House lager update & House Mild

First off, a quick update on my house lager. This weekend, as it had been fermenting for a week, I though I would check how close to final gravity it was, as I was wondering if it was time to ramp up the temp for a diacetyl rest. All I can say is that this yeast (M76 Bavarian Lager Yeast) must be a slow burner, as it had only dropped to around 1030. At this rate, it will need 3 weeks or so to hit FG. Blimey! It was very active, so I don't think it had stalled. I'll check it again at the end of the week.

Next up, I'm going to have a shot at developing a house dark(ish) mild. My recipie at present is as below, which I ope to get on Weds or Thursday this week.

House Lager update

Having been away working all weekend, I wasn't able to check on the lager. When I returned on Sunday, nothing seemed to be happening, so as this was 48 hours later (almost) I bottled it and increased the temp in the fermenting fridge to 12°. Today (Tuesday) it's fermenting away happily. I don't know if the MJ yeast has a long lag time, perhaps I should have been more patient. I'll test the gravity at the weekend to see how far is got and if it's ready for its diactyl rest. Then crash cool, bottle, carb up and lager.

Up next will either be a Belgian golden , double or and English light mild.

First brew in ages - House Lager - version 1

It been a while since I blogged. Due to work commitments, brewing time has been non existent. That changed today with a quick cheeky lager. Here is the recipe;

MASH GUIDELINES:

2) Sparge, Temp: 75 C, Time: 15 min, Amount: 16.1 L
Starting Mash Thickness: 4 L/kg

YEAST:
Mangrove Jack - Bohemian Lager Yeast M84 x2 (Edit - that was a mistake, it was M76 Bavarian Lager Yeast)

Fermentation Temp: 10 - 15 C

The thin mash was an experiment. I brought my mash tun from a chap on eBay - and he had said it benefited from a slightly thin mash, so I thought I'd give it a go. Certainly,  the actual pre-boil gravity of 1.038 against 1034 predicted suggests it doesn't harm efficiency.

I used of Magnum instead of a more traditional German hops because I got some cheap hops (and yeasts, and a few other bits and bobs) from a home brew shop that was closing down. Magnum was one of them, so I wanted to give them a spin in something, and I have read about lagers that use them so it seemed like a good idea. They certainly smell fantastic. They are mainly a bittering hop, but I really liked their aroma.

The MJ M76 Bavarian Lager Yeast was one of the yeasts I got cheap - 50p a pack! I decided to use 2 and ferment at the bottom end of the recommended range. That is 9-14°, so I chose  10° as it gives me a bit of wiggle room.

Everything went really well. The brew day was worked around a day working from home, so things like mash times might have been a few mins over if I was in the middle of something. Which I was, a lot, but they were there or there about. One thing I did for the first time was to whirlpool the wort after cooling to try and gather the trub in the middle of the boiler and preventing its transfer to the FV. I am astounded how well this worked ~ the wort entering the FV was almost totally clear / bright. Now, if you don't do this, this trub falls to the bottom of the FV anyway, so you could argue whats the point? Well, I want to get into liquid yeasts / re-culturing yeasts from the FV trub, so the less muck in there the better.

The immersion chiller got the wort down to low 20's°, it was then put in the fermentation fridge, which  was bringing it down about  2° an hour, so the yeast was pitched at 15.5° which means it will be around 10° by the time it has re-hydrated and got going.

I am now away for work for 3 days, so I'll just have to hope it starts and ferments away happily at this temp, as I won't be there to change anything!

Brews update

The Barklay Perkins Sparkling Beer is carbed up and ready. It tastes really promising already, which might suggest that the CML California Common yeast needs less lagering / cold conditioning than their Kölsch yeast. It's an interesting beer.

The Barkley Perkins IPA is also ready, and looks and tastes absolutely amazing (see pic). I'm only drinking at the weekends, so I'm just having a few every week, and it will be interesting to see how this improves. The over attenuating MJ New World Strong yeast hasn't appeared to ruin this at all; but it would be very interesting to brew this with a yeast that doesn't attenuate as much to see how it differs.

I now have nothing brewing or conditioning (well, apart from 2 more WOW's ~ Apple, Grape & Raspberry and Apple, Grape and Cranberry), so I'm planning my next 2 brews. Both will be some kind of lager, as I got a job lot of Mangrove Jack lager yeast from a store that was closing down, and want to take advantage of the last of the cold conditioning weather!

1934 Barkley Perkins Draught Lager update

This is how it looks after just over 14 weeks. It tastes great, you can taste the Saaz, but it's as clear as a bell and very, very moreish.

I also bottled my WOW's, and the next day knocked up two more, one double grape and apple, one grape, apple and cranberry.

Hewitt's Brothers, Grimsby

I am always interested in the brewing history of the region in which I live. The largest brewery around here must have been Hewitt Brothers in Grimsby, who at their peak supplied over 300 pubs. I'd love to get my hands on some of their brewing records and have a go at recreating one of their beers. I wonder if they used the Yorkshire square method? Wyatt was their yeast like? In the meantime, here is a photo of the brewery in it's prime.

1928 Barclay Perkins IPA

There is something about this recipe that jumped out at me from Shut up about Barklay Perkins. It sort of shouted 'this is what IPA'a used to be' before they became overly strong flower bombs. I can't find American 6-row malt anywhere in the UK, but read somewhere on a substitution chart to try UK lager malt. I had hook head pale and lager in stock so they were used. Finally, I don't have actual #3 brewers invert to hand, so made a substitute using the unrefined cane sugar and the dilution method here. One of the yeasts Kristen English suggests is Notty, so I used Mangrove Jacks New World Strong, which is really their Northern English Brown, and is meant to have similar characteristics to Notty.

So the final recipe was;

HOME BREW RECIPE:
Title: 1928 Barclay Perkins IPA

Style Name: English IPA
Boil Time: 120 min

2) Sparge, Temp: 72 C, Time: 15 min, Amount: 23.5 L
Starting Mash Thickness: 3 L/kg

YEAST:
Mangrove Jack - New World Strong Ale M42

My weighing scales packed up, I suspect a flat battery, just as I was going to weigh the last hop additions, both fuggles. Luckily, I had an unopened 100g bag of them. So I split it in half visially to get 50g, the visually split this into thirds as the two additions add up to 50g in a one third / two third ratio, give or take.

I dod the whole mash / boil outside to minimise the smell in the house (I usually mach in the conservatory), so I'm not sure how that affected the temperature retention in my mash tun, I really must get a digital thermometer with a probe so I can record this sort of stuff. Finally, I treated the water using Grahams Wheelers calculator to give a 'Dry Pale Ale' profile.

All went well, all be it a very long day with the long boil and mash times. I hit exactly 1050, and my pre-boil gravity was within a point as well. There was tons of cold break / trub / gunk in the boiler, however, which I didn't want to carry through into the FV, so I only realised 18.5 / 19L into the FV rather than 20, but I'm not that fussed. The immersion chiller got the wort down to 16.5° before I knew it, so the yeast was pitched at that temp and the fermenting fridge set to 18°. 18 hours later, there was some signs of life, but by 24 hours it was in full swing. Really looking forward to this one!
