I was looking at a plastic collapsible fermenter and was thinking it would be a great way of avoiding the dilution effects of topping off or needing to have extra juice/wine on hand to top off with when you rack . Are there any disadvantages to these containers? I figure you just collapse the container untill there is no more head space and move on. The one I'm looking at is $10.49 for a 5 gallon container. What is your experience?
