Extract Brew

Postby Rolfster » Mon Feb 12, 2018 21:18

Hi all

I've been very busy with work and life in general, so have not got the time or energy to do a full brew day.
We have a bit of shindig planned for Easter, so SWMBO has been bugging me to get a brew on :party: :oops: :party:

So I've decided to have a play with extract. I've order 7kgs of this from Rob https://www.themaltmiller.co.uk/product ... ight-25kg/

and I'm planning on doing my normal split brew.
half APA and half earl grey IPA.

A few questions to anyone in the know....

Full 60 minute boil? Or shorter? Longer?
Will there be lots of trub?
Any idea on the FG?
I have some speciality grains. If I steep them will they add anything to the party?

Any other thoughts would be great!

Cheers Tim

60 minutes for the hops, I used to cram as much base and crystal malt into a cheesecloth, our local sari shop sells it , as possible tie it up with string and do brew in a bag thing for half an hour and drain sparge in a colander. Can't remember about trub. ..can't be more than I get from Minch malt right now. The grains were .5k crystal and about the same of Maris or a bit more if your colander is big enough it made a mahoosive difference to yeast vitality and taste.
Wow..dream wife or what .... asking you to make beer. Is that in the kitchen ?

Yes it's in the kitchen. The only limiting factor is that I do it when no one else is in! So I've got to avoid school holidays and stuff.

Think of Extract brewing as AG brewing without the mash - same process, 60min boil with the usual hop additions etc. The jury seems to be out on whether to boil with the malt in or out, generally I add a bit of malt to the boil but not all of it. Can be especially trickly with liquid malt as it drops to the bottom of the boil pan and can burn if you don't stir it in quick enough.

You won't get nearly as much trub as you get with AG.

Definately worth steeping some speciality grains.I've got to the point where I now do a mini mash with my Extract brews with some base malt as well as speciality grains
i.e. half AG and half DME.

I did a partial extract brew last weekend - just a mini mash for the speciality grains, then a 60 minute boil as usual.

2016: 330L brewed (72 gallons, over 8 firkins)
2017: 105L brewed (need to update this figure)
Drinking: Landlord clone
Conditioning: ciders from 2016, hedgerow barrolo, 1914 Courage RIS (10%).

Cool. Thanks for the feedback. I've put in 250g of cara gold and Maris otter and 200g of Maris otter (steeped in a pan then brought up to 80 degrees before straining and adding to the boil.

It's boiling away now. I just need to figure out how much water to add now to get it to the right strength. It seems a bit stronger than I thought!

I'm flying by the seat of my pants...... and enjoying it!

I just got it all done!
Ended up with 8 gallons of 1.056 wort.
Bittered with galena to 34 ibus (30g)
Then at flame put 17g of amarillo and styrian goldings and 20g of mandaria baveria.

Split between 2 fvs and one had cold steeped earl grey tea added. All are fermenting with us05 and clarity ferm at about 18 degrees.

Slight derail - how does an extract brew compare to kits and all grain brewing?

I love doing AG brews, but time is a problem (I have a 4 year old kid, they eat money and time). I can find time to do kits, but they're never as good - drinkable, but nothing special.

I wonder if an extract brew would be a good compromise?

So I started the brew at 11:30.... like that was when I dragged my boiler out if the cellar. I picked up my youngest from nursery at 3 pm and had just about finished and cleaned up. And that was a double quantity. Quality wise it's still fermenting so I don't know!
If it's good I'll definitely do it again.

I think extract brewing is better than kits - you have fresh hops, and (hopefully) better yeast more suited to the job rather than a jack of all trades.

I tend to still boil for 60 minutes, but that’s because I’m too mean to add more hops to get the IBUs in a shorter period. A 15 minute boil is entirely possible - I intend to try this on my next brew with a load of Amarillo.

Right, I'll give that a go then! I'll try a few 1 gallon batches first to figure it out.

Thanks!

Lately I've been doing brews with 50% grain and topped up with 50% extract (DME), I do it all on the stove-top BIAB and the smaller volume of grain means less water to both heat up and cool down, thus reducing the brew time. I top these up to volume with cold water after the boil.

I really can't tell the difference between between these beers and AG, but I can now get the brews done in a much quicker time (at least an hour shorter). I use brewing software to alter AG recipes for a reduced base malt and added DME, to keep the same FG.

So this is down to 1.010 and tasting really quite nice straight out of the fv!

It's still got a good karusen on both fvs. I've just added the loose leaf tea and dry hops. I will leave it at about 21 for another couple of days and then put it on the cellar floor to chill before bottling in a week or so.

I got this bottled last night. Its about 6% which was a but stronger than I thought it was going to be!

The earl grey smelt like juicy fruit chewing gum! And the apa smelt ok.... given that I added 80g of hop pellets I'm a little disappointed it wasn't more hoppy. Will report back on the results in a few weeks.

Tried one of each of these tonight.
The jury is still out on where or not I'll do an extract brew again!

The earl grey ipa doesn't taste right.... but I think I aways say that when tasting the first bottle!

The apa taste quite nice, but a bit sweet.
I'm going to give it bit more time in the conditioning cupboard before it goes into the cellar. Fingers crossed because it saved quote a bit if time!

Just tweak it a bit next time. You can make some great extrract brews and it really does save a lot of time.
