I'm planning an extract doubble in a while and just got my ingredients... going with:
recipe designed for 6G batch (expect .5G loss to kettle/trub, and .5 loss to primary fermenter... leaves 5G for bottling.
8 lbs olden light DME
1 lb munich LME
2 lbs D2 candi syrup
1 oz Kent Goldings at 60 mins, and 1 oz Styrian goldings at 15 mins
I might sub 1 lb of the D2 with 1lb of table sugar though for a little more lightness.. of course the slightly more ntense flavor and darkenss would be good too... originally I was going to go with 2 lbs of D1 but the HBS was out so I took D2. Should be yummy.
