First BIAB

Add water to bring in back nearer where you were aiming.
You made beer, not the beer you wanted but probably decent drinkable beer.

Split the batch and then dilute it with cooled boiled water back to your original (or desired) original gravity.

Brewmate has some calculators for adding water to reach desired gravity.

1070 is a high concentration of wort and chucking in a pack of dried yeast may end up struggling to ferment it out to proper final gravity due to yeast struggling in a high alcohol environment.

You could put a different yeast in each batch so see how yeasts affect final taste.

The approach suggested by Yum beer and angus is probably the way to go. They picked up on something I missed. You have a recipe with hopping for a beer with a SG of 1040. The much higher gravity will change the balance of the beer significantly. By diluting back to the originally intended gravity the bitterness should be more in line with the recipe.

Ok thanks
I've got 2 fermenters so will give it a go plus the different yeasts

 

[meathead]

Well this has been fermented, bottled and taste
It's a little bland, I'm assuming because the hops vs volume ratio changed so much with the water addition
It's drinkable, more like commercial megaswill
But we've all got mates who like megaswill so it will find a good home

Thats the spirit. You've made beer with your first brew, you cant argue with that.

What you have to do now is learn from any mistakes you've made. Thats where it gets difficult
