre-crushed grain is ready to mash without owning a grain mill
- + 10 lbs covers most of the base malt for a five gallon batch
- - Crushed grain goes stale faster, so brew within a few weeks

Bellamei's reusable 2 pack of 22x26 brew bags with 250 micron fine mesh and a drawstring for BIAB and hop straining.
Fit for the job 8/10 · Features and specs 8/10 · Build and materials 7/10 · Value 8/10
- + 250 micron mesh holds back fine grain particles for clearer wort
- + 2 pack gives you a spare or a second bag for hops and dry hopping
- + Drawstring closure lets you cinch the bag around the kettle rim
- - No handles, so lifting a full mash bag is awkward and can burn hands

- + Includes a filter tray, filter cylinder and filter bag for holding back grain and hop debris

Fit for the job 8/10 · Features and specs 7/10 · Build and materials 7/10 · Value 8/10

- - The brand is unknown and the listing gives no mesh gauge or wire detail beyond the micron figure.
Winco 18 inch solid basting spoon in 1.2 mm stainless steel with a hanging hole. Three inches shorter than the 21 inch spoons here, which suits small-batch and stovetop kettles.

- + Made from 1.2 mm thick stainless steel, described as built for daily commercial foodservice use
- + 18 inch length fits 1 to 3 gallon stovetop kettles where a 21 inch spoon is awkward
- + Hanging hole for storage, and the listing states it is dishwasher safe
- - At 18 inches it is short for deep 10 gallon and larger kettles, where a 21 or 24 inch tool reaches better
- - A general kitchen basting spoon, with no brewing-specific features such as a paddle head for mashing
Fermtech 24 inch mash paddle in 304 stainless steel with drilled holes and a hanging hook. Made for stirring grain in a mash rather than wort, and priced above the plain spoons here.
Fit for the job 8/10 · Features and specs 7/10 · Build and materials 8/10 · Value 7/10
- + Drilled holes let liquid pass through the blade, which the listing ties to easier stirring and mash efficiency
- + 24 inches long and made from 304 stainless steel, per the listing
- + Hanging hook for storage, and the listing calls it a good match for electric brewing systems
- - A flat paddle does not scoop or lift liquid, so extract brewers may still want a regular spoon

- + 2 LBS is a handy amount for blending into a larger base malt bill
- - 6-Row can add a grainy, husky flavor if used as the only base malt

Fit for the job 8/10 · Features and specs 6/10 · Build and materials 7/10 · Value 8/10
- + 21 inch overall length, the usual size for stirring 5 gallon extract and all-grain batches
- + Stainless steel is listed as the metal type, from an established foodservice supplier
- + Solid bowl, so it can lift and move liquid as well as stir, unlike a perforated spoon
- - Listing states there is no cool-touch handle, so the bare metal can get hot if left in the kettle
