Let's Brew Wednesday - 1911 Heineken Bok

Unlike some of my Lager recipes, this one comes from a brewing record. Though not a full brewing record.

Because, while it does have details of the ingredients and the fermentation, there’s nothing about mashing or boiling. Which is a bit of a bummer. So those bits are just guesses.

Apart from the shit attenuation, this isn’t a million miles away from a modern Dutch Bok. Reddish in colour, malty and without a huge amount of bitterness. It is a lovely beer. I know because I’ve drunk it. Coronado in San Diego brewed the recipe a couple of years ago. Dangerously drinkable would be my description.

There’s still a Heineken Bok, though 20 years or so ago they changed it to a Tarwe (wheat) Bok. I’ve heard rumours that the current Amstel Bok recipe is closer to the original Heineken one. I can believe that. Or rather, would like to. Amstel Bok is my favourite Heineken beer by a long way. And stupidly cheap. I get stuck into it every Autumn.

This was a beer brewed in Heineken’s Rotterdam brewery, located on the not very might river Rotter. It wasn’t far from where I used to live in Rotterdam. I used to walk past the one remaining bit – offices I think – on my way back from town.

Did the version brewed by Coronado end at 1.029? I'd have a difficult time stopping there, even with a super high mash temp on the second decoction. The only way would be to crash when desired gravity was reached...

Pretty amazing that a lager with a simple grain bill like that, would only get 56% attenuation. Did they rack and filter it too soon?

I think I will brew it with the WY2308 Munich and WY2206 Bavarian yeast cakes that I will have available once my latest pilsner finishes.

Brando V,

pretty sure the Coronado version finished lower, but I haven't seen the stats so I can't be certain.

A Brew Rat,

the attenuation of the finished beer was almost certainly higher as the FG is at the end of primary, before any lagering.
