What an awesome product, first brew already in and loving watching the krausen bubble away. Fermzilla turned up exactly when they said it would. If you buy this also order a spunding valve so you can brew under pressure straight away.

Fermzilla - the downside

I recently purchased a fermzilla from iKegger. The delivery and service form iKegger has always been great. I have bought equipment from them on 4 separate occasions now. I have nothing bad to say about them. The Fermzilla is a great product, this is the first dedicated pressure fermented I have used. Previously I have use corny kegs for pressure fermenting. I love everything about the Fermzilla except for a few small things. There is a massive warning written on the side that states it is not to be used for pressure fermenting past Nov 2021. I bought this product in March so by the letter of the law, it lasts 20 months. While this ferment er is cheap, I don't want to be purchasing a product every few years. it seems a little wasteful. My second problem is one of the O-rings is missing. They send a pack of spares in the box so it's not a massive problem. But now i don't have any spares. This is still a great value for money product, however if you have the means, a stainless steel ferment er will cost less in the long run. As a side note, I can't rate corny keg fermenters enough. They fit in the fridge, have handles and already set up for pressure transfers. The Corny will always be my go to fermenter for small batches.

This is a great item for the price. It functions as described, easy to clean(i recommend soaking and not scrubbing as it will scratch the plastic and Bacteria can hid in these groves). The only negative I found is it's susceptible to light, As it's clear plastic you should already be aware of this. I brew in a fridge and check things at night so no ill effects. There's no better pressure capable fermenter for the price on the market

Fermzilla 27L - Great product and great service from iKegger

I haven’t got around to using the fermzilla yet, but it gets 5 stars for build quality - much better than I was expecting, holds pressure, and fits perfectly in my fridge. Can’t fault the iKegger service either - would buy from them before I even look at kegland next time!
