A good recipe that I have used:
1 Can Coopers Dark Ale;
Safale S-04 Yeast (11g Satchet)
50G Dark Brown Sugar
150G Corn Syrup
500g LDME
500g DDME
Tea Bag Tettnanger Hops
Tea Bag Goldings Hops.
Re-hydratred Safale Yeast for 30 Mins.
Boiled (Hgh Simmer really) DDME, LDME, DBS, Corn Syrup, Kit Yeast and Tettnanger Hops for 30 Mins. Turned off heat added Goldings Hops and left sit for 10 Mins. Added Coopers Dark Ale Can, gave a damn good stir, poured into Fermenter, added cold water to 23 Litres.
Added Yeast and left for two weeks to ferment
Starting Gravity - 1044
Left in Secondary for 2 weeks
Final Gravity - 1014
Bulk primed with 30g Corn Syrup and 150g LDME and bottled on 10 September 2006.
Been tasting this drop over the Xmas break and it is damn good, nice head, good flavour.
Brownie.
