Changes

Most brewers will advise that if it all possible, try not to disturb the pellicle too much when taking a sample, racking, or moving the fermenting vessel. If taking a sample or racking, gently pierce the top of the pellicle with the racking cane or wine thief. If the pellicle does break up, don't worry too much. It will usually reform if oxygen is still present in the headspace. While packaging the beer, try not to disturb the pellicle too much because the clumps of the pellicle on the surface of the beer can fall back into solution when disturbed, and can then get transferred into the bottles or kegs.
