Oakstills 2 Inch 4 Plate Glass Reflux Still Column
Best for small to mid-size boilers, this 2 inch column uses 4 plates to improve fractionation. The unit fits 2” tri clamp ferrules with an outside ferrule diameter of 2.5”, and is compatible with boilers ranging from 3 gallons to 26 gallons. Constructed from T2 lead-free copper (99.9%) and SS 304, it emphasizes robust build quality, straightforward assembly, and reliable performance. This option suits buyers who want a durable, straightforward setup for vodka, whiskey, rum, grappa, or brandy. A potential limitation is that the system may require careful packing and sealing to maintain consistent reflux, especially on smaller boilers.
2″ 4 Plates Glass Reflux Moonshine Still Column
Best for hobby distillers seeking modular upgrades, this 2 inch 4 plate copper moonshine column is designed for boilers from 8 to 13 gallons. Its modular design supports adding components such as a gin basket, helmet, or extra reflux sections. It combines a sleek aesthetic with practical performance, offering high-quality azeotropic control and flexible expansion. Choose this if you want a visually appealing setup that can grow with your distillation ambitions. A caution: ensure proper fitting of additional components to maintain a tight seal during operation.
2 inch Dephlegmator Still Condenser Stainless Steel
Best for reflux distilling systems needing strong cooling performance, this 2 inch dephlegmator condenser features six cooling pipes for maximum efficiency. It is compatible with a variety of distillation setups, including alcohol distillers and essential stills. The inlet and outlet cooling water port size is 1/2 inch female NPT, which supports common plumbing configurations. Opt for this if you prioritize tighter reflux control and cleaner cuts. A potential limitation is that it may require additional components to integrate seamlessly with some boilers.
2 inch Glass Reflux Column Section with Copper Bubble Plate
Best for copper-enhanced aroma and visibility, this section includes a copper bubble plate made of 99.9% lead-free copper with a stainless steel sight glass and borosilicate glass. It comes complete with a bubble plate, sight glass, clamp, and gasket, and fits 2 inch tri clamp ferrules with a 2.5″ outside diameter. This option is ideal for distillers seeking increased copper contact for smoother flavors, while keeping the process observable. A caveat: ensure compatibility with your existing column height and seals to prevent leaks.
Tubular Distillation Tower With Sight Glass
Best for larger fermenters, this 2″ stainless steel modular column supports 13–26 gallon boilers. It includes a sight glass for monitoring and a thermometer to observe temperature along the tube, aiding precise control. Copper mesh is used to accelerate spirit aging and improve aroma by adsorbing tramp alcohols. This option suits distillers who want an integrated system with enhanced visibility and copper-driven flavor development. Limitation: copper exposure requires routine maintenance to prevent tarnish and ensure consistent performance.
2 inch Modular Pot Still Column
Best for upgrade paths, this 2-inch stainless steel pot still column emphasizes modularity and seamless component integration via tri-clamp ferrules. It is designed to work efficiently with boilers from 8 to 26 gallons. An included screen gasket supports packing materials for improved distillation control. Choose this for a versatile foundation that can accommodate future expansions like gin baskets, reflux sections, or whiskey helmets. A note: ensure your chosen upgrades maintain thermal efficiency across the entire setup.
2 inch Moonshine Still Column Type-A
Best for mid-size to larger boilers, this modular column uses tri clamp ferrules and supports a variety of add-ons such as gin baskets, whiskey helmets, and extra reflux sections. It is intended for boilers ranging from 20L to 100L, making it a solid option for builders aiming for greater flexibility and higher output. Limitations may include the need for precise assembly and potential adjustments when adding multiple accessories to maintain optimal reflux.
2 inch Stainless Modular Moonshine Still Column Multifunctional
Best for a broad range of distillation tasks, this 2 inch stainless modular column fits 2 inch tri clamp ferrules and supports boilers from 8 to 26 gallons. Designed for high-proof alcohol and neutral spirits such as vodka, gin, brandy, whiskey, and various moonshines, it emphasizes modular compatibility with components like gin baskets, whiskey helmets, and extra reflux sections. A limitation is that the modular nature requires careful planning to maintain airtight seals as you add components.
Buying Guide
What to consider when choosing a 2 inch reflux column
- Boiler size compatibility: Confirm the boiler range for your setup (e.g., 3–26 gallons, 8–26 gallons, or 20–100 liters) to ensure efficient operation.
- Modularity vs. fixed design: If you want to upgrade over time, prioritize columns with tri-clamp ferrules and compatibility with accessories like gin baskets, reflux sections, or helmets.
- Material and finish: Copper components often enhance aroma and aging, while stainless steel provides durability and easier cleaning.
- Cooling and reflux control: Look for condensers or dephlegmators with multiple cooling pipes and reliable seals to manage reflux effectively.
- Visibility and monitoring: Sight glass and thermometer options help you monitor progress and adjust temperatures precisely.
- Ease of assembly: Modular systems should offer straightforward assembly, with clear seals and gasket compatibility to reduce leaks.
How to compare quickly
- Best for small setups: 4-plate glass columns with solid copper components for flavor and clarity.
- Best for upgrades: Modular columns with tri-clamp ferrules and compatible accessories.
