Silly question ?

Has anybody any experience of trying to boil on the stove top ?

I would like to brew 2 cornies worth of mild (40 L) this week but my only way of boiling would be to use this 50L stockpot on the stove.
Anybody got any ideas how long it'd take to bring to the boil, is it worth doing ?

I boiled on an electric hob for a while, only 25L brews and it took quite some time to reach boil. I'm not sure i'd like to wait for 40L to boil on my cooker anyway Could you use 2 rings on that cooker under your pot? If you could i'd imagine you'll manage but i've no idea how long it might take.

I've done cereal mashes and Decoctions on the stove top (Probably around 20L max) and its not all that successful even using two rings . . . Wort boiling . . . You might get away with, but it will take a while to come to the boil

As an alternative would I be right in assuming that if I mash and boil 25Lof a higher gravity beer I would be ok to liquor back to give myself 40L?
I understand that I would need to use a higher amount of hops in a higher gravity wort to achieve my target bitterness and use dechlorinated water to dilute with but are there any obvious drawbacks?

This is what I am thinking of for 40L of mild
OG 1.036 IBU 15

4.5kg pale malt
1kg crystal malt
250g black malt
200g chocolate malt
500g soft brown sugar

35g Northdown 7.5% aa 90 min boil

Mash and sparge to collect 30L topping up with spare wort during boil.
Chill as usual, and dilute to 40L before pitching the yeast.


What do you think ?

You may have trouble getting the wort to boil vigourously which may affect the hot break

I've always boiled in a 36L stockpot on the electric hob, straddling the rounds. With all the rounds on full, 30 litres of cold tap water takes about an hour to boil, I've found. Of course, you'd be rather silly to put your wort in that cold (at least more than once!).
I suppose it depends on your cooker, but ours certainly isn't top-of-the-range and it gets a fair boil going: no problems with hot break etc.
