I usually run with half dextrose half malt in my kits. Main reason being I don't like high hopped beers (prefer coopers ales, wheat beers, stouts, porters etc), so I can't counter malt sweetness with added hop bitterness. Other reasons are of course the kit manufacturers don't prehop their kits for someone chucking in 1kg LDME. They are based on k+k, or "brew enhancers" at most.
Even adding some amount of hops and doing a boil hasn't helped much. It just comes out too sweet! So in goes the dextrose to replace malt :(

Anyway, is it just me? I've been researching more and more and come across some brewing info which stated extracts have a higher amount of non-fermentable sugars in the wort than AG worts.
If so that explains a lot to me. They also said if steeping some grain to add, the enzymes from that can help breakdown these non fermentable sugars to help fix the problem. Anyone tried this, heard/read this?
I'm still deciding on going all extract and dealing with this problem, The other option is sticking with prebittered kits like using coopers draught for LME and treating it like it's unhopped LME in my calculations for a full plain extract brew using only DME/LME. E: skipping the 60min bittering hopped boil because that makes no sense with extracts, but doing a 15-10min and/or 1min/flameout hop additions for flavour and aroma

E: Or if doing a half batch, - by that I mean full kit but only half the water so it's like a 23L toucan in flavour/bitterness etc - I can add ldme for sweetness and bring ABV up, and play around with the amount of DME for sweetness to balance a kit hopped/bittered for 23L, or use yeasts with lower attenuation to leave more of this non fermentable sugars in extracts/kits if it's true.
 
Why don't you have a go at using only non-hopped extract, then you can properly manage the bitterness yourself.

I've never seen a reason to use pre-hopped extract - maybe I'm a bit of a control-freak. I feel like some of my flexibility and choice has been taken away before the start. It's really easy to boil a bunch of hops in your wort, and allows full control over the bitterness. You don't have to boil the hops in all the wort if that's a problem - boil them separately, or look-up how to do it in a coffee plunger. Or do boil everything, but in a 1/2 or 1/4 batch size.

Malt extracts are engineered to have a specific fermentation profile, and some are more fermentable than others. But the problem you're describing (assuming a full fermentation) is the balance of the bitterness. You could try adding some pre-isomerised hop oil (e.g.: http://www.morebeer.com/products/isohop-bitterness-extract-1-oz.html ) to the finished batch to balance it out. Some hop oils require boiling, so be careful what you buy if going down that route.

You say: "I don't like high hopped beers" - but a beer can have a strong hop presence without being bitter. It just depends on how long the hops are boiled for. As an extreme example, if you put all your hops in the last 5 minutes of the boil, it would come out very "hoppy" (aroma wise), but since the alpha acids in the hops did not have time to isomerise (which allows them to dissolve into the wort), the bitterness would be low.

I have. That's the point, all malt extract brews always end up too sweet for me regardless of hopping if I want to keep them down to a level I like. EG it's like cooking. I could add 1 Tbsp vinegar, or fish sauce or whatever, "balance" that with 1 tsp sugar, but there's no coming back from 1/4 cup of vinegar. You could attempt to "balance" it with sugar, but it's all off and too much of both.
I don't have a sweet tooth at all, so I just hate it and don't like introducing bitterness to fix it and having it strong overall in flavours to "balance" it.
E: OK, I'm going on about sweetness and malt extract, but comparing it to vinegar in cooking that needs sugar to balance - ie the opposite, but I hope people get my meaning.

I recently did two coopers kits (lager brewed as an ale). One had 500g LMDE, 500g dex, it finished at 1010 and tastes sweet to me. The other had 400g LDME, 500g dex, finished at 1008. It's drier tasting, less sweet and a better beer.
Of course it isn't "real beer", but that's the point I'm making in the kit/extract subforum. Is kit/extract malt sweeter than beer should be in the first place because of the process extracts go through - ie do they contain more un-fermentable sugars than AG beer does?
I once made a beer years ago all extract and it was so sweet it was undrinkable.
I have a serious unsweet tooth, a couple of years ago I tried to quit smoking by using e-cigs (I was a bit more involved that that because I ended up with rebuildable atomizers/drippers etc), but I didn't like many "e-juices" because I found them too sweet as well.
 
The amount of unfermentables in AG beer differs depending on the mash itself. There's no "kit beers contain more unfermentables than AG beers" standard. Besides that, unfermentables don't necessarily contribute to sweetness, they contribute to body and mouthfeel.

This all sounds a bit weird... you don't like the sweetness, adding bitterness to balance is about the only way to fix the problem yet you don't want to do this? It doesn't seem like you have much choice to me. It also doesn't mean you have to go way over the top with bitterness, but just add enough extra to counter the sweetness. The lager kit you reference is not high in bitterness anyway, so that would explain that one turning out a bit sweet.

Although do have a bit of a sweet tooth, I don't like overly sweet beers either, so I simply brew them with an amount of bitterness that nicely counters it to my taste and the beers end up well balanced in the end. Not too sweet, not too bitter.
 
He's talking about malt extract versus mashed grain and is correct about higher finishing gravity and sweetness in extract brews.
From memory, it is related to free amino nitrogen levels.

