Stupid question, but if i'm converting a recipe for 5 US gallons to 5 UK gallons, do I just multiply the entire recipe (grains, hops, extract) by 1.2? Will boiling an extra US gallon of water change the utilisation of hop bitterness too much or should I add it after the boil?

Thanks
 
NO, scale everything.

Hops utilization depends of concentration. so if you boil it in a more concentrated wort and add watter to the fermenter, the IBU will be lower than expected (though not that different).

so scale up all the ingredientes including boiling water.

Nice one, thanks. Don't let anyone tell you the metric system is a good thing ;)

Actually I'm an argentinian living in the USA, and there is no way someone can convince me the british system is better than the metric... :D

but as I learned to brew here I use the metric system for everything, except for brewing ;)

As they say: when in rome do like the romans do :eek:
