British beers - flatness and head

Try adding flaked barley.

There is already 5% wheat in a couple of these, and Carapils in one, so I don't feel the grain mix is to blame.

Finally have you tried pouring into a pitcher then into your glass.... carefully because the effect can be volcanic.

I think this has pointed me to the answer. I didn't feel I was far away, as the PET bottles were nice and firm, sounded right when opened, and the beer wasn't flat but just not as lively as I like. I've been pouring very carefully down the side of the glass, trying to keep sediment in the bottle, but a messy volcano after pouring from a pitcher (yes you did say carefully) delivered a pint with a convincing head. So for now I'm pointing my finger at over-cautious pouring technique. I guess I just need more practice....
