120g table sugar for the IPA in say 22 litres will put you at the low end of the carbing range, but I'm sure that will be fine.Primed with 120g so hope that is ok, gonna prime an irish stout tonight. Brewed short at 19 litres as you have done yourself 90g prime sugar?
Cheers

I use 90 - 95g table sugar in my stouts cos they go into plastic PBs and that's the limit.
However it works, and looking at the calculator would be fine for bottles too.
