is 8g of priming suger /litre too much?

[guyb]

Hello all, the Coopers Mexican Cerveza is according to the instructions ready to be bottled, the OG was 1042 and it's now down to 1011. (unfortunately I may have been a little enthusiastic when doing the wort, and added about 2litres of water too much :hmm: - lesson learned). The current fv capacity marking doesn't go past 20L on it's scale, whereas my second fv goes up to to 23L (so I might not yet have over watered).

The instructions say that I should use 8g of sugar per litre for bottling - I am intending batch primaing in a 2nd FV immediately beofre bottling.

If I have 25L, I make that I need 200gr of priming sugar and obviously if I have 23L I'll need 184gr.

Do either of these sound on the high side? I've been reading a few posts where 100~125gr seems to be the norm, and some as low as 60~80gr.
I did look at a carbonation calculator, and selected American Light lager at 2.6volumes (as a guess as this was the closest thing I thought resembled Cerveza), with ordinary can sugar the dosage came out at 152gr for 23L and 165gr for 25L both at 20degC.

Bottling in 1L PET bottles btw.

Should I just follow the instructions on the kit?

any advice gratefully received.

It comes down to one question - how fizzy do you like your beer? :thumb:

I'd advise to err on the side of caution and use less, rather than more.

opening a bottle and carefully pouring the beer only for it to froth up so that the glass ends up 2/3rds full of froth, frankly sucks

It's your call, but I'd say no more than 120g for the full batch, prefferably less - but that's my personal preference coming in, maybe not yours :whistle:

AS AN AWARD WINNING BREWER MY ADVISE WOULD BE...... Sorry that will be the one and only time I will use that phrase :rofl: :rofl:

I believe the Cerveza is a Lager type beer so will be served cold and is supposed to be more on the fizzy side. I use 3g per 500ml bottle in an Ale. So that would be 6g per Liter so I suppose 8g per liter would not be unreasonable. As it will be served cold it should absorb the extra CO2 and not fizz out of the bottle like a warmer served ale would at that carbonation level. Just my take on things and I may be totally wrong.

8g per litre is absolutely fine for a fizzy beer/lager.

Absolute minimum chance of the PET bottles exploding anyway even if you do over prime them, they can withstand a huge amount of pressure.

Thanks for all the replies, all primed up now, I went fo 8g/L in the end, two sugar lumps per
bottle as per the instructions, as I like a bit of fizz in lager. Time will tell,'all part of the experience
