my 30 liter speidel fermenter arrived yesterday and i'm pretty excited about these tanks, when the 60 liter tank is back in stock i'll probably get that size too.
this seal thing goes in first then a threaded ring goes over top
i didn't take a picture of the hole on top but it's about 1 1/2 inches. you can seal off the bottom drain with a cap and siphon from the top or use the included spigot.
a bit wider than an ale pale and with the airlock on it's a bit taller. during the winter months my garage stays pretty cool so i plan on fermenting on my work bench. during the summer i might have to use a blow off tube instead of the airlock to fit it into my mini fridge.
the biggest airlock i've ever seen.
i was worried about the height of the drain on the bottom but it looks to be a non issue. i measured about 1 1/4 inches from the bottom up to the level of the drain so there should be plenty of room for the trub to settle down in without making it into the bottles. if it is an issue the inside of the spigot can take a stopper and some sort of dip tube but i doubt i'll have to do this.
when i brew again next week i'll put this tank to the test to see if it performs well as a fermenter/bottling bucket.
