Hi i was wondering if when you buy a fresh 5ltr pet bottle off water and are going to empty the water out and start a brew do you need to sterilise the bottle first or is it ok as it had the water in it ? After racking off can you store the wine in a 5ltr pet bottle instead of glass bottles with corks ? And last but not least what is gp yeast is it different from ordinary wine yeast ? :hmm:
