Hands on Review: Oktober Design SL1 Can Seamer – Can Your Homebrew!

Oktober Design was started in 2014 by a group of engineers and beer lovers. They make high quality, well thought out and affordable Crowler and Can seamers.  Their target has been brew pubs and smaller commercial brewers. With the introduction of the SL1 they’ve finally made a machine designed specifically for homebrewers.

Before Oktober Designs and similar started making countertop can seamers, canning beer was out of reach and unrealistic for homebrewers and even some smaller brew pub operations.  I looked into canning early in my homebrewing career. Around that time a manufacturer released an “affordable” system that was in the $10k, range. That was considered affordable at the time. I’m happy to say that times have changed.

Why Can?

Cans block all light and oxygen transfer. That’s not true of bottles. They also play well at the park, beach and pool. Glass bottles are made from breakable glass that can… break. 🙂 Canning is also… cool. We’ve been able to pretty easily do everything that commercial brewers have been able to do – Conicals, Control Panels, Fermenting Under Pressure and More – for quite some time. Canning, until recently, was a hold out.

Even with new equipment like the SL1 becoming available, canning is more expensive than bottling. You can save used bottles for free and use a $10 capper. This means that doing things as cheap as possible cannot be a driving factor when considering a can seamer.

How to Fill Cans for Use with Homebrew

Of course, you can fill cans with uncarbonated beer, add priming sugar and naturally carbonate. My assumption is that if you’re going to make the investment in a canner, odds are good that you’re probably kegging. So, let’s talk about a few ways to fill cans from a keg.

These are in order from least sophisticated to most sophisticated.

In the boxHow mine came out of the box. The only real setup was removing the tape from the bottom lever, installing the top lever and wiping down the SL1 to clean up some lubricant and dust.Front view. The SL1 has two levers. The bottom lever raises the filled can up and locks it in place. The top lever seals cans.Close up of the top part of the cannerSide viewClose up of the on/off switch. This is engaged and disengaged each time a can is seamed.Close up of the motor. The SL1 is… BEEFY. It’s for homebrew use, but you can tell that it comes from commercial roots. I’m not a motor-size expert sort of a person :), but I feel like they could have gotten away with a smaller motor. The SL1 has plenty of power and the whole setup just seems well put together.Stuff that comes with it… seamer lever, food grade lubricant, some stickers and the manual manual (link to PDF manual below).  The seamer lever comes uninstalled and easily screws in place.

Three Positions to Seam

The SL1 top lever has three general positions.  Position 0, 1 and 2. Working through those positions while a can is locked in place and spinning seals the can.

Position 0, what I would call neutral, the level is facing forward-ish, in the middle of positions 1 and 2.Position 1, far rightPosition 2, far leftPositions as described in the manual

Cans and Lids

The SL1 can seam 12 and 16 ounce cans. Sadly, it cannot seam Crowlers. I got 16 ounce cans.When I first looked into canning, empty cans were sold by the… truckload. Or some other similarly massive quantity. Oktober Designs sells cans in homebrewer-friendly quantities. They are available blank and can also be customized. The SL1 will also seal compatible cans from other sources.  Check out the Tips section below a tip on getting economical empty cans.My cans feature a Drink Local Design and have an area write details about the Beer.These also feature a government warning, which may or may not be helpful or applicable where you live.

More About Compatible SL1 Compatible Cans and Tops

The Oktober SL1 Homebrewer Can Seamer is designed to seam aluminum beverage cans with size 202 ends (tops) with the B64 style profile. SL1 Homebrewer comes standard with adapters for 16oz and 12oz cans. Because the seamer shares the same upper and lower chucks and adapters as Model 7 – B can seamers, it can optionally be set up for CDL and SuperEnd® (360 end®) profile ends (excluding size 200 ends), as well as optional can sizes like 500ml, 8oz “stubby”, etc.

Seaming Cans with the SL1

Sealing Cans with the SL1 is… easy.  It’s a matter of putting a filled can and top in the seamer, locking the can in place, turning the seamer on and running through three lever positions.

If you look closely, there’s a problem here. See the Tips section for more.

SL1 for Commercial Brewers?

When explaining the differences between their Model 7 and the SL1, Oktober Design says… “The SL1 was specifically designed for less frequent use and requires a bit more routine maintenance, making it less ideal for commercial applications.”

Lessons Learned & SL1 Seaming Tips

My first can seam was a fail.  After my first fail I… opened the manual. After reading the process and three positions, my second can seam was perfect and… easy.

As I continued, I started getting some bad seals and some slight can crushing.  It was maybe every other can and it was frustrating. Upon closer inspection, I was grabbing two tops. When I realized this, things were great again.  If you look closely in this photo, you’ll see the can has two tops. So, this was an easy fix… one top per can.


  • Plan on doing a few test cans before moving on to beer or cider.
  • Fill test cans with water, empty cans have a tendency to crush.
  • Tops can stick together, make sure you’re just getting one.
  • Much like one of our tips on getting the best deal on a sack of grain… make friends with your local brewery and they just may give you a great deal on unlabeled cans to use with your SL1.
  • Any easy way to do a quick check of how your cans are sealing is to squeeze a sealed can.
  • When you’re seaming a few cans to take to a get together, cleanup will generally be quick and easy. A quick wipe down of your SL1 and table. If you’re going to can an entire batch it may be helpful to use a tray or tub to catch drips. If you’ve read Homebrew Finds for long, you know I use these bus tubs (pictured below) for lots of things around the homebrewery.

I’ve been wanting an Oktober Design Can seamer for years. It did not disappoint. It’s super well built and (after reading the manual) easy to use and reliable.  It is an investment, but I’m excited that Oktober Designs has come out with a model designed specifically for homebrewers. Is the SL1 a must-have? No. But, if you’re looking to treat yourself and want your beer to look awesome, the SL1 from Oktober Designs is worth a hard look.
