One of the oddest things about the whole Albany Ale thing is realizing it does not much matter if you get the recipe right. You need to know what they made the stuff on, what their expectations for the result was and maybe even how the beer fit into their lives. All across a history that is in its fifth century. Back to the 1600s. Hmm.
Don't get me wrong. There are hints. To the right is a detail from the Rutger Jacobsen window from the Reformed Protestant Dutch church in Albany erected in 1656. Click on it to get the full image. Rutger Jacobsen Van Schoenderwoert ordered the window for the church back then and it has survived the 357 years to this day where it can be found in the collection at The Albany Institute of History & Art. I presume that Rutger is the Rutger Jacobsz who brewed with Goosen Gerritsz about that time, as Craig described in his post and was mentioned in this comment from three years ago. Which is swell. But what I really presume is that the image of the brewing implements in the stained glass represents a 1656 vision of brewing implements. Tubs and paddles.
The handiest information about the tools of mid 1600's brewing can be found in the 1651 inventory of the personal estate of Jan Jansen Damen. There are kettles, barrels, sacks of all sorts of malt, a grain sieve and sacks of hops from Holland. Trouble is there are also a dung fork and a dung hook. And a Bible. And 2 copper griddles for pancakes and a whole pile of other stuff. There is likely a listing of anything that might ever be found in a mid-17th century farming operation in the Hudson valley. What was used as part of the brewing process and how was it used? Dunno.
How to figure it out? There are hints in art. Just look at that bung hole! That might mean something. But can it all add up to to an understanding of the techniques that, in the proper sequence, added up to the thing that game them familiar, comforting drink they knew as beer? Dunno.
