Low OG

[BelfastBrewer]

Hey, ive just started home brew. My first batchs OG was only 1.028 and I got the FG at 1.006 so it's a pretty low ABV. I think I added too much mineral water to the wort before fermentation.

Any advice for the future? :wha:

You've got to look at your mash....time, grain to water ratio, sparge. Tell us want you did on your brew day.

was the wort hot when taking the og reading? if so it wouldnt be the correct reading there are gravity/temp calculators here on the forum. :)

I used 3.5 kg of malt, to around 15 Liters water(3kg of pale malt & .5 of crystal) I mashed for 1 hour and then sparged about 2 liters

The wort wasn't hot, maybe 30 c at most, My fermentation was also vigourous the 1st day and then slowed way down

The usual advice given in the UK is to mash at a 2.5:1 ratio. So about 9L might have given you a slightly higher efficiency.
