Researchers at Aberystwyth University are attempting to solve the problem of bad tasting beer.

Yeast often suffers heat damage during brewing which can cause a bad taste.

The researchers are trying to understand why some yeast cells survive high temperatures and others do not.

Dr Hazel Davey said: "Our lab strain of yeast recovers well if provided with nutrients during the hot conditions, whereas the brewers' yeast shows better recovery in the absence of nutrients."
