Slight medicine taste in my kegged beers that fades with time. Cause of this?

[msa8967]

When ever I brew a light blonde ale, cream ale or lawn mower beer it will have a slight medicine taste for the first week or two it is kegged and stored in my keezer. After 3 weeks the taste is gone but I cannot figure out why this just happens with my lighter beers and not my apa, ipa and darker beers. I do carbonate in the keg using either cane or corn sugar at about 1/2 the amount I would use in bottling. Anyone have ideas on why this is happening?

My guess would be it's there for the darker beer or ipa'a but the taste is being masked. As for the taste I'm jig sure about. What cleaners do you use?

I agree with Rockn the heavier maltier beers are masking the taste. I'd bet it's the Carbing sugars. After 3 weeks all of would definitely be gone. Maybe try carbing with CO2 as an experiment?

I use pbw to clean my brewing gear and kegs but I use beer line cleaner for my liquid lines. I switched to carbonating with natural sugar 2.5 oz for 5 gallons and stored 3-4 weeks at room temp (68 F). My idea was to be ready to switch out an empty keg with a full one and only need a few days to cold condition to get the beer ready instead of 2-3 weeks to force carb the beer. Like I mentioned after being cold and on the gas for 3 weeks the lighter style beers taste just fine and the slight medicine taste is gone.

Could be phenols that are still being cleaned up or from the addition of the late sugars? How long are you leaving in primary before kegging?

I usually leave the beer for 3 weeks in the primary.

2-3 weeks?!?!? Force carbing should take 10-14 days tops.

I never even though of that. That's probably the answer right there.

Maybe you're not rinsing your beer line cleaner well enough?

Agreed.
