C'mon Boagsy. Either come back with an extract recipe for a chimay clone or your reply is a waste of bandwidth.
Easy enough to research one. Use the Style Guidelines, google, Jamil and Palmer's Brewing Classic Styles or whatever resources you have at hand and some brewing software.
I don't know which Chimay he's trying to clone and I don't know off hand what they use hop wise, IBU's or EBC's so I will just go for a Belgian Tripel.
I've never made a Belgian but with a little research here's what I would start with,
1 can Coopers Wheat LME
1kg cane sugar
2kg LDME
500g clear Belgian Candy Syrup
100g Dingemans Aromatic Malt steeped in 9-10 litres of a water @ 67 degrees C for 30mins (if you're worried about starch conversion use Carabelge)
50g Hallertau Mittlefrueh @ 60 mins
20g Saaz @ 10mins
Wyeast 3787 or safbrew T-58 using a nice big 3-5 litre starter.
Add the candy syrup toward the end of the boil.
Start fermentation at around 18 degrees C ramping it up until you hit about 26 degrees C after a week or so.
Add the cane sugar around day 3 or 4.
Try it at your own risk, it's never been brewed before and is just a quick stab in the dark.
You might want to ferment this out over 3 or 4 weeks in the primary and be prepared to age it for a few months in the bottle.
