Changes

A: There are many different opinions on this, but we will state here the best balance between practical and cautious advise. Brettanomyces can be cleaned and sanitized just like regular yeast. Bacteria such as Pediococcus can be a little more hardy, but they also still die from intense cleaning and sanitizing. Maintain a very good cleaning and sanitizing regiment, and you shouldn't need different fermenting vessels if they are glass or stainless steel. Plastic is prone to microscopic scratches, which can help bacteria survive cleaning/sanitizing regiments, so separate plastic fermenters for beers that have bacteria (Lactobacillus or Pediococcus) in them should be considered. Since cold side plastic equipment such as auto siphons and hosing are cheap, it is recommended to go ahead and get separate plasticracking equipment, airlocks, bungs, etc.
