Pressure Gauges – A Chat with Atlantic

So – I had a call from Atlantic. They’d had a read of my previous post. (Go on, go read it.)

Atlantic are a major installer of cellar kit in the south east and are responsible for some of the installs I’ve been having a grumble about. I had a conversation with a chap there who was remarkably civil in his defence of what they do. (Considering the scathing tone in what I wrote regarding UK cellar installs.)[1]

Amongst many points[2] discussed one seems key:

Atlantic do not fit gauges on regulators because the gauges on UK[3] regulators are crap. (Not a direct quote, but it captures the gist of things.)

Now… better gauges _are_ available, but they’re not the standard, and if it comes down to a choice between no gauges and gauges that are unreliable they’d rather leave the gauges out. Completely understandable – and I see where they’re coming from. It is a proper conundrum.

The better gauges? Very few folk getting quotes for installs want to pay more than whatever the rock-bottom pricing option is… BrewDog will, and the odd one or two other outfits in London. But elsewhere it comes down to offering a higher quote for a job that a competitor will simply undercut by offering cheaper “equivalent” equipment. (A comparison of £4000 versus £9000 was given, albeit I doubt that can be entirely about the gauges!)

Thing is, whilst I understand all that, I still don’t see this as being a “craft beer” quality of install. And I don’t believe a one-size-fits-all approach to PSI is “craft beer” ready.

I understand where Atlantic are coming from on this however and it sheds a lot of light on the situation.

Two other points are integral to thinking about keg pressures:

  1. The install without cooling for the kegs is fundamentally not “craft beer ready” either. I dislike seeing kegs as high as 12C, let alone ambient. This instability of temperature adds another variable that causes further requirements for pressure adjustments. The best I can do is not deliver too much beer at once, so such a place has only the kegs on plus limited reserves. (And ideally convince them to put kegs in some sort of cooler.)
  2. Many breweries basically haven’t a goddamn clue. They can’t even tell us what their vol CO2 levels are. This is a persistent problem, as per my “Summer of Fob” post. I’ve come across some seriously dangerous kegs.

In my view the way forward is three-fold:

  1. Breweries need to get their technical shit together and move away from this “craft beer” is “random WTF oh whoops!” beer… get vol CO2 _right_ for the beer you’re brewing, don’t keg it when there is plenty more secondary to go, stick the target vol CO2 on the keg label. If you can’t do that then bloody well sterilise it, before one of your kegs kills somebody.
  2. Breweries/Distrib/Pubs need to get their storage shit together. I’ve a 4C coldstore for keg now – in an effort to fight over-carbonation. Breweries ought to have the same. “Live” beers, especially ones with wilder yeasts, will almost certainly be able to attenuate further in the keg. Pubs are in a harder place here and the simple answer is: DON’T BLOODY STOCKPILE “CRAFT KEG” IN YOUR WARM (12C) CELLAR FOR WEEKS! (They do it just to bulk-order and save a few bob.)
  3. Breweries/Distrib need to be a _lot_ more hands-on, and a _lot_ more supportive. Standards need to be set for cellar installs, and guidance and support in using the kit needs to be offered. (If the UCB can do anything this might be it… not piss farting about trying to define and “protect” daft terminology.)

Step 3 is part of what I am trying to do with Jolly Good Beer. I’m not bloody DHL-for-beer – I don’t just lob kegs at you. Hell – I can check that your pressure gauges are not too far out and replace them if they are. I definitely will be now that I know they’re considered so unreliable. (My US ones are still reading fine and they get carted all over the shop rather than just being stuck to a wall.)

Anyway… there’s always food for thought available. My take on this is that leaving the gauges out because the standard gauges aren’t good enough is not good enough. But that’s perhaps not a role that Atlantic ought to be taking – unless the customer is willing to shell out for a fully supported system. I’m happy to, and able to, test pressures and help get beer pouring – breweries ought to be the same. And more than that, the vast majority of publicans need more knowledge and information, something we in the business of putting beer in their pubs should also be providing.

It’s what’s best for the beer.


[1] I’ve always thought the Atlantic installs look really well put together. And when I hear folk are getting Atlantic in I’ve said: ah, they do nice installs – just make sure you get pressure gauges. (And some subsequently have.)

[2] We also discussed and agreed that KeyKegs are great for getting around a huge part of the whole carbonation problem. All you need is “enough” pressure to keep whatever carbonation is in there in solution. Of course this would be easier if breweries weren’t so frequently over-carbing kegs. I’m so/so on KeyKegs – I think this is a strong point in their favour. But I still see a “proper” steel keg as the best option. Robust and reusable… but top-pressure becomes much more important with them. The problem with temperatures was also agreed on.

[3] It does make me wonder about the US kit a bit. The ganged Micromatic regulators I buy work out at a good price. They’re the “premium” model. Although they still have the usual non-liquid-filled gauges. I’ve always tested mine against reference pressure and never had a problem aside from a recent pair that seemed to have been damanged in transport.

Summer of Fob

50 PSI in KeyKeg

50 PSI in KeyKeg

Keg… in summer… in the UK… it is a fucking pain in the backside. Currently I am having a “summer of fob”. (“Fobbing” is what happens when a beer is too foamy to serve, “foam on beer”, there are several ways fobbing can occur – carb level, temp, flow rate…)

Keg is quickly becoming core to my distribution business. In fact I’m slowly moving to less and less cask volume and considering dropping cask entirely so I can focus more on keg and packaged beers. But there’s a problem with keg – I’m getting higher ullage rates, and an ullage is effectively eliminated sales volume, work done for nothing – and that hurts my small business. It strains relationships with pubs and breweries too. I’m sat here as the middle-man copping the flack from either side.

There are key problems that I believe the UK beer industry MUST solve:

  1. Breweries should not be releasing beers that will gain over 1 vol of CO2 outside of the brewery. Let alone 2 or 3 vols! Surely? Is that reasonable? I’ve handled kegs that are up at 6 vol CO2 (in steel thankfully) and had a KeyKeg at 4 vol CO2 recently. That is on the verge of a KeyKeg’s maximum PSI rating at room temperature. If that 6 vol CO2 beer was in KeyKeg it could very well explode at cellar temperature. If breweries do this it’ll only be a matter of time before a serious injury occurs. That could be in the brewery, could be in distribution, could be in the pub…
  2. Distribution should be keeping kegs cool. This is unpasteurised unfiltered beer folks, it _will_ continue to attenuate somewhat. If you leave your kegs lying around for a week at 20C in summer they’ll probably gain some CO2 and thus result in fobbing. Causing issues at the pub, causing bad vibes, ullaged kegs, and hassles for both distribution and the brewery. I have a 10C coldstore and I’m not happy with that, but many “craft” distributors don’t have a coldstore at all. Hell, too many _breweries_ in the UK don’t. My own goal is to have a 4C-max coldstore for keg and packaged beer products. Some think me a fool… perhaps I am. It certainly isn’t currently a competitive advantage in a market where pubs will do anything to save a fiver.
  3. Pubs need to learn more about keg beer. The BII ABCQ is pretty much a waste of time, someone interested in their job & beer quality will already know _more_. We need a UK-tailored equivalent to Cicerone. Not just that – but pubs need to _not_ buy 2+ months worth of keg stock at once and then leave it in their 12C cellar. See above point: it _will_ attenuate further, the CO2 will increase, you _will_ have more issues with fobby beer. Ideally I’d love to see pubs with keg cellars below 6C… I’m dreamin’ now… Not every beer will have it in it to go far enough to cause problems, but some will. Just do not buy and store kegs for this long unless you can keep them cold. That’s just plain good practice regardless.

I don’t think a pub ought to have to worry about knowing how to vent kegs to reduce CO2 levels – but whilst the above 3 problems remain unsolved the best alternative I can think of is that pubs need to learn how to do this. Yet the current status in the UK is that most don’t even know how to manage within-acceptable-bounds cases with pressure and flow control. The highest level of UK cellar training is the BII ABCQ and, frankly, it is barely even what I would consider sufficient as a  “new-joiner briefing” in a serious bar or pub. It’s crap, it’s designed for Wetherspoons and similar bar chains that have standardised products and support contracts.

I have _NEVER_ come across a keg I cannot get pouring. That 60 PSI steel keg I mentioned worked just fine after some venting, and the beer was actually pretty awesome. KeyKegs are even easier to vent.

Now… how do we fix this? <troll>Pasteurise all the keg beer?</troll>

(I have views on the lack of refrigeration in UK beer retail too… that’s one for another time though.)
