Dark Mild with Invert #3

I almost always use dry yeast, but one of my perennial problems is getting enough yeast character in native beers. I have tried using sugars in the brew and pitching less yeast to increase ester production, but ultimately I wanted to try some new strains, specifically the Fullers strain, wlp002. In Portsmouth, where I'm from, there are loads of Fullers pubs, and London Pride is probably what I first started drinking at pubs. I like low attenuating beers, and also clear beers, and since this strain flocculates extremely well and is a low attenuator I thought it was ideal.

My previous efforts with (wet?) yeast have been disastrous. One was infected and both were phenolic. These were both early brews and I thought I might venture out again, hoping my technique had improved.

I wanted a dark chocolaty mild.  This time I wanted to use no crystal malt, even though I think people are unnecessarily afraid of crystal malt, especially in a beer like a mild where you want it to be a bit smooth and caramely, but this I wanted to be a bit more authentic, and consulting Ron Pattinson's "Homebrewer's Guide to Vintage Beer" noticed that a lot of historic milds had no crystal at all. What they often did have was sugar syrup. Here I am using invert number three, home made, by heating demerara sugar in a pan with a little lemon juice at 115-120 deg c for 150 -210 minutes-ish. I used the oven so I didn't have to constantly monitor the temperature, but this probably means my temperatures were all over the place. Nonetheless a good dark syrup was obtained.

Because It was a dark beer, my water was probably fine, so I didn't fuss about water treatment for this one.

Recipe

The recipe was 20% invert syrup #3 (entered as sugar and adjusted for water weight), 5% chocolate malt and 75% pale (Crisp, flagon). I also added 10g of black malt in 10L just to darken a little more (not part of the percentages).

The hops were 12g of perle at 8.4 % aa at 60-mins for 23IBU-ish.  The beer was no chilled overnight and the yeast was pitched direct. Original gravity was 1.036.

Tasting

The beer (shown below) was bottle conditioned to 1.8 vols Co2. The fist flavour is dark malt, just a little acrid, and perhaps pushing towards (not quite) porter territory. Then there is a slight watery element with a hint of rummy-ness. Quite a complex malt character with roast, sweet at tip of tongue and dry and watery at the back. The low carbonation is nice. The beer is a few shades darker than coke, and is almost opaque but when held to the light it can bee seen to be clear.

The yeast was expressive, but had a slight twang that I associate with the slurry at the bottom of the fermenter. I might need to start oxygenating my wort a bit more  since this is unnecessary with dry yeast, but could be a problem with my no chill process, with limited shaking after transferring hot wort to the fermenter.

A nice but unremarkable beer. I have noticed however,that these slightly boring dark milds definitely get finished the fastest. The low abv, low carbonation and non challenging flavour all contribute to this. It just seems hard to get bored of something boring? Next time I might try and sacrifice some clarity for a little more body by adding oats or something.

Stout with Soured Portion

A dry stout was brewed. It was 70% pale (Crisp-Flagon), 10% homemade invert syrup number 4, 10% roasted barley, 10% unmalted wheat. Water was Bristol water untreated. 21IBU at 60mins using cascade pellets. 5g of cascade at 5mins (10L batch), 10g of styrian goldings at 20mins. (I use no chill so these were actually 5 mins before end of boil for the styrians and 10 mins after for the cascade). I get bored of comercial beers using american hops, (if I want tropical fruit juice, I can buy tropical fruit juice cheaper than beer), but I like a bit of cascade in bitters and dark beers. It can lift them without being dominant.

The invert syrup was treated as sugar when inputing to my software, knowing the weight of sugar that went into the syrup it was easy to work out the sugar-liquid ratio and adjust accordingly. It was 500/820, and it hasn't gone off a few months after, so theres something to aim for if you are wondering how to stave off unwanted microbes using osmotic pressure. I started with waitrose demmerara sugar. The finished syrup was black and had a liquorice/burnt sugar taste, a bit like a cross between a creme-brulee topping and treacle (for those who live in the UK).

I drew off about a pint of unhopped wort to sour, which I kept on top of a radiator for about five days adding a little bit of sourdough dough a few days in. It had developed a sourness and dirty bread aroma by day 5. I then boiled to sanitise and blended back with the main beer once it had cooled.


The beer looked like this,

And was terribly good. When sipping the frothy mousey head, the first flavour is sugar, mix of dark brown and burnt. Then bitterness wells up, both hop bitterness and burnt sugar/roast barley acrid bitterness, this seems to stimulate the whole tounge in a very firm but balanced way and then there is a brief pause of carbonic spritzyness and then just a lingering complex roasty sugary burnt slightly hoppy melange. I'm not sure the sourness is perceptible but might be accentuating the sugary flavours. I was told this is one of the best beers I have brewed.
