Im brewing a big IPA, and my OG is around 1.074, and the recipe states that its about 1.064-1.068. Total noob question, and I searched, but didnt really find anything about 1) what happens to the end product when the OG is high, and 2) when is high too high?

higher OG means more alcohol, usually. Over 1.120 the osmotic pressure becomes pretty high, but manageable. I'd say 1.150 would be the point where the yeast is really gonna struggle.

Also, 1.074 isn't really a "big" beer, at least not by my standards.

Your OG shouldn't be an issue, at all but you are approaching the high side for an American IPA.

What you want to focus on is whether you pitched or built up enough yeast, to take on a 1.074. Likely, one smack pack, tube, or dry yeast pack won't get it done.

For more info...go to mrmalty.com...

Cheers!

Your still within the style guidelines for an IPA so I'd say roll with it.

I'd make sure I pitched enough yeast though.

According to Mr. Malty about 254 billion cells.

Sorry, lucybear999 you beat me to it.

It'll be just fine. WLP007 is a beast.

It will change the BU/GU balance, but I wouldn't worry about an extra 6 points.

Havent seen my fermenter since i finished brewing at 7 last night, 15 hours in and fermentation took off. First time using a glass carboy, what a sight

Edit: 27 hours, I didn't include half a day due to carboy excitement
