Early on in this topic/thread/subject, I offered to take a look at complete recipes where you encountered issues. 

The offer is still open.

i explained in the first post, 100% DME fermentables, ~33 IBU or so, ~1.045 OG. multiple brews have this issue. you requested AA%, hop amounts, yeast.

hallertau and EKG hops separately for each brew, im sure you can guess the AA in those, significant amounts, ie total 4-6oz per brew, yeast 1 was S-189 and yeast 2 was WLP550.

please, go ahead and diagnose now that you have the certainly related info of AA and amount of hops for an issue that is 100% the fact i used DME. considering i've never had this complaint before in any LME or all-grain brew.

Have you had this issue with other DME?  Entirely possible it's simply the way that extractis made.

Have you had this issue with other DME?  Entirely possible it's simply the way that extractis made.

I've always used LME in the past.

I don't truthfully know the cause. But I suspect its a mix of causes. I have made brews that are pale that were half LME/half DME with no specialty grains (reason was that the DME was wheat, LME was cheaper and I liked the quality but was not available in wheat.) and tasted very good. I made a belgian single this way that was one of my favourite brews.

The factors I believe are the combination of a lack of flavour of the pilsen/golden light DME i used and a low carbonation. I didn't mention but I targeted only about 1.7 vols for the most recent and about the same for the previous one that had an issue.

maybe exacerbated by some mineral imbalance I am not aware of. https://www.homebrewtalk.com/threads/ion-additions-from-briess-pilsner-dme.186443/


I sampled one last night, and was already pretty drunk but it just wasn't that great and still had the issue, 3 weeks in bottle now.

This isn't a brewing-ending issue for me at all, I do about 50% of my beers all-grain, 25% partial mash and 25% all-extract.


Solution for me, barring someone who has had this issue or can explain it is:

1. stop making pale, all-DME brews.
2. switch back to using LME for brews that are supposed to be fairly pale and accept the slight increase in SRM for an overall better flavour.
3. continue using DME in partial-mash brews or ones with strong specialty grain additions ie. a lb of black malt and a 1lb of crystal on top of a DME base.




the reason for me making this thread was to crowdsource a solution or answer and perhaps warn people of a potential issue (though apparently it isnt one for most)

4. Use different DME

From the water profile,

alkalinity = 73

alkalinity may be a factor:

How much alkalinity is high? [...]  alkalinity greater than 50 ppm can be considered high for extract brewing because you are rehydrating a dehydrated wort that already has minerals and alkalinity in it. The alkalinity in your water will add to what’s already there.

that's a good answer. thank you.

i think i can see potential in this answer. and checking my notes again the first of the two beers i said had an issue in fact was about 2/3rds tap water 1/3 RO water. looking even further back, the extract beer that was very good tasting was made with 100% RO water.

The main way I could figure this out though would be to try a new DME batch.

Try a different DME.

This has probably been the biggest eye opener to me. I tend to stick with one thing and run it into the ground, wondering why I can't get a different result. Realizing that not all "identical" ingredients are actually identical.
