Agree with Frodo - of course you would rather have everything ultra clean but everything is going OUT. So once the blow off is calmed down just put the air lock on it.
Grinders Island Brewery - Pipeline
Bottled! Award winning East India Porter, Oatmeal Stout, Milk Stout, Saison fermenting at a nice controlled 85 degrees (up from 70) as it should be - weird isn't it.
