This brew is probably my 10-12 AG batch, but this has been a reoccurring thing.

I'm wondering if this is just a "green beer" problem or something else. Because I have been drinking my beer after 3 weeks or so.

I keg and force carb. I can post a recipe later if needed. I'm at work atm.

Ive hit my numbers and everything seems good except this flavor thing. Even the body and head of the beer is great. It doesn't taste watered down or anything the flavor just doesn't last all the way thru.

Any of you have or had this problem?

Flavor or aroma? All the way through a glass or a keg? How cold are you serving your beer? Are you using frosted mugs? Green beer flavors usually improve with more conditioning time, what types of beers are you brewing?

Its more flavor than aroma. Its after you take a drink and after you swallow. Its almost a flat type of taste left on your tongue.

This is a Pale Ale. And my glasses are kept at room temp. The beer is coming from the tap at around 40*

Its almost like a lack of sweetness.

What you are describing sounds like what is typically described or evaluated as "mouth feel". This generally will pertain to the overall body of a beer and it appears that your beer is turning out thinner than expected and perhaps drier as well.

Since you are brewing AG there are a few things to look at:
1. The overall recipe and and ingredients that create mouth feel and body
2. Mash Temperatures. If you are mashing too low you will get a more fermentable wort, greater attenuation and less body

If you provide some of your typical OG and FG as well as mash temps it is something to look at. Also provide a recipe that stands out as an example. In addition, what temperature are you typically mashing at and are you sure your thermometer is properly calibrated? You may be mashing at a lower temperature than you think.

As for adding anything post I cannot think of anything that would be a beneficial addition post packaging. Things that can be added to the recipes are malto-dextrine or greater percentages of crystal malts or specialty grains that are typically less fermentable than base malts if mashed at the proper temperatures.

A "flatness" can also be oxidation...

+1 to oxidation. Some people taste it as cardboard or paper. Others just taste it as "bland" that mutes all the other flavors.

Are you purging with CO2 prior to transfer? Are you bleeding off the oxygen before force carbing?

Could be oxidaion although I have always tasted that as paper, cardboard like or "sherry" like, never really bland and dull but I guess everyone's tastes can perceive different things.

Not sure what you mean here. If you mean filling the keg with CO2 before racking into it, then NO I'm not.

YES

I only taste this after I swallow, and it kinda just sits on your tongue. Its not even really a taste its more like a leftover unpleasantness. Not really cardboard, just bland flatness. I don't wanna say slimy, cuz thats not really it.

I Mashed this at 158 or at least I thought. I have 3 different thermometers that I'll recheck.

I hit the OG at 1.051, and this went down to 1.013. Fermented at 61*-62* ambient air temp. I ferment in a bucket and don't have a fermometer on it.

Its a good beer otherwise. If I can get a brew down without this, Id be good.

duboman · 10-26-2012, 09:28 PM

If you really mashed at 158 then the beer should definitely have good body and some sweetness as that is a slightly high mash temp meaning a less fermentable wort and it finished at a good number for FG.

You mentioned slimy, possibly and that could be diacytl which some people taste easily and others miss. It could be oxidation as mentioned as you are tasting on the finish. Do your teeth feel slick after drinking, that's diacytl.

Definitely be sure to check and calibrate your thermometers so you know you are mashing at the right temperature.

For oxidation, how are you racking into your keg or any of your transfers?
