Filter - between fermenter and keg?

[Ralph]

Does anyone know of an inexpensive filter I could use between my fermenter and my keg? Often there has been some dry hopping and I would just be keen on something that would take out the hop particles. I don't have a pump so it is currently just a gravity feed.

Any ideas?

What about experimenting with either paper coffee filters or one of those super fine BIAB bags - I use one of those to filter out the break after the boil and it traps enough for it to start forming its own filter - not sure if that will work for your situation though.

You've probably already tried it but what about isinglass - It uses electrical attraction to drop yeast out so it might work for hops.

I have a small swiss voile bag about 150mm x 150mm with a drawstring which I attach to the keg end of my transfer hose. The other end goes onto the fermenter tap and it catches most of the hop bits. The bag end is tied tighly to the hose but the bag is quite baggy - if you put it on too tight against the hose it can block up.

 

I sanitise it with the hoses.

 

The only time I had an issue was when I used this setup for racking to a bottling bucket which I bulk primed - the sugars weren't stirred up well. Not an issue with racking to a keg though.

Try a soap-less stainless steel scrubby.

You can boil it to sterilise it first.

interesting... if it was stainless it should work fine...

Anyway I was just over at mitre 10... and you can get inline hose filters for irrigation setups with 13mm barbs for $10 so I bought one. Is all plastic and I would not use with hot wort, but from fermentor to keg it should work fine so I bought one.

Or just dry hop in a stocking or hop bag.

[Ralph]

yeh... that would be the other way to do it... ;-)

[Druid]

That's the way I do it - but I must admit I'm always wondering whether I'm not extracting enough hoppy goodness from that awesome smelling green stool I remove from my fermenter...

I use one of these. The are fairly cheap.

This really saved my bacon recently when I decided to dry hop in the keg, and upon removing the strainer bag a lot of granules ended up staying in the keg.

At morebeer they are around $49 USD. At the LHBS in Wellington it is about $100 for filter and hardware. (A little dear) I reckon there are probably water filters or such that can be used as long as they are sterilized.

I have always wondered about those, how often do you need to replace the filter in it and are the washable?
