From their website:
"Two Birds Golden Ale is brewed using ale, wheat and Vienna malts. It is bittered with New Zealand Southern Cross hops while Motueka and Australian Summer hops are used for aroma. Motueka contributes melon and citrus aromas and flavours, while Summer contributes spice and apricot notes"
Grain bill (20L final volume, single infusion mash @65C for 1h, 85% efficiency, 75% apparent attenuation, 4.5% ABV)
3.1 kg Maris Otter
550g Vienna
200g Wheat malt
Hops:
Southern Cross @ 60 minutes to 15 IBU
1:1 Motueka: Summer (at no more than 1g/L each, i.e. 40 g total hop) into the whirlpool. (if you're allowing 15 minute hop stand before sending it through heat exchange), you can expect an extra 10 ibu's with the assumption your kettle temperature hovers around 95C.