@pablo - There is absolutely nothing wrong with using a portion of dex in a malt extract brew if you find all ME finishes too sweet and thick.
Control the balance to get the beer you want.
Are you unhappy with how your ME + dex beers are turning out?

Also make sure you pitch enough healthy yeast and use a decent yeast nutrient.

Definitely try adding a healthy dose of yeast nutrient.

Which yeast are you using? It may help to use a more highly attenuating one.
 
+1 to manticle. I think the extra sweetness also has to do with caramelisation of the sugars when reducing to a syrup. Have you had the same issue with fresh wort kits?
 
The mash for malt extract is also mashed at a higher temperature than we normally do for an AG mash.
They can be mashed at 70ºC or even higher.
The reason is to ensure the final beer has some body and maltiness to counter the traditional kilo of sugar used along with the can.

Once you add things in place of the kilo of sugar, then yes, you guessed it, your unfermentables go up, and you end up with a sweeter beer.

If the OP was to use all dextrose as his/her addition rather than 50/50 dextrose/malt the final beer will be less sweet. His/her post already contains the answer. Use all dextrose as the addition. Or he/she can take a punt and add an enzyme to ferment it our further, but I personally wouldn't go down that path.
 
Pablo, I know the sweetness you are talking about and I also do not like it.

Really as mentioned there is only two things you can do.
Either balance out with bitterness which doesn't work well if you want a low bittered easy drinker.

Or sub some malt for dextrose.

I do a lot of extract brews to about 30 ibu and find them too sweet with all malt. My standard base is 1.5kg liquid malt, 700g dry malt and about 600g dex in 21 litres which finishes at about 1010 ish.

If I make a less bitter beer I sometimes drop the dry malt to 500g and up the dex to 1kg.
I generally use US05 which is a fairly good attenuating yeast.

Also depends on which liquid malt you use. I use coopers but I think briess is more fermentable.
 
Try a different yeast an keep the temperature in its comfort range. I am a big fan of Danstar Belle Sasion. It eats more sugars than most.

Not unhappy, but want to move from the traditional old coopers range. I could buy their upper/new range, but they're a bit of a rip off at over $20 for the premium ones compared to buying LME or DME and following a recipe IMHO, and following a recipe gives me more control as I don't know what is exactly in the kits anyway.*
But here's the problem with all extract recipes for me, sweetness.
Like I said before, beside using half dex, maybe I should use the cheap lager or draught kit and treat that as pale malt base LME, add some more bittering hops like it was non hopped, which would allow me to use all malt for the rest of the recipe.

I dunno, I just started this topic to see if I was crazy or whether extract brews are in fact sweeter. If that's the case then maybe when I come across ag recipes or extract recipes that were converted from AG, I know before starting that they're going to be sweet tasting, and therefore make adjustments before I start (like extra bittering hops or use a pre-bittered coopers lager/draught kit for the base LME.)

*e: second point is steeping some grain or buying enzymes may help break down the sweet malt extract unfermentables?
 
You can do unhopped extract, keep the IBU where you want and use some dex as well to balance. No need to use cheap shit - use some quality briess extract that has been made for brewers.
 
I've been looking into this problem further. Seems using a far bit of dextrse can cause this problem because yeast don't power through the malt so easily. I think that is a related problem for one batch I did with 500g ldne and 500g dex when I made a starter using dex (which is a big no no). Plus also having lots of stuck at 1020 brews in the past when using all dex.

Been looking into enzymes, "pilsner enzyme" "low carb enzyme" etc and found this interesting read http://www.brewery.org/brewery/library/enzymes595.html
 
But aren't you mostly experiencing this when using all malt as opposed to some dex?

I think stuck brews with lots of residual sugar is more of an issue than kits or LDM or Dex. I used European Lager can with 1.5kg of LDM had it finish below 1.009 (I'll have to check my notes) and the last think you would call it was sweet.
 
manticle said:

It was the worst when trying all malt in the past.
The dex thing was just an interesting point made in that link that could explain some stuck brews in the past.
It's just a side note.
For the brews not stuck and ferment normally, brews made with all malt extract do still taste too sweet to me even when finishing at 1010 SG..

Ok, so I broke out the spreadsheet, and it doesn't lie.

If you use 1 can and 500g LDME and 500g Dex on 23 L at 75% attenuation you should get 1.008. I have got 75% with Windsor when I have used it. When I used US05, Nottingham or BRY 97 I get around 81% attenuation using kits. This takes it to 1.006. So at 1.010 (unless BE or maltodextrin is used) it is not fully attenuated and will have some residual sweetness. At 75% and 1.008 it will probably have some residual sweetness or maltiness that might get perceived as sweetness.

If you use 1kg of dex you should get around 1.004 with US05 etc

If you use 400g of Malt and 500g of dex you should get around 1.006, so 1.008 isn't too far out of the range.

I suspect that you are not attenuating fully. Look at your yeast. Either your yeast choice, it's age from the LHBS, how you pitch your yeast or temperature or more likely a combination.


As I said, I have used 1.5kg of Malt with a can, on another occasion a can plus 1.7kg of unhooped malt (black rock) and not got the residual sweetness you describe. Of course your taste bud and mine will perceive flavour differently, but the FG's you have been getting line up with your observations of the sweetness.
