It's been a while since I've written about anything German. Or lager. Both of those topics, as you'll have noticed from the title if you're paying attention, will be covered today.
Remember who I keep banging on about how beer styles mutate over the years? That doesn't only apply to Britain. Lager styles have changed, too, though not quite as dramtically.
What do I mean? Take a look at the gravities. The dark lagers in particular had higher gravities than today. But the the crap degree of attenuation left them under 5% ABV, despite having gravities over 1055. Modern dark lagers are quite different. Look below.
Modern dark lagers are below 13° Plato, yet have a tad more alcohol than 100 years ago. The gravity of Export has been whittled away even more. Increasing the degree of has maintained its alcohol level, too. In general, modern lagers are considerably more attenuated than their ancestors.
