Batch priming a porter

[howyoubrewin]

Hi folks,I am planning to make a chocolate & vanilla porter this week from a recipe that i threw together and i am unsure on the level of carbonation expected from this type of beer as i haven't brewed one like it before. It will be a standard 23L batch,maybe reduced to 21L and I would ideally like to batch prime.
Can anyone give me an idea of how much priming sugar to use on this type of beer?
Cheers n beers! :

The choc and vanilla porter I've got carbing up at the minute is primed at 4g/l.

Around about 80-90g would do then?

Yes mate

80-90 will be fine, middle of the road fizz. I use more as my other half likes fizzy beer, up to around 120 for 23l, but that's a lot, esp for a stout.
Once you have made this batch you can decide whether to do a little more or a little less next time. Good luck.

In addition to my last query,i plan to add 1.5 oz vanilla extract at beginning of fermentation and another 1.5 oz before bottling. Does this sound about right for a subtle but noticeable vanilla flavour?
Cheers

I added 75ml at bottling but couldn't tell you yet how its turned out.
