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.
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 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.
Unlike bottles, DIN kegs prevent oxygen exposure allowing reliable carbonation retention for weeks or months. This protects beer taste and quality.
Full DIN kegs weigh under 60 pounds when filled, making them easier to move than commercial Sankey kegs. Their compact shape allows stacking.
Thick stainless steel allows repeated use for years. Kegs can be relined instead of replaced. DIN kegs are a sustainable option versus disposable kegs.
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.
Understanding the diverse range of DIN kegs available is crucial for brewers looking to tailor their setups to specific needs.
The standard DIN keg size, holding approximately 50 liters of liquid, is a common choice for commercial breweries and large-scale events.
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.
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 |
A 5-20 pound CO2 cylinder provides carbonating gas. CO2 is infused into beer at desired volumes to create carbonation.
This device reduces tank pressure to consistent dispensing pressures of 8-15 PSI for faucet systems. A dual regulator can pour two kegs.
Gas and liquid hoses link kegs to regulators and faucets. Quick disconnects allow fast keg swaps.
A coupler attaches and seals kegs to tap faucets for dispensing. Couplers clamp or snap onto DIN valves.
Kegerators are refrigerators outfitted with faucets and hardware for chilled keg tapping. Converted mini-fridges work for smaller kegs.
Thorough cleaning and sanitizing removes residues and bacteria for fresh pure beer. Cleansers like PBW dissolve organics, while sanitizer.
Siphoning with tubing allows controlled, oxygen-free filling. Racking tubes, auto-siphons, or spigots simplify this. Bottom fill for less foaming.
After purging oxygen, force carbonate with CO2 based on style. Seal the lid to contain pressure as the keg carbonates over 1-2 weeks.
Kegs should be cooled to 38-42°F before tapping and while serving. Refrigerate or place in a temperature-controlled kegerator.
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.
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.
Periodically fully disassemble keg components including poppets, posts, valves, and o-rings for thorough cleaning and sanitizing to prevent contamination.
Eventually, gaskets, o-rings, valves, posts, or connectors may need replacing after prolonged use. Kits make repairs easy.
When storing kegs long-term, clean thoroughly and purge all oxygen with CO2 for freshness. Keep sealed at room temp or refrigerated if possible.
Add personalized flair with custom faucets featuring logo handles. Printed keg wraps can brand homemade brews.
For a creamy cascade effect in stouts and more, blend nitrogen and CO2 with a nitro mix regulator. Requires nitro faucets.
Purees, juices, coffee, and more can be added to kegs for infused flavors by using a hop rocket or similar filter container.
DIN kegs are ideal for small test batches of experimental brews. Try new styles, adjuncts, blends, and processes.
Quality ingredients, sanitation discipline, controlled fermentation, and packaging procedures ensure great-tasting homemade brews.
Detailed notes on recipes, processes, carbonation, and evaluations help refine techniques with each batch.
Keep filled kegs cold to minimize aging and prevent light exposure which causes “skunky” flavors.
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.
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.
With the increasing popularity of homebrewing and the growing awareness of the benefits of DIN kegs, the market for these kegs is expected to continue expanding. INOXCVA, a stainless steel keg manufacturing company, is well-positioned to cater to this demand by offering high-quality and versatile DIN kegs for both commercial breweries and homebrewers.
