Hopped beer crept into western Europe in the later middle ages early modern era , tucked deep in the hulls of small shops carrying mixed cargo - like what was found in the hold of the Elyn in 1401.

Was Hanseatic League Beer The First in England? – A Good Beer Blog

@agoodbeerblog On a boat abandoned at Graveney, Kent (in south-eastern England) at some time in the tenth century AD a cargo of hundreds of hop flowers was found. This is a probable indication that by this
time hops for use in beer brewing were being traded. Certainly the common use of hops in beer would not come for a few more centuries, but its use was probably fairly widespread already by the end of the first millennium.

@eatingasturias Nice! I do know that the Hanseatic folk were bringing hopped finished beer into England in the 1200s but share that link!
@agoodbeerblog I do love me some beer nerdery, and anything I can pass on while trying to suss out how the term "zythos" got from the Greek name for Egyptian beer to the Asturian name for either beer or cider depending on who you ask, hopefully helps someone along the way
@eatingasturias Here's that Wilson and Conolly 1978 citation in fuller form: "Wilson DG, Conolly AP (1978) Plant remains including the evidence for hops. In: Fenwick V (ed) The Graveney Boat: a tenth century find from Kent. British Archaeological Reports, British Series 53, pp 133–150"

@agoodbeerblog Previously in Nelson 2004 pp 108:
... the rules for the abbey of
Fontanella (a monastery located near the mouth of the Seine River which was founded by St Wandrille around AD 645), made a list of the various tithes supplied to the monastery which includes a reference to ‘as much as is required for necessities’ of sicera <ex> humolone, certainly here ‘beer made with hops’.

So it's reasonable to think that the Graveney Boat may have had hops from the Benedictines of Normandy

@eatingasturias @agoodbeerblog The Graveney Boat is a mystery. But I'm pretty sure the cargo wasn't used for brewing beer to preserve it, simpoly because if that had been going on in the C9th it wouldn't need reintruducing in the C15th
That’s my thought. I’ve looked at a number of later medieval ship’s manifests and see bales of various plants being brought in. It’s like there was a bulk herb trade. @zythophile @eatingasturias
