How to make 20,000 pints of beer.

There are several projects here for small-scale home brewing.

I thought I'd find out how they do it properly.

I turned to the Adnams Brewery, and enlisted the help of their Quality Manager, Belinda Jennings, who I first met in a field in Suffolk...

Step 1: Raw materials

The thing about brewing is that there are no secret ingredients.

Water, malt, hops, yeast.  That's it, for a proper beer.

What affects the final flavour is the way these things are treated.

The softness of the water, how dark the malt is roast, the species of hop, the strain of yeast.

Malt adds sweetness, and provides the sugar for fermentation.  Hops add bitterness, especially to balance the sweetness of the malt, and the yeast, of course, turns the sugar into alcohol.

Most brewers (Adnams included) will happily give their recipes, but they won't give their yeast - established brewers have strains that are slightly different to other brewers' strains, and so affect the flavours.  Adnams have been using the same strain of yeast since 1945.



Step 2: Preparation and control.

Malt must be milled, yeast grown and water boiled.

The remains of the milled malt go to be animal bedding - very little of anything is actually thrown away by Adnams.

In 2008, Adnams installed a whole new brew-house.  As well as being highly controllable and automated (in-line systems weigh out ingredients instead of sacks having to hefted in by hand), it also recycles the waste steam from the brewing process - it saves 30% on energy costs, but it also means that the brewery doesn't smell of brewing, which is a shame IMO.

Step 3: Wort.

The milled malt is heated and stirred (mashed) with water in the lauter tun, for 90 minutes.  This dissolves the sugars and other flavours out of the solid malt, making a liquid called wort.

The heating pattern - how hot, how long, when the temperature is changed etc - affects how much of what flavours are dissolved out of the malt, and will affect the final flavour.

When the wort is transferred to the next tun, the solids are left behind, eventually to end up as cattle feed.

That's cool. Did you do this for a class project, or just for fun?
Kiteman (author)  Yard Sale Dale12 months ago
Ha, just for fun and personal interest.

So, the abbreviated guide would be something like....

1)Obtain brewery
2)Brew beer
3)repeat until 20,000 pints have been accumulated.
4)???????
5)profit.

what the heck are kirkins i thought they were kegs!!! :S
If you mean firkin, it's roughly 41 liters or one quarter barrel. Also one sixth of a hogshead. (I hope I recalled those correctly) Firkin is actually the measurement and thus a common name for the container that holds said amount. Mmmm...Beer! Thanks for this one Kiteman.

Very nice report (not a instructable imho...) I made at least 40000 (imperial) pints in my life, but it took me ten years ;-) Last year, our "brewery" had it's 10. annyversary. So we wipped up a little party. It was so well received, we had to repeat it this year. With some special food and enough beer. Some pics of it: http://www.instructables.com/id/Bierfest-at-the-brewery/ also not an instructable in it's pure form, just bragging...

 Fantastic! It's a shame you couldn't see the pasteurisation process, or indeed document canning / bottling. Quite interesting!

I toured the Fosters brewery in Manchester many moons ago, and they are interesting places. (That brewery smell is fantastic, isn't it!)

The problem with many factories (or at least the industry I am in) is that most of the process is in sealed tanks, pipes, etc, so you only ever see the final product.


the canning process is pretty simple i can explain if you want me to?
Kiteman (author)  solo.card4 years ago
Adnams don't pasteurise their beer - it's all as real as it gets.

Fosters?  Sorry, that's lager, not beer... ;-)

Fyi on a small error

quote "which is more than the AA would do, despite me being a member for twenty-five this December!"

i believe you forgot an a and years.
dont mean to be a critic btw just being helpful
P.S. when i first saw this i thought you were going to make 20,000 pints of beer at home......
keep up the great work!
Kiteman (author)  xproplayer5 years ago
I didn't forget an A (I live in the UK), but I did forget the years...
Just out of interest, Kiteman, which AA would that be? ;¬)
The one most probably running your TV remote.
Kiteman (author)  AndyGadget5 years ago
The one that is supposed to collect drivers from fields, not from breweries...
Oh.....  My cousin likes to say he's the founder of AU.

