I take beer research seriously. There are thousands of independent breweries, so even the most determined researcher cannot explore every possibility, but I do my best. I find research more comfortable when watching a Serie A or Bundesliga game or a BBC4 documentary.
Other than that, birdwatching, walking (not as much now due to duff right foot), travelling (32 European countries thus far - just 19 to go) and reading (19th-century literature a speciality). I write as well - my first book was published this year and my first novel is out in January.
That lot is more than enough to keep me occupied. The money's rubbish, but the hours are good (not so different from being a student).
