Check out the video above for my Speidel Fermenter review. I bought the 30L version from MoreBeer, which is 7.9 gallons. The next size down is 5.3 gallons which is a little tight if you're doing 5 gallon batches. Personally, I do 6 gallon batches with 5.5 going into the fermenter, so the 30L version was the best option.
As I tell you in the video I'm very happy with the Speidel Fermenter. It's a really great piece of homebrewing equipment. Among its best features are:
- Large mouth opening for easy cleaning
- A spigot at the bottom for quick & easy transferring
- Heavy duty HDPE plastic
- Has handles
My biggest knock against it is that it's not clear – something I like about my plastic carboys. I've also read that some people have rough/sharp spots in theirs where the neck meets the main part. I don't have that in mine – there is a seam there but overall it's pretty smooth. Another knock is that the airlock constantly gets stuck in the rubber stopper and it's not easy to remove.
However the pros outweigh the very few cons about this fermenter and I highly recommend it.
Let me know if you have questions about it or if you own one yourself, let me know what you think down in the comments.
