Post Brewlab Beer

It's been a month since I set off for windswept Sunderland to learn how to make my beer a little bit better. A whole month! Seems like only yesterday. Having said that, it's lucky they sent us home with the notes, as there was too much information for 20 drinkers to completely absorb.

If you have a wort chiller, the next bit doesn't apply!

The main issue for me is DMS (Dimethylsulphide), which is a taste/aroma compound which makes the beer taste and smell of cabbage, or overcooked sweetcorn. It can be present in small amounts and affect people's drinking pleasure differently. For me, though, not nice. So, after brewlab, have I got rid of it?

Well, in short, so far, yes! And thank God too, because it was ruining my beer. It was all about the cooling. The precursor to DMS compounds can be found in malted barley, and aggravated into existence during mashing, but then evaporated during a long rolling boil, to below noticeable amounts. Which is great. No problems then.

The DMS compounds continue to form, however, as the wort cools down, and longer cooling periods, as used by myself with no way of chilling the wort, can bring the levels of DMS back up to really  noticeable levels! So, although I don't have a cooling coil yet, it's on the list. I did, though, manage to maneuver the hot copper into a sink with cold water, which made short work of bringing the temperature down to about 60oc. Now we'll have to see after fermentation is complete if that was enough!

The recipe was for my usual Golden ale, which means that in spite of all the hops, there's no room to hide any unruly smells.

No pictures with this one, as I couldn't take a picture of the smell. Maybe in another couple of years.

Brewlab Education

And it's back to college for a few days!

I've been booked on the course since June, but I never thought it'd come around. But now I'm here, I can't believe I'm already halfway through! I've just finished the second day of the 3 day plus one Startup Brewery course at Brewlab Ltd, and it's basically sorted out all of my problems, from mash efficiency to those funny off-aromas, without even bothering to try one of my beers!

Firstly, the course took twenty of us (some home brewers, some not), through the brewing process from start to finish, and funny enough, they started with the brewing liquor, or water-what-you-make-beer-with, starting with the treatments in order to keep the beer in character and style with the original, and also in order to increase the mash efficiency, by adjusting the pH of the liquor. So that's the first thing I'll need, some litmus paper.

Then Arthur took us through the recipe compilation, using the ^ol scale, which measure's the malts potential extract, and will more than likely lead to much more accurate predictions of O.G., or the amount of fermentable sugar I can expect in my wort (pronounced wert, apparently, even in a thick Geordie accent). Out with Imperial, in with Metric. Sigh.

Arthur also casually pointed out that my DMS problem (smells like teen bedroom) comes from not chilling the wort quickly enough (or at all, in my case, as I usually let it cool down over a period of hours). Unpicking my brewing experience with one casual casual question: how do you cool down your wort?

The rest, all equally important, but numerous, will all be addressed soon. Some will be addressed at relatively little expense, some will likely cost more. Dr Thomas advocated getting a little more familiar, if not downright voyerstic, with yeast. Buy a microscope. I think Santa will be busy picking through 400x magnification Haemotologists microscopes in the Argos catalogue this month!

So, two more days to go, so much to learn, and so little time. You can see some gaps in your knowledge fill up, while watching others burst open, as you realise how much there is yet to learn! Early to bed tonight then... well, I'll just 'sample' this one more pint!