At least he didn't start a face book group known only as F.U.G.U. (I did...)

i dont think they would pick you up from a brewery they would probaly think your a drunk and dont deserve to be towed......

no offense just a joke
i never noticed before but congrats on 100 'ibles

Very nice instructable Kiteman, and you beat me to the punch!  I was talking to my little brother the other day about doing an instructable a lot like this--he's head brewer at a microbrewery here in Oregon.  I think yours is probably better than mine would have been though, as his operation is quite a bit smaller scale than that of these folks and I'm not sure my writing chops are up to par with yours.  Thanks for sharing your visit to this historic brewery!
Kiteman (author)  depotdevoid4 years ago
Hey, go for it anyway - readers will be more able to replicate a microbrewing project than one on this scale, and your brother doubtless uses slightly different ingredients and processes.

As for the writing, practice makes perfect.

A field in Suffolk you say? kiteman, what a dog you!
 What a milestone! 100 instructables! TimAnderson has double that, but you still have significantly more instructables than most of us.

I visited a few vineyards in both canada and germany, but this was extraordinary!
Kiteman (author)  MrMystery965 years ago
Thank you!
KnexFreek5 years ago
I will make some tonight. Thankyou.

(jk im 13)
If you ever find yerself in Chattanooga  Tennessee ,   look up th' Big Bend Brewery !  It is a microbrewery/pub that serves up some of th' best "specialty" beers and ales I can remember drinkin'  ( stop snickerin' dang it ,  you know what I mean !!  )

Good job!  I've toured a few winerys, but haven't gotten to tour a proper brewery yet.  I'll try to make it a point on my next vacation.
PKTraceur5 years ago
Very interesting 'ible Kiteman!
clark5 years ago
 wow! really neat!
Kiteman (author)  clark5 years ago
And that was a fast comment!
and a fast reply in the same exact minute!
Very cool.  I like to make my homebrew, and it's interesting to see on a larger scale.

I live in Golden, Colorado, where they make Coors.  It's definitely not my favorite beer, but on the brewery tour they claim that their copper kettles produce less of a metallic taste.  Do you know any of the reasons why Adnams would use stainless steel rather than copper for the new vats?

Yeah, copper costs like gold these days, and junkie would probably break in to steal the copper.
and maybe some beer too?
maybe something with sanitation? i know that all doctors stuff is all stainless steel.
One of the main reasons may be that SS is way easier to clean and sanitize than copper.  Not sure how it effects the flavor, but copper naturally forms a thin copper oxide layer which is dissolved into the beer by the acidic wort.  Copper reacts badly to some cleaning agents (like bleach) causing larger than usual copper oxide deposits, which when dissolved into the wort can cause serious problems.
Kiteman (author)  tashiandmo5 years ago
That is the reason - far easier to keep clean.

The new vats have no riveted joints, nowhere for bacteria to lurk, which is important when the end product does not get pasteurised.

Great idea doing a tour of somewhere and making it an instructable !
really interesting to see how they go about making beer, and seeing the technology they use.
Thanks !!
t.rohner5 years ago
Although this isn't a instructable in it's pure sense, i enjoyed reading it.
You have thoroughly researched all aspects of brewing.
By the way, i have brewed 40'000 pints of beer and ale over the last 10 years...

Cheers
Nice! My family and I make some pretty good beer at home.

Adnams is surely one of the best brewers. It rates right up there in my all time favourites.  I used to live in Diss and would make regular visits to the coast to stock my Adnams supply direct from the source.

There is a tiny little pub in Bungay called the green dragon that brews it's own beer, well worth a taste if you are in the area. www.beerintheevening.com/pubs/s/20/20954/Green_Dragon/Bungay

Another favourite of mine was St Peters. Did a really nice cranberry beer and a gorgeous old hall to enjoy it in. www.stpetersbrewery.co.uk/
