Speidel 30L (7.9 Gallon) Plastic Fermenter with Spigot, Bung & Airlock Review (2026)

Who this fermenter is for

The Speidel 30L, sold in the US as a 7.9 gallon fermenter, targets homebrewers who have outgrown a basic plastic bucket but are not ready to buy glass or stainless. Its 30 liter capacity gives a standard five gallon batch enough headspace that a vigorous krausen rarely needs a blow off tube, which is a common complaint with tighter fermenters. Wine and cider makers who work in five to six gallon batches also fit the sizing well, since the extra volume absorbs foam from primary fermentation without spilling out the airlock. Because the vessel is opaque, it blocks light that would otherwise skunk beer or degrade delicate wine aromas, so it works for both short primary fermentations and longer secondary aging when a brewer wants to rack off sediment before bottling.

Build and what comes in the box

Speidel is a German manufacturer better known for large commercial wine tanks, and that background shows in the fermenter's build. The body is molded from thick, undyed HDPE plastic rated for warm liquids, so it resists the oxygen transfer that thinner buckets allow over long aging periods. The lid uses a screw and lock design with a gasket seal, which holds a tighter fit than a snap on bucket lid. Every unit ships with a rotating spigot for racking without lifting the fermenter, a rubber bung, and an oversized two piece Speidel airlock, so a brewer has a complete fermenting setup out of the box rather than needing to source parts separately. Molded handles on the sides make the roughly 13.5 inch diameter, 18.5 inch tall vessel manageable to move even when full of liquid.

Living with the Speidel day to day

Setup is straightforward: rinse and sanitize, pitch yeast, seal the lid, and fill the airlock. The spigot is the standout convenience feature, letting a brewer rack finished beer or wine straight into a bottling bucket or carboy without siphoning or lifting a full fermenter onto a counter. The trade off shows up at cleaning time. The screw top opening is narrower than a wide mouth bucket, so scrubbing dried krausen residue off the shoulder of the vessel takes more effort and a bottle brush with a long handle. Owners in retailer listings and forum discussions describe the plastic as thick enough to resist scratching from normal cleaning, which matters because scratches in fermenter plastic can harbor bacteria over repeated use. The molded handles help when carrying a full 30 liter fermenter to a cooler spot for temperature control.

Trade-offs and how it compares

Against a basic plastic bucket, the Speidel costs more but earns that premium with a proper spigot, a locking gasketed lid and German build quality, rather than a snap lid and a hole a brewer drills themselves. Compared with other fermenters in this class, it lands in the middle of the field: it does not have the built in pressure capability of a keg style fermenter, and its narrow neck is harder to clean than a wide mouth bucket, but it beats basic buckets on light protection and seal quality. Brewers who plan to dry hop through the lid opening or need to physically reach inside to stir will find the screw top mouth more restrictive than a bucket's full width lid, so it suits a mostly hands off fermentation style better than one with frequent additions.

Verdict and who should look elsewhere

The Speidel 30L earns our score of 8.5 out of 10 as a durable, well sealed step up from a basic fermenting bucket, and it is a strong pick for five gallon beer brewers and wine or cider makers who want reliable headspace and an integrated spigot. Brewers who add dry hops, fruit or oak chips mid fermentation and want easy hand access should look at a wide mouth bucket instead, since the narrower Speidel opening makes those additions and the follow up cleaning more work. Anyone chilling with counter pressure kegging in mind should also look at pressure capable fermenters instead, since this vessel is a standard atmospheric design.
