One Gallon Brewery

Post by gdanby » Mon Aug 16, 2010 4:44 pm

Hi to all - been watching years, but not posted much before this... :D

I have to admit getting a little disillusioned with brewing last year - I was starting to experiment with recipes and too many turned out different to be pretty bland. 5 gallons is a lot to drink when you know you can do a lot better. I was also getting short on spare brewing time, so I even considered selling my 10 gallon setup, until I had the idea of creating:

My new 1 gallon 3-tier brewery! I know this may seem strange to a lot of people, but let me put forward the positives:
  • My brewday now lasts a mere 2.5 hours (60min mash and 60min boil) from start to finish.
    Cleaning only takes minutes afterwards.
    I can brew 4 recipes in 4 nights using some of the same yeast starter.
    Each brew fits nicely into a demijon to ferment, then its only a case of washing and filling 8 bottles at a time.
The HLT is a 1 gallon plastic fermenting bucket with a kettle element. This will heat 5l of water to 82C in about 12 minutes.

The mash tun is a stainless steel stock pot (sold as part of a 3 part set from ebay for £14). A simple fixed sparge pipe has been fitted in the lid, fed by the HLT. The outlet was constructed using the mesh from a steel sieve from Asda:

The boiler is the larger 8l stock pot from the set with a slotted 15mm pipe outlet, powered by a burner on the gas stove:

I created a mini IC to fit into the boiler from 10mm copper, this cools the wort down to pitching temperature in about 5 minutes flat (with some frantic stirring!):

I've used this setup 8 times now (initially comparing US05 against Nottingham yeast) and I must admit its put the fun right back into brewing for me. The main advantage for me is the ability to play with recipes, knowing that if one turns out awful, its not too much time and money lost. I think this will come into its own when I harvest my Challenger hops again this year - so I can vary the bitterness across several brews. Typical though, all the brews have turned out good so far, so it's going to be a difficult choice to know which one to choose for a full batch !

Granville, I love it! It looks the part. Great idea if you're into experimenting. Will do something like this in the future.

What a fantastic little brewery. Top stuff.

Great idea!

Impressive brew times there, too. I'm upscaling at the mo, but that'll probably make experimenting more tedious - having seen this maybe I'll keep my old setup and downscale it as well!

Cheers

You clever, clever b@st@rd. I wish I'd thought of that!

top stuff. I have been planning on doing a load of 1 gallon brews to compare hops and yeasts etc, I even bought a set of 4 stock pots to do it in, hadn't thought of making a mini brewery to do the mashing as well - I was planning on mashing in my normal mashtun and then splitting the wort but this looks more convenient and much shorter. Think I might have to sort out the DIY stuff and see if I can make something similar this weekend. Thanks for the inspiration

brilliant stuff, I consider a 12 to 15 litre batch small enough to experiment with, but hats off to your cracking little idea :)

Brilliant idea and a very cute looking setup :) It's definitely one for my to-do list now. Do you have to be quite precise with the quantities of ingredients with a 1 gallon brew?

Granville, well can't you tell you've been lurking on here for some time!! - a very professional minature set up indeed - well done.
In fact I think this would suit beginners getting into all grain brewing far better than a potentially dangerous electric set up, without being overly costly. If it could be made "stackable" i.e. each pot - with its valve being able to stack into each other, including the FV and IC; and a collapsable 3 tier platform then someone could make a fortune selling them as kits.

Absolutely Brilliant =D>

If somebody marketted them, I would certainly consider one =P~
Well Done. :D

Thats one of the downsides, with high alpha acid hops! My last recipe was an Amorillo pale ale which required 4g of 9.6% Amorillo hops. The difference between 4g and 5g of hops was probably around 4 IBU !

The other things I've noticed is that the mash tun gives very good efficiency (yet to be worked out), but does lose 2-3C over 60 minutes. Theres also a lot of evaporation from the boil - I reckon on about 15% over the hour.

I wish I'd kept the photo of my fermentation cupboard with 5 demijons in, all of different ales, all bubbling away....

I like the idea of that ! Most of the parts for this mini brewery were recycled, but I reckon you could build this for under £80.

My original idea was about creating a youtube video showing how you can brew a gallon of real ale just using pots and pans already in the kitchen without any modification. The mash/lauter tun was going to be based around a colinder !

Gret stuff, very helpful. Which section of Asda did you find the steel mesh in? I`ve been looking for a short piece for my coolbox mash tun.

Wow, just wow! :shock:

What a fantastic, yet simple idea...I love the concept and the simplicity of it.

Fantastic way of experimenting, especially with some of the more weird and wonderful stuff, without wasting loads of ingredients, time and money if it ends up tasting like fermented dishwater!

If somebody does manufacture something along these lines, I'd be very interested - and if not I may have to try to build one myself. :)

Just from a sieve in the cookware which was £2.50 I think. When you cut it out and stretch it, it's actually quite square. The mesh is quite fine and I had one stuck sparge when I used the dregs out of the large sack of pale malt, but thats probably because the grist resembled more like powdered porridge than grain. I've just been to Wilko's and bought another metal sieve for £1.50, though the mesh isn't quite as fine. Trouble is with WIlko's, you always see other things you could use in brewing - I came out with a stainless steel tea container for £3 which I'm going to try to turn into a hopback for my larger brewery. Thats another project to keep me busy...

Just wanted to say thanks for all the great comments :D
