So I have tried all sort of fermenters.I have started with glass. Easy to see/clean, but have to be careful (use box crates at all times!) and difficult to add a lot of hops or other additions.Plastic buckets are the cheapest and worst solution in my opinion. Can never trust those lids to close properly, air could always get in over time. Scratches in plastic walls will start harboring bacteria, and transfer from bucket is a mess, in my experience (can never guess where trub line is).In fact, for this reason, the fermenter should be transparent. I tried fermenting in kegs too, and it's the same issue. I need visual cues of fermentation process and see what I am transferring.Better bottle IS better, fairly easy to clean (just fill with warm water and oxyclean - don't use brush!), transparent, light, won't shatter. But opening is a bit too small for hopping and oak etc. And volume is too small - worry about blow-off tubes etc.7G Fermonster solves all these problems. Larger size (more like 7.5G really) means rising krausen won't cause a "beer volcano" when you fill 6 or even 6.5G of beer. Huge, I mean YUUUGE opening means you can easily add hops, fruit, oak and take them out too (with glass and better bottles you may have to leave the bags in once it adsorbs water). And easy to clean too. And still transparent and safe.The lids close very securely, thanks to O-ring system and if you drill an extra hole in a stopper you can do closed transfers just as easily as with better bottles or glass, using sterile siphon.
