my beer smell like yeast. taste is ok but there is a strong off odor.
How long have you been brewing? If you are new to the wonderful hobby, the smell may seem strong but is pretty normal depending on the stage of fermentation. When I transfer my beer to the secondary, it smells very strongly of yeast but this calms down after a while.
If you have brewing for a while, then something else might be going on and I am unable to help you without more information, but if the beer tastes fine then I would say that it is nothing to worry about.
