Default ****! Forgot to aerate!

Oh I think I am in deep trouble. I have done a pilsener (from the Cooper's Pilsener Kit) and I somehow forgot to aerate my wort! I really hope that there won't be any problem with stuck fermentation.

What do you guys think?

How long ago did you pitch the yeast? Is it actively fermenting yet? If it isn't just shake it up.

Several hours before I remembered. The krausen is already fully blown, so should I start to aerate now?

No, if it's going you don't want to add any oxygen now. If your yeast has a high enough cell count and is healthy, you should be alright.

What was your OG. If it's on the low side of 1.055, you'll probably be OK. But you may need to pitch again if it sticks.

(Warning: Advice from a noob coming up ...)

If the fermentation sticks try adding a microscopic amount of olive-oil; say dip a piece of wire in the oil then into a small amount of water, boil then pitch. This can replace aeration; my understanding of the process is that aeration is necessary for the yeast to produce lipids during the initial growth phase; the olive-oil provides these directly so the yeast can skip that step. Discussion here and elsewhere, the full paper that started it all is here. Apparently some breweries (Struise?) now use this method exclusively.

The olive-oil trick only works in a starter, once you've pitched it won't make any difference.

If there's krausen, RDWHAHB. Your beer is fermenting. Don't go shaking it around or adding stuff to it now.

Did you do a full boil, or did you do a partial boil and then top up the fermenter with water? If you topped up, there will be oxygen in the water you add, so that will help.
