Collection: Homebrewing Accessories & Tools

Most accessories here are designed to work across the Grainfather range, but a few, like connection kits or filters, are sized for a specific model such as the G30, G40 or G70. Check the product details before adding it to your cart if you're unsure which system you own, or reach out to our customer service to confirm.

An overflow filter sits in your kettle's overflow outlet to stop hops, grain, or trub from clogging the line during the boil or transfer. It's a low-cost addition that prevents one of the most common beginner brew day problems, so it's worth adding if your system doesn't already include one.

Start with the essentials, a stirring paddle and sanitiser, then add speciality accessories as you find a specific need. We recommend buying further accessories as the need for them comes up, so you end up with equipment that suits the way you brew and makes brew day easier as your confidence grows.

Most of our accessories are built to last, but how long each one lasts depends on the materials it's made from. Items that touch heat or hot liquid, such as silicone tubing, gaskets and filters, degrade faster than rigid plastic or stainless parts and are worth checking each season. Replacing these before they fail avoids interruptions mid-brew day.

This collection currently features Mangrove Jack's hop spider, a mesh brewing accessory for adding loose hops without them scattering through your kettle or fermenter. Check back as the range may expand to include Mangrove Jack's yeast and kit products over time.

A hop spider is a fine mesh basket that hangs in your kettle or fermenter, holding loose hop pellets or whole cone hops so they infuse without loose material clogging your chiller or transfer line. It's a simple way to hop without extra filtering steps afterward.

No. A hop spider isn't used for dry hopping.

The Mangrove Jack's hop spider is designed to hang over standard kettle and fermenter rims, fitting most Grainfather systems. Check the product's listed dimensions against your vessel's rim diameter.

There can be a small reduction in utilisation since the mesh limits full contact between hops and wort, but most home brewers find the easier cleanup and clog-free transfer outweigh the minor efficiency trade-off. Adjust hop quantities slightly upward if you want to match loose-hop utilisation exactly.

Pre-crushed grain works fine for most home brewers, but milling your own grain just before brewing improves freshness and lets you fine-tune your crush for better mash efficiency. A mill becomes worthwhile once you're brewing regularly or chasing more consistent results.

A finer crush exposes more surface area to your mash water, extracting more fermentable sugar, but too fine a crush can cause a stuck mash by clogging your lauter system. The right crush balances efficiency against a clean, flowing runoff.

Most grain mills adjust crush width through the grain plate gap, either by a dial or spacer setting, so you can tighten it for a finer crush or widen it for a coarser one. Start with the manufacturer's recommended setting and adjust based on how your mash runs.

Freshly milled grain retains more aroma and flavour compounds than grain milled days or weeks earlier, since crushed grain oxidises faster than whole kernels. Milling on brew day gives the best flavour outcome if you have the time.

Yes, these grain mills are designed to feed directly into Grainfather all-grain systems, letting you mill straight into your mash basket without an extra transfer step.
