Heady Topper? 8% alcohol. Seems a good fit for the UK market. I tried most IPAs available in London and France and they seems to me to go in two directions: 2x percentage of alcohol or using various syrups. They invariable give me headaches and I keep coming back to traditional beer.

Just FYI - in London, IPA is a very traditional beer. Just not the hop-bomb american styles.

Go for cask real-ales on the big pumps rather than craft beers off the keg taps, and you're drinking old-school British beers brewed in the way they have been brewed for hundreds of years. Some of them will be IPAs. Most of them will be in the range of 3-6% alcohol.

They don't tend to be as massively hopped and flavoured as the newer 'craft' styles, they are less fizzy (natural carbonation only, rather than forced keg carbonation) and might be kinder to your head as a result.

There are session IPAs and pale ales, which are both lower in ABV probably 5ish or less ABV-wise, re. headaches and just as flavourful hop-wise.
