Hi, i have brewed 3 batches for beer now all different flavors, but i continue to create a very skunky hops flavored beer. The 2nd batch i realized after the fact that i put the lid on the wort after the brew and may have caused it to drip the condensation back into the wort creating the sulfur flavored brew. The other two batches i followed the directions in John Palmer's How to Brew guide, but also created a ver skunky finished product. I am not sure what i am doing wrong, any suggestions why i might be brewing up batches of skunky hops flavored beer?
Thanks

Are you exposing the beer to sunlight anytime from fermentation to drinking? I know basic question, but the first thing I think of when a beer is skunked is hops exposure to sunlight.

Yep, if it's a definitive skunk flavor/smell, that's usually a sign of exposure to direct sunlight, UV light, etc. This can happen any time from the fermentation stage in a glass carboy to using bottles that let in too much light.

Skunky beer comes from its exposure to light, or specifically a reaction between the hops and light. What kind of bottles are you using? Are you fermenting in a carboy? If so, are you keeping it in the dark?

I normally have a 5 gal plastic bucket for the first stage, a glass carboy for my 2nd stage and then bottle in brown bottles. after each step i store the beer away in a closet, but havent ever put a trash bag over it. also all the beers were lighter beers such as pale ales and some lagers. i dont think they have been exposed to too much sunlight, also what part of the brewing process should i be cafeful about not exposing the wort to sunlight.

I would say be careful through the whole process. From putting it in your primary all the way to bottling. Im not an expert as I am only on my 5th batch (and one batch of wine) since January, but I ferment mine in a bucket and have never had any problems.

How long ago did you brew it - could it just be green beer?

What is the temperature of the wort as it is fermenting? Are you fermenting too warm?

Sounds like you may be fermenting too warm. Do you have a setup for lagers? Lagers need to ferment below 55 degrees generally. How are you controlling the temps?
