Would thier be any bad off flavors or worse if I were to combine two liquid malt extract kits to make one beer, or would it just make it more malty & stronger. I would double pitch the yeast & use a blow off tube.
They do this a lot down under,it's called a "toucan" (two can). They use both yeast sachets,since they're only 7g. Not like the 11.5g packets over here. so use both,trust me.
1.10 sounds really big for one pack of yeast even if it was 11g. I would go ahead and pitch the other pack. Otherwise you will be under pitching. I hope you aerated well.
2 cans is 7.5LBS of liquid malt - it should not give you a 1.1 reading for a 5 gallon brew. Chances are it was a misreading - possibly the malts were not fully mixed.Im sure it will turn out fine though.
