No suggestions here, that looks great to me. I've got to get one of these going for myself... and a schipluyden, the IPA that existed before the English even had a colony in India. Too many beers to brew. :)
You're keen! I'd say specialty grains are a no if you're shooting for authenticity. If you use good quality malts you'll get plenty of flavour and I think they'd end up obscuring the nuances of the oat/wheat/pils. I'd aim for German or Belgian malts but down here the only oat malt I can get is...
I'm keen to brew it but I might not be able to get to it very soon. Definitely post up pics if you give it a go. WY3787 is one of the recommended strains to try but I'd also like to use WY1026 since it's supposed to be originally from the old Oranjeboom Brewery.
Thanks, GaryJohn! I've got Dutch parents so this stuff is really fascinating for me too. I've been in email contact with the guy who runs the site and he's really working hard at getting breweries to start brewing some of these beers.
They've written up some style guidelines for Kuyt/Koyt:
Just resurrecting this thread so there's some info for anyone searching in the future.
The guys from the Witte Klavervier brewery have done a heap of research on historical brewing in the Netherlands. There's heaps of info on Dutch styles and the influence of Dutch brewing on brewing in the UK...
I stumbled across this episode of Basic Brewing Radio the other day. They brewed a beer with 1kg of hops, 900g @ 5 minutes and 100g dry hopped, and tested the IBUs.
