ok now for full recipe
ingredients:
1250g roasted chestnuts (used about 2.5kg before roasting and peeling to get)
1900g Munich malt
300g Mroost black malt
1000g malt extract
500g chestnut honey
40g Styrian Golding dried hops
1 baggy (10g) of dried ale yeast (Mangrove Jack's M36 "Liberty Bell")
Steps:
- roasted chestnuts in oven, 45min 200°C
- chestnuts were coarsely ground and added to malt (also coarsely ground) for mashing, 1h at temperature ramp 55-65°C (nothing fancy I just put it on the stove and kept track of temperature so that it was slowly rising, mixing every 5mins or so)
- resulting mash was then extracted 3x at ~65-70°C so that I obtained 3 pots of wort of decreasing sugar content
- 1st and 2nd wort were just boiled and put into cooling
- 3rd wort was added malt extract (extra fermentable sugar) and chestnut honey (also extra sugar but also bitterness) and brought to boil
- when boiling heat was turned off and hops were added, for 15mins (if I were bittering with hops, I'd need to add some hops at the start already, but chestnut honey takes care of this in this case)
- when cooled down to lukewarm temperature, wort was put into fermentor (about 16L altogether) and water added up to 23L mark (I have about 28L fermentor when filled to brim)
- initial temperature was 24°C, initial density 1043g/L (which means about 11.5° Stammwürze – with malt only I'd expect to get to about 4.8-5% final alcohol with this)
- yeast added & sealed under airlock for fermentation (room temperature for ale), expecting to bottle next Sunday
