Brewing again – trying to solve the stuck fermentation problem

We haven’t brewed for a while. Since moving to all-grain brewing last year, we’ve had a couple of successes – a tasty mild and a blackberry wheatbeer, for example, as well as some drinkable if unremarkable bitters. However, we’ve suffered stuck fermentations in the last couple of brews, and it’s been rather depressing. All that effort, and you end up with sugary water.

(Note – a stuck fermentation is where it starts off fine, but stops fermenting before it reaches the expected final gravity. Final gravity should be around 25-30% of the original gravity. So our last brew had O.G of 1053, but only got down to 1025, i.e. 45%)

This has happened twice (and in fact, our third-from-last brew only got down to 35%), and we can’t understand why this has started happening – we’re not doing anything different with the yeast or aeration, which seem to be the usual culprits for stuck fermentation.

We consulted all our books, and searched the internet, and came up with the following theories (and counter-arguments).

Go to the Pembury Tavern beer festival

If you’re in London or within a train ride of London between now and Saturday, go to the Pembury Tavern beer festival in Hackney.

Stonch has kindly posted all the details here.

We can echo his recommendation for Cairngorm “Trade Winds” – it has a fantastic aroma (probably due to the elderflowers) and a complex finish. As they say.

We also loved Milton brewery’s Elysium – a very smoky stout. In fact, we loved almost all of the ten or so beers we tried. And they do good food too. Go on. What are you waiting for?

Meantime at Large?

This just in, courtesy of Marketing magazine: Adnams have just acquired the rights to distribute and sell Meantime draught beers in the UK, and the sales rights to all of their bottled beers.

I’m taking this as good news — if it means we start to see their London Porter or IPA in more pubs, I’ll be a very happy chap.

The same magazine also brings us news that German brewery Flensburger is launching a draft beer in the UK.

Ochakovo Brewery Pollution Scandal

baltic_mild.jpg

We posted enthusiastically on the subject of Ochakovo a few weeks ago, so this story from the Russian News and Information Agency caught my eye.

The Russian Ministry of Natural Resources and its watchdog accused Ochakovo of spilling unfiltered industrial sewage, possibly containing malt into the offshoots of the Moskva River in the west of the city in early July.

Mmmmm. Industrial sewage — with added malt. Gargle.

But that’s not the whole story. There’s a suggestion that there might be some corruption at the top of the Russian environment agency:

“We cannot consider the test results objective, knowing the originally prejudiced attitude by a senior environmental official against Ochakovo,” Yury Lobanov, vice president and chief engineer of the company, said in an apparent reference to Oleg Mitvol, deputy chief of the environmental regulator.

It’s a nice beer, but clearly pumping rubbish into the environment isn’t a good thing. Perhaps they could do to learn a few lesson from Adnams.

Adventures in Cornwall Part 2 – St Austell Brewery tour

Having had my socks knocked off by St Austell’s bottle-conditioned “Admiral’s Ale” (see previous post), I was determined to find out more about it. So I booked myself (and friend) onto their brewery tour on Friday afternoon.

Simon, our tour guide was very good and knowledgeable, and it was a very interesting and enjoyable tour (particularly given our recent forays into homebrewing). I particularly liked seeing the mix of old and new equipment in the brewery. During the tour I learnt that they consider one of their key ingredients to be their own source of water (I believe it comes from a well in the old family home) – a pure and steady source, filtered through limestone (just like in Burton).

My second-favourite part of the tour was seeing the microbrewery where the head brewer experiments with new brews – I reckon all that equipment would just about fit in the spare room…

My favourite part of the tour came with the session in the bar afterwards – as well as the obvious activity of trying the beers, a number of the brewing team were in the bar as well, including the Head Brewer, Roger Ryman. Being the roving reporter that I am, I obviously took full opportunity to have a chat about some of the interesting brews that St Austell have been producing.

cloudedyellow.gifFirstly, I asked about Clouded Yellow, a bottle-conditioned wheatbeer that manages to pull off many of the main flavours of a Bavarian hefeweizen, while remaining unquestionably an ale. Roger explained that they use their standard yeast (so as not to risk contamination from the rather wilder Bavarian strain) but recreate the flavour using spices and vanilla.

It’s a very interesting flavour – possibly not to everyone’s taste, but I’m a fan, particularly when it’s slightly chilled, with the yeast shaken in. I also think it’s great that St Austell is willing to experiment with a beer like this.

Then I asked about the Admiral’s Ale, which I had been truly amazed by. The “secret” to this (not too much of a secret, it’s on the label!) is the malt that’s used.

The standard way that colour is added to beer is to brew with a pale malt base with a little crystal malt, or other dark malts, or roast barley. (The longer you roast the malt, the less fermentable sugars you get and it becomes expensive or indeed impossible to get fermentable wort).

For Admiral’s Ale, the brewery uses 100% “Cornish Gold” malt, which is kilned for a little bit longer than standard pale malt – not long enough so that it loses its yield, but enough to add colour and flavour.

Back to the bar, I sampled the other products I hadn’t seen. Cornish Cream is their take on the Guinness market, described as a “dark smooth ale”, and is slightly sweet. Possibly a good first step to weaning people off Guinness?

freebeer.gifSt Austell have also just launched “Freebeer 3.2”, which will be on sale at the various Tate Galleries across Britain. This project is worthy of a blog post in its own right – the recipe and branding of FREE BEER is published under a Creative Commons license (Attribution-ShareAlike2.5). This gives permission for anyone to use the recipe or create a derivative to brew their own FREE BEER and to use the design and branding. For more on Freebeer, see this link.

St Austell has considerable regional dominance (over 150 pubs, the vast majority in Cornwall), and also, interestingly enough, only makes around 20% of their turnover from beer (the rest comes from wines and spirits wholesale and retail). Given this, they may have been tempted to skimp on the quality of the beer. Instead, there’s innovation and experimentation – great to see.

Boak

1. The St Austell brewery is in the centre of St Austell, Cornwall. There is a small museum in the Visitors’ Centre, where the tour starts. They seem to be running a lot of tours at the moment, but appreciate a phone call before you turn up.

2. If you’re staying in St Austell, I recommend the B&B I stayed at – Topos. It’s about 10-15 minutes walk from the station (and brewery!)

3. Since my visit, I’ve subsequently found out that Roger Ryman was awarded “Brewer of the Year” by British Guild of Beer Writers in Dec 2006. So I’m by no means the first to praise St Austell’s innovation!
