## Overview

The Brew in a Bag BIAB mash bag is designed for home brewers using pots up to 40cm in diameter. Made from durable polyester, it features strong reinforcing straps, double-stitched seams, and two lifting handles for easy grain removal. Lightweight at just 110g, it's also machine washable for effortless cleaning.

## Description

This mashing bag is for home brew beer using the BIAB (Brew in a Bag) method. This strong bag is reinforced all around with polyester webbing. This is stitched into the mesh around the top, down the sides and along the bottom of the bag to give excellent lifting strength. The dimensions of the bag have been determined so that they fit a typical 40 Litre boiling pot commonly used by home brewers.. The bag itself is 62cm (40cm dia) wide and approx 72cm deep so there is plenty to fold over the top of the boiling pot, and down past the handles. Two strong handles are provided for lifting the bag out of the wort. Ideally one would have a hook position above the boiler and hang the bag on that to allow it to drain. The bag is strong enough to take a large grain bill when wet, which could easily be 15Kgs and have been tested at 37Kgs load without problem (see picture). I use one of these bags myself for a wide range of brews.

## Features

- For pots up to 40cm in diameter
- Strong reinforcing straps, sewn into the bag along all seams, with 2 row stitching.
- Two integral lifting handles for lifting the grain from the pot

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great mash bag
*by J***5 on 10 November 2022*

the mash bag is really sturdy and has no trouble holding up hot mash while its draining. good size loops to lift the bag out with. easy to clean with a garden hose

### ⭐ Does not fit 40cm pots
*by D***S on 14 June 2025*

This does not fit 40cm pots. The circumference of the bag is 120cm which would at most fit a 35cm pot.

### ⭐⭐⭐ Good size, not strong enough
*by P***Y on 13 May 2023*

I purchased this as it has decent looking handles and looked large enough to fit me 55L pot.It did fit and the handles are great.However, upon pulling the bag up for the first time it ripped after getting caught on the temperature probes’ thermowell (which is NOT sharp, it is rounded and soft).Not a great start to the product which unfortunately is now useless as it has a hole in it.Overall fairly disappointed.
