I can only explain how I brewed this Cerveza and Pumpkin Beer last year ...
Started 12th November 2016
2kg of pumpkin sliced, boiled, blended with 4tsp of All Spice & strained.
Added to Wilco Cerveza Kit with 400g of brewing sugar.
It was a lovely beer but there was only the very hint of All Spice flavour remaining by the time I got around to drinking it.
In view of this, when I repeat the brew this year I will look at adding the All Spice when I bottle the brew, in the same manner that I add Hop Tea.
I'm hoping that this will increase the "Christmassy" flavour when it's time to drink the brew, but how it will affect carbonation and clearing will be in he lap of the Gods! :whistle:
Best of luck. :thumb:
