Simple Filter for Brewing





Introduction: Simple Filter for Brewing

Home brewing beer is a great hobby - once you've got the equipment, you can churn out personalised, delicious craft beers for half the price of bottled ales from the supermarket, or a third, even a quarter of pub prices.

Last time I brewed a batch, I had trouble filtering the hops from the mash before I added the yeast. I had to employ an extra pair of hands to hold the filter.

This time*, my helper was busy with homework, so I decided to sacrifice some kitchenware to create a filter holder.

Step 1: What You Need...

This is a really simple project - all you need is a cheap plastic jug and a drill.

Step 2: The Make

Er... drill a load of holes in the bottom of the jug. That's it.

However, you need to be careful, because the bottom of my jug turned out to be quite brittle, possibly due to age. This means I ended up with an untidy, cracked mess of a jug. This is OK for me, but if I was making one for a friend, I might use a smaller bit and take more time drilling.

Once the loose scraps of plastic were cleaned off with a small knife, all I needed to do was put the filter bag inside the jug, and I was ready.

Step 3: Using and Modifying

I used this filter holder twice in the same brew.

It worked well, I held the filter in one hand, and scooped the hop-laden mash from the pan with another jug. But the hops held on to the liquid, and drainage took a while, so before I used it again, I grabbed a pair of shears and cut a gap in the bottom of the handle.

This meant I could hang the filter on the side of the brew barrel, and (carefully) use both hands to pour the wort directly from the pan into the filter, then leave the filter to drain into the barrel while I got on with cleaning and tidying up.


The perforated jug is now sitting in my brewing cupboard, with the cleaned filter folded inside, ready for next time.

    Why not use a hop sock? Or a strainer that fits on top of the bucket?

    I make homemade wine and I found that you can make your own filter bag as well. It can made out of sheer curtain material from a fabric store, an old pair of sheer curtains that you don't use anymore, or a pair from the thrift store would work great at very little cost. Make your own pattern on paper and then cut out two pieces by folding the material and pinning the pattern to it. If you feel really inspired even make a channel for a drawstring at the top when you sew it up. Just take a measuring tape and get the circumference of your bucket then add about 2 more inches to it so that you can slip it over the top the bucket and allow for 1/2in. seams Half of that measurement will be the top of the bag on your pattern. Measure the depth of the bucket and add about 5 extra inches. That will give you 1/2 in. for the bottom seam and to turn that seam up one more time, and sew it, for extra strength, the balance of the material allows for the top of the bag to be turned down into a 1/2 in seam or a little larger if you want to add a drawstring in the top, it also leaves extra inches to hang over the top of the bucket so you can pour ingredients in without it falling into the bucket. I made mine to decrease in at the bottom of the bag by making each side slim down to 3inches less on each side than the top measurement. That allows for the juice to have room around the bag, if you stir it the first week. I sanitize the bag along with all my other impliments prior to starting to make my wine, the nylon curtain material doesn't seem to absorb the fruit or stains like cotton does, so it rinses clean quickly. Another plus is that you can just snap down the lid to the bucket over it, and because the material is so sheer it takes up almost no space. The material is also very strong so you can really sweeze it hard to get out the juices when the time comes to remove the must.

    You really think so? I didn't take any photos when I made mine though. I guess that I could fake it by taking pics of measuring and making a new pattern etc. Then show the finished bag in a photo. What do you think?

    Worth a try, or you could make a whole new one for a spare, or as a gift for a fellow wine-maker?

    I made an instructable on Adapted Inmate wine - I don't know if you can make more than one entry or not in the contest. Either way it's okay - I just wanted to share the how tos with everyone so they can make wine easily and cheaply. lol Maybe I'll make one on the bag later just for fun if there is a limit to entries to the contest. Good luck on your entry.

    Thanks, They may not even accept the one that I submitted as the email that they sent me says if you don't hear back in one day that means you didn't meet the contest requirments. I submitted it last night and haven't heard anything as yet about it being accepted. Maybe it wasn't good enough. I should know for sure by tomorrow. Just have to wait and see. At any rate - I'm going to enjoy some of that wine and not worry about it. lol Good luck with yours - I voted for you.

    I forgot to add that I really liked the idea of clipping the handle to make it slip over the top of the bucket too. You could also use a souldering iron to burn the holes into your strainer that you made. That would allow you to control the size of your hole, and it might not mess up the bottom even if it was brittle from age. Just a thought. Great job.

    Hello! How would you recommend sanitizing the filter if it's done post-boil? Just dip it in StarSan?

    I just soaked it in a jug of hot water with a generic chlorine-based sterilising powder dissolved in it.
