LD Carlson 4718 Brew-in-A-Bag Straining Bag with Handles (24x26) Review (2026)

Material and mesh size

This bag is made from USDA food grade nylon with a mesh rated at 600 microns, fine enough to hold back crushed grain husks and particles during a brew-in-a-bag mash while still letting wort flow through freely during the steep and drain. Nylon mesh bags like this one are washable and reusable across many brew sessions, unlike single-use paper or cloth alternatives, which makes the per-batch cost drop quickly for anyone brewing regularly. LD Carlson is a long-standing wholesale supplier to the homebrew industry, so consistent manufacturing quality across mesh bags with this specification is more likely than with an unbranded generic bag.

Size and handles

At 24 by 26 inches, this bag is sized to steep grain directly inside a kettle and be lifted back out once the mash or steep is finished, rather than needing to be strained through a separate colander. Four handles are sewn onto the bag, giving multiple grip points for lifting a bag heavy with saturated grain, which spreads the weight across more than one hand or one lifting point and reduces strain on any single seam. Having four handles rather than one or two also makes it easier for a second person to help lift a particularly large or heavy grain bill out of the kettle.

Strength rating

LD Carlson rates this bag at 50 pounds of bursting strength, a figure meant to reflect how much weight and pressure the seams and mesh can take before failing, which matters most in the moment a fully saturated bag of grain, heavy with absorbed wort, is lifted clear of the liquid. A soaked grain bag can weigh considerably more than the dry grain that went into it, so a bursting strength rating gives a sense of margin for larger grain bills. Even with a solid strength rating, handling the bag carefully during the lift, rather than yanking it upward quickly, reduces stress on any one point of the seams.

Fit with common kettles

This 24 by 26 inch size is built to fit typical 5 gallon homebrew kettles used for brew-in-a-bag mashing, where the bag lines the inside of the pot before grain and water go in together. Very wide diameter kettles or unusually tall kettles can be a tighter fit, since the bag needs enough extra material to drape over the rim and still leave room for grain to circulate freely during the mash. Brewers working with kettles well outside the standard 5 gallon range, either much smaller or considerably larger, should check their own kettle's dimensions against the bag's flat size before assuming a good fit.

Who should buy it

This bag suits homebrewers doing brew-in-a-bag mashing in a standard size kettle who want a reusable, food grade nylon bag with multiple handles for a secure lift. Its 600 micron mesh and 50 pound bursting rating make it a solid match for regular use across many brew days rather than a single-batch product. It is a less certain fit for brewers with unusually wide or tall kettles who should confirm the bag drapes properly before their first mash, and anyone brewing very frequently may want a spare bag on hand, since a single bag with no backup means a tear could stall a scheduled brew day.
