I think what you are tasting is acetaldehyde, one of the intermediate products of fermentation. Given more time the yeast break this compound down into ethanol and the taste goes away. At 10 days your yeast just haven't finished the job.

Mixing the extract with water is difficult and often brewers report low OG when it really isn't low at all. Don't worry, if you used the right amount of extract and water, your OG was as planned.

Thanks! I was hoping someone would say something to this effect. This place and the people here a wealth of knowledge! Planning on keeping in the carboy for a total of 2 weeks. Cheers!

Easy clean is not a sanitizer. You need to clean AND sanitize. Get yourself some OXY free or PBW and Star San.

The beer is young and not carbonated or conditioned so tasting is a difficult read but it's
Should still smell and taste like beer.

Interesting, wonder why my HBS wouldn't include a sanitizer in the starter kit??? I'll get some ASAP. Thanks

The air pumps are a good, inexpensive way to get oxygen in the work. Better than my paint mixer for sure.
You do need to run it a lot longer than running O2 since the actual oxygen is low concentrate in air.
Be sure to buy the proper filter though!! You would be pumping a lot of germs into the wort by pumping air through the wort for that long.

I was going to buy an oxygen system (and other brewing stuff ) off craigslist last weekend but the guy was a flake. 13 emails and I still didn't have a phone number or physical address. I came home. Last night I ordered an O2 system though!

I just picked up the airation kit from Northern Brewer. I really got it for stepping up starters, but my main reason for posting is, the little plastic .2 micron air filters are very fragile, and will break if you force the hose on.
Combine this with a hose that is too small for the filter, and bam, you'll have a worthless, broken air filter if you're not careful, but I digress.

From what I've read, 30 seconds of O2 is equal to about 20 minutes of air.

I step up with a constant air bubble, and oxygenate wort with an air stone and O2.

Since this is an Imperial Blond kit, you can be assured that if you added all the malt extract and had the correct amount of water your OG will fall in the range predicted by the kit (1.067 to 1.071) and anything your hydrometer reading shows outside that range is from not mixing the wort well enough. It's hard to get the wort mixed but the yeast will find the sugars and do the mixing for you.

The main reason the wort is dark is from the Maillard reaction in your boil kettle darkening the extract as it boils. For your next brew, only use part of the extract for the full boil to extract the bittering from the hops and add the rest near the end of the boil.

You mention leaving this for 2 weeks in the fermenter but since it is an Imperial Blond the alcohol content will be higher than the standard gravity beers and will take longer to mature. I'd suggest leaving this in the fermenter for 3 to 4 weeks as you will likely end up with a better tasting beer. There will be lots of intermediate compounds that the yeast need time to break down.

IME, no retailer of kits includes actual sanitizer in their kits and for whatever reason it is usually not even suggested which is a huge disservice to new brewers.

Thanks, I'll let it sit for for 3-4 like you said. I'm picking up another fermenter so I can get another brew started... Thanks for the advice!! Cheers

Sanitizer wasn't brought up at all when I picked up my kit. I just assumed it was in the kit. Lesson learned I guess. Cheers!
