Now Brewing: Hip Hop – Nelson Sauvin

OK, not quite “Now Brewing”, but I do have an excuse for not blogging. Here she is with me, Sam and Charlotte at the Bristol Beer Factory stout day.

This is a brew that we did a couple of weeks ago and bottled on Friday. We decided to do a SMASH (single malt and single hop) to try out some Nelson Sauvin, which we’d never brewed with before. We settled on “Hip Hop” as a name to use for this and future SMASH experiments, so this one is qualified with the name of the hop.

The recipe is a simple one with just Maris Otter malt, and three additions of the Nelson Sauvin.

The result is really tasty. It’s a great showcase for the hops, a dangerously drinkable for a 5.9% beer. I’m looking forward to trying some other fancy hops in this way.

Now Brewing: Winter Beermalade

The second brew I made, and the first with extract rather than a kit, was a witbier to which I added a big dollop of homemade marmalade. This was christened “Beermalade”. This weekend we brewed a winter warmer, and decided at the last minute to spice it up with some marmalade. I still have several jars of a very dark marmalade I made a couple of years ago, which also had a little rum in it. In the end we just added a whole jar, so we had to call it Winter Beermalade, to distinguish it from the wheat beer which I’ve renamed Summer Beermalade (and will try to recreate next year).

We’re gradually trying to get our brewing setup just right, and our previous bottleneck was chilling. Frozen Coke bottles may be simple, but aren’t quick. We gaffed around for a few weeks working out the cheapest way to get the bits for making an immersion chiller until we realised it’d only cost about a tenner more to buy a ready-made one, which is bound to be better. So Sam ordered one, and it fantastic. We got from boiling to about 15C in ten minutes, which was an amazing improvement. Overall our brew day took five hours: around 90 mins quicker than our previous one. The next upgrade will be hop filtering. A sheet of muslin really doesn’t cut it.

The brew itself is going really well. A winter warmer is a great traditional British style. A relatively (but not massively) strong ale, with good sweetness and loads of body to warm you up on a cold winter’s night. Unlike some other winter beers, it’s not normally spiced, so our marmalade addition is not traditional, but is delicious. For our grain bill, we used lots of crystal malt for sweetness and body, with Munich and amber malts for more body and a biscuity flavour. We added oat malt and terrified wheat to give it good head retention and hopefully even more rich body. We don’t want the beer to be too hoppy, so it’s a simple combination of Challenger for bittering and East Kent Goldings for aroma.

New immersion chiller

Straining the last of the wort from the hops. Not the best system.

Now brewing: Indian Summer autumnal IPA.

For our second St Agnes brew we decided to do a continuously-hopped IPA with a difference. In honour of the “Indian summer” we were having at the time we thought of it, we decided to give it an autumnal twist. We took it darker than an IPA would usually be, and with richer maltiness from crystal and Munich malts. The hops we chose were English Fuggles, with a total of 20 additions!

Checking the temperature of the mash. I wasn't really that bored: I'd just noticed we were being stalked by a cat.

After the temperature fiascos of the last brew, I bought a new thermometer. It did us well.

First runnings

Bags of dry hops

We added hops every five minutes during the boil, plus at flame-out. We also added 30g to the fermenter. Unlike previous dry-hoppings, we put these into muslin bags, to avoid the bottling stick getting all jammed up with bits of hop. Hopefully the flavours will still come through.

Loads of hops

We used 220g of hops in total!

We hit the target OG on the nail. The yeast was the remains of the stuff I’d got from Bristol Beer Factory a few weeks ago. The brew day was on Saturday, so it’s been in the FV for a few days now. It seemed to get stuck at 1.017 with no change for 24 hours and no bubbles from the airlock. Remembering how it came back to life last time, I roused it a bit this morning and it immediately sprung back into life. When I say immediately, I mean the airlock was bubbling again within seconds of putting the lid back on, and had dropped to 1.015 within a few hours. I’m guessing it’ll be done by tomorrow.

Summer Session in bottles

Two of them, anyway. Most of this is going into the cask, but I’ve filled two bottles to take on a trip. It’s cleared nicely, thanks to kieselsol and gelatine. It’s very refreshing with loads of Citra aroma, as I hoped.


Note the ABV has changed: it fermented more than I’d expected, and I can test it more accurately with my new refractometer.
