Having been given a recipe for a 10l extract brew (and bought a le creuse  6.7l casserole), I'm wondering if I can use my 6.7l casserole to make either a 5l or 10l batch... I've bought the grain, extract and hops to make the brew...

Cheers in advance

You could do the whole 10 litre batch, a full volume boil is not essential. Boil as much as you safely can, top up with cold water in the FV. Cooled boiled water is best.

So follow the instructions (I think you gave me) for 10l, except water volume,  add to fv and top up fv to 10l with water.

Ferment, condition, drink etc...?

Correct. Just add a bit of the extract before the boil and stir the rest in at the end after the heat is switched off, to ensure it is sterilized in the hot wort.

Thanks for the advice. I'll post my brew day on here when I do it.

10 litre extract Hobgoblin recipe...
Batch Size (L): 10.0
Original Gravity (OG): 1.050
Final Gravity (FG): 1.013
ABV: 4.91 %
Bitterness (IBU): 30
Boil Time (Minutes): 60
1.200 kg Light DME or 1.5kg Light LME
0.200 kg Crystal
0.050 kg Chocolate malt
12.0 g Fuggles Leaf (5.7% Alpha) @ full 60 Minutes
10.0 g Styrian Golding Leaf (4.4% Alpha) @ full 60 Minutes
5.0 g Styrian Golding Leaf (4.4% Alpha) @ last 5 Minutes
S04 yeast

You need to steep the crystal and choc grains for about 30 mins in about 2 litres water around 65-70C. Remove the grains.
Then add the malt extract and more water (make up to 10 litres if you can) and boil for an hour adding hops at the start and 5 mins from the end.
Then cool in the sink and transfer to FV, straining out the hops. top up to 10 litres if necessary.
Pitch yeast when temperature is down to around 20C.

Ah Hobgoblin, that should be good. Steep temperature isn't crucial. Just hot but not boiling. I've read about people boiling their steeping grains though, apparently with no ill effects!

I was planning on following this as closely as possible, especially as it'll be my first extract brew....

You might need to adjust the hopping rate because wort concentration can affect the hop utilisation.

Which is why you just put a bit of extract in the boil, to keep the hop utilization. But also to prevent too much caramelisation and wort colouring.

My thoughts - steep with 2L, top up to 4L add half extract, boil 60mins with hop additions, cool, dilute to 10l adding remaining extract, pitch and ferment...

Just boil as much as you can. Two pans maybe and split the hops.

Pan will hold 6.7L. I could boil 6l with alk extract and top up in fv. 

If I split it over 2 pans would I need to split the steeped wort? 

Would this be easier just making a 5l batch?

No do 10 litres, you should get 5.5 ish litres in the boil. Stick to one pan. If you did two no need to split steeped wort, just put a bit of extract in each. People do 6-10 litre books for 23 litre batches. It'll be fine.
