DIN kegs are a specialized type of stainless steel keg conforming to a German national standard for dimensions and fittings. With the right accessories and techniques, DIN kegs can be used by homebrewers to store, carbonate, and serve homemade brews. This guide will provide an overview of DIN keg components, equipment needs, keg preparation, serving, maintenance, and troubleshooting tips for beginners venturing into kegging their craft beers.

What are DIN Kegs?

DIN kegs are cylindrical stainless steel kegs that comply with Deutschland Institut für Normung (DIN) specifications 6647 for standard keg dimensions and DIN 6635 for screw-in valves and fittings. This ensures consistency across DIN-compliant kegs from various manufacturers. The thick stainless construction resists corrosion and protects contents.

The Rise of Homebrewing and DIN Kegs

The homebrewing market is experiencing steady growth, with a projected compound annual growth rate (CAGR) of 8.5% from 2021 to 2028, reaching a revenue of $28.8 billion by 2028 according to Grand View Research. This surge in interest creates a growing demand for equipment like DIN kegs, which offer several advantages to homebrewers.

The Rise of Homebrewing and DIN Kegs
Consistent Carbonation

Unlike bottles, DIN kegs prevent oxygen exposure allowing reliable carbonation retention for weeks or months. This protects beer taste and quality.

Portability

Full DIN kegs weigh under 60 pounds when filled, making them easier to move than commercial Sankey kegs. Their compact shape allows stacking.

Durability and Reuse

Thick stainless steel allows repeated use for years. Kegs can be relined instead of replaced. DIN kegs are a sustainable option versus disposable kegs.

Versatility

From five-gallon kegs to three-gallon “sixth barrel” kegs to one-gallon mini kegs, DIN kegs come in many sizes to suit needs. Custom graphics can be added.

DIN Keg Sizes and Styles

Understanding the diverse range of DIN kegs available is crucial for brewers looking to tailor their setups to specific needs.

Common Full-Size Kegs

The standard DIN keg size, holding approximately 50 liters of liquid, is a common choice for commercial breweries and large-scale events.

Mini Kegs and Slim Quarter Kegs

For smaller gatherings or homebrewers, mini kegs and slim quarter kegs offer convenient alternatives, maintaining the benefits of DIN technology in a more compact form.

Wide Range of Specialty Kegs

DIN kegs come in various styles, including slimline, tall, and stackable variations, catering to specific requirements and providing options for diverse brewing styles.

PRODUCT CAPACITY (L/GAL) DIAMETER (D) (MM/IN) TOTAL HEIGHT (H) (MM) WEIGHT (KG/LBS)
20L DIN 20 / 5.283 365 / 15.55 300 8.5 / 18.84
30L DIN 30 / 7.925 365 / 15.55 365 10 / 22.04
50L DIN 50 / 13.21 365 / 15.55 590 11.4/25.13
Equipment Needs for DIN Kegs
 Equipment Needs for DIN Kegs
CO2 Tank

A 5-20 pound CO2 cylinder provides carbonating gas. CO2 is infused into beer at desired volumes to create carbonation.

Regulator

This device reduces tank pressure to consistent dispensing pressures of 8-15 PSI for faucet systems. A dual regulator can pour two kegs.

Hoses and Connectors

Gas and liquid hoses link kegs to regulators and faucets. Quick disconnects allow fast keg swaps.

DIN Keg Coupler

A coupler attaches and seals kegs to tap faucets for dispensing. Couplers clamp or snap onto DIN valves.

DIN Kegerator

Kegerators are refrigerators outfitted with faucets and hardware for chilled keg tapping. Converted mini-fridges work for smaller kegs.

Getting Your Homebrew into a DIN Keg
Cleaning and Sanitizing

Thorough cleaning and sanitizing removes residues and bacteria for fresh pure beer. Cleansers like PBW dissolve organics, while sanitizer.

Filling Techniques and Tips

Siphoning with tubing allows controlled, oxygen-free filling. Racking tubes, auto-siphons, or spigots simplify this. Bottom fill for less foaming.

Carbonating and Sealing

After purging oxygen, force carbonate with CO2 based on style. Seal the lid to contain pressure as the keg carbonates over 1-2 weeks.

Tapping and Serving from DIN Kegs

Cooling and Storage

Kegs should be cooled to 38-42°F before tapping and while serving. Refrigerate or place in a temperature-controlled kegerator.

Setting Up Kegerator System

Attach gas lines, beer lines, and coupler fitting snugly. Ensure proper temperature. Adjust regulator pressure and pour a test pint to dial in your pour.

Achieving Proper Pour and Head

Ideally, beers pour clear without foaming using 6-10 feet of 3/16 inch beer line and correct pressure around 12 PSI. Adjust as needed.

Cleaning and Maintenance
Disassembly and Cleaning

Periodically fully disassemble keg components including poppets, posts, valves, and o-rings for thorough cleaning and sanitizing to prevent contamination.

Replacement Parts

Eventually, gaskets, o-rings, valves, posts, or connectors may need replacing after prolonged use. Kits make repairs easy.

Long-Term Care

When storing kegs long-term, clean thoroughly and purge all oxygen with CO2 for freshness. Keep sealed at room temp or refrigerated if possible.

Advanced DIN Keg Techniques
Custom Tap Handles and Branding

Add personalized flair with custom faucets featuring logo handles. Printed keg wraps can brand homemade brews.

Nitro Brewing with Nitrogen

For a creamy cascade effect in stouts and more, blend nitrogen and CO2 with a nitro mix regulator. Requires nitro faucets.

Adding Flavorings

Purees, juices, coffee, and more can be added to kegs for infused flavors by using a hop rocket or similar filter container.

Experimental Brewing

DIN kegs are ideal for small test batches of experimental brews. Try new styles, adjuncts, blends, and processes.

Tips for DIN Keg Success
Following Brewing Best Practices

Quality ingredients, sanitation discipline, controlled fermentation, and packaging procedures ensure great-tasting homemade brews.

Record Keeping

Detailed notes on recipes, processes, carbonation, and evaluations help refine techniques with each batch.

Proper Storage Conditions

Keep filled kegs cold to minimize aging and prevent light exposure which causes “skunky” flavors.

Investing in Quality Equipment

Spending more upfront for robust regulators, seals, fittings and taps prevents problems down the road and improves the brewing experience.

DIN kegs provide homebrewers with a versatile and reusable way to enjoy their beer on draft while protecting and presenting it at its best. Follow this guide to understand DIN keg components and functionality, equipment required, keg preparation essentials, tapping and serving techniques, and maintenance best practices. Mastering kegging skills takes your homebrewing to the next level.

Market Demand for Different DIN Keg Sizes
Market Demand for Different DIN Keg Sizes

While the standard 50L DIN keg remains popular for commercial breweries and large events, the market shows a growing preference for smaller kegs among homebrewers:

A 2021 survey by the American Homebrewers Association revealed that 28% of homebrewers in the US use all-grain brewing methods, often producing larger batches that might suit the 50L kegs.

However, the survey also found that 40% of homebrewers started the hobby within the last four years, and these new brewers might be drawn to smaller and more manageable keg sizes like the mini kegs and slim quarter kegs mentioned in the blog.
