I have never had luck getting as low a FG as I want when using extract. This was the main driving force behind me trying all grain. I wish you luck, but i dont know the beadlebrau method is.

I was getting the 10.20 curse A TON. People in various threads contributed it to me using extract and too much unfermentable sugars getting in. I have now switched to all grain and have 2 brews in the fermenters one 6 days old the other 2. In a few days I'll check on the older ones gravity. Ferm temps are no reason for me to not get past 1.020 I am in tempe AZ and work mighty hard to get my fermenters to 70 degrees.

are you rehydrating your yeast? i have found that since i started doing this i have not had this problem (crosses fingers).
Just to note, I just finished using a cooper dry yeast, and the OG was 1.042, it ended at 1.012.
Things I do:
I revive my dry yeast in water, I give my yeast a little LME to munch on, when it is bubbling, I then pitch.
I also aerate my wort by shaking it like this:

I didn't know so many home brewers were suffering the 02 curse.
I just bottled batch of light ale that started at around 06 and seemed pretty much stuck at 02 after 16 days. The beer did taste too sweet at bottling. I bottled this batch in plastic bottles with light priming so as to avoid bombs.
Judging from bottle firmness, this batch is carbing remarkably fast. Don't know if this is good or bad.
The yeast was Muntons Premium. In the future, I will probably stick with my goto yeasts: Safale 05 and 04. And I will darn sure "shake the s--t" out of the fermenter before pitching.
Someone also suggested Go-Ferm nutrient, which is formulated specifically for dry yeast re-hydration as opposed to fortifying the wort. Haven't tried it yet.

You note that your hydrometer reads 1.000 in water, but you don't specify at what temperature. Most hydrometers are configured for water at 60F. If your hydrometer is calibrated to 1.000 in, say, 70F water, then in fact it's off by about .010.
On the other hand, if your wort temperatures were higher or lower than 60F when you took readings, then you'd need to convert. (Higher temperatures mean higher gravity than what you measured, lower temperatures mean lower gravity than what you measured.) You mentioned that one of your beers was a lager, so your wort temperatures SHOULD be dramatically different.

yea my latest brew, a dark cream ale, is stuck at 1.02. is this soemthing i should be worried about? It definitely SHOULD be lower, but if it will still taste good, and not explode then I have no problem.

BTW, what was the OG? If your original wort contained tons of non-fermentables, then 1.02 may not be so bad. But yeah, most beers should finish lower.

I just had a Scottish 80 schilling kit stall at 1.02. I looked it up on the forum and saw a recomendation about adding some calcium carbonate and yeast nutrient. It is possible my water is too soft. Anyway, I did the additions and swirled. Now my airlock activity has been restarted for about 2 days. The yeast was dry Saf-33 and I poured the cooled wort back and forth between buckets 5 times to areate. I've done about 10 batches and about half stall at 1.02

That seems like a high "stuck rate". What kind of yeast and wort process are you using?

I'm doing partial boil's with extract kits. I've had stuck ferms with Muntons, Wyeast liquid 1098 (did a starter on this one, looked just like the pic's I'd seen online) and Saf-33. My problem may be my temp swings. I'm keeping the ambient room temp within the yeast's range but I am having swings of 5 or 6 degrees within the range. I'm trying to find a good used (cheap) fridge or freezer.
Sorry to bring a thread back from '08 but it's the best discussion I've found on the 1.020 curse. So here's the deal, I'm a new brewer and have a couple of batches down and all have stopped at 1.020!
-All were extract (1 LME, 1 DME & both w/grains).
-I've hit my OG's both times.
-Shook the crap out of them to aerate.
-I tried late addition extract with the latest (LME Porter Kit w/grains)
-I used swamp cooler for the first and kept it about 68F using S-04 and fermentation fridge for the second at 62F using S-05.
-Rousing the yeast didn't do anything either...
I like a nice malty beer but sometimes that first drink can be cloying. So the question is, would adding more hops bittering/aroma or both bring the flavor more in balance?

What kind of yeast? I've noticed sticking at 1.020 if I use liquid yeast without a starter in some of my bigger beers.
I've used the dry pack yeast Safale S-04 and US-05 for my beers. The S-04 I know attenuates higher that's why for the second round I swiched to US-05...Maybe I should try Nottingham? I've read it can really drive down the FG. The more I read about DME/LME I think I'll just plan for it to finish high and plan for more hop.
Unless someone has a fix...

Ah weird I haven't had that issue with dry yeast. Are you sure you calibrated your hydrometer and corrected for temperature?
The hydrometer is good and I was just reading another thread and a guy mentioned the boil size. I do 2.5 gallon boils for 5 gallon batch....hmmm....I wonder if I'm causing caramelization by not heating enough water. I'll try doing a 3.5 gallon boil next time and see what I get. Can't believe I didn't think of this before!!! I'm an idiot! Basic cooking 101 the thicker the sauce the more likely of scorching.

Ah I hadn't considered that...My boil is 4g. Hopefully that helps! Although I would expect that to cause an issue with OG not FG.

I've also not had any "stuck" brews, including 2 extract+grain brews (a bitter with OG=1.035, FG=1.007, and a stout with OG=1.059, FG=1.015) and a few partial mashes with OGs in the 1.05x and FGs between 1.009 and 1.014. I have used only DME, no LME, either Briess or Munton's. Always add the extract late (50% late for the all-extract batches).
Yeasts have been Nottingham, S-04, and US-05. There hasn't been much correlation between yeast and FG. The Nottingham gave the lowest (1.007) but also gave a mid-high result (1.012), though the latter was with a much higher OG.
So, I guess this is a bit more anecdotal evidence that is compatible with the caramelization theory. I am very careful to avoid scorching. I remove the pot from the heat when doing DME additions and stir frequently to keep anything from settling on the bottom. I also use a far-too-fancy thick-bottomed kettle that probably helps avoid hotspots, though I do have an electric stove.
Oh, also my 1.007 FG was on a 2.5 gal boil. Most of the others have been 3.5-4 gallon boils. All are 5-5.5 gallon batches.

Zeg...I think you've probably proven my thought.
-I use a cheap aluminum pot
-Electric stove
-I mix the extract off heat but after the hot break and two teenagers always hovering in the kitchen; I'm not real good about mixing...just kind of let the boil do the work.
I think I'm probably carmelizing!

I might not go so far as to say "proven," but it could well be. Certainly it won't hurt your product to reduce the scorching!
