How to make a concrete tank for wine

Concrete tanks have become increasingly popular in the winemaking industry due to their numerous benefits. Not only do they provide a stable temperature and humidity environment, but they also offer excellent insulation properties and superior resistance to bacteria and oxidation. If you’re an aspiring winemaker looking to create your own concrete tank for wine, here is a step-by-step guide to help you get started.

1. Design and Planning:
Before beginning the construction process, you need to have a clear understanding of the size, shape, and location of your desired concrete tank. Consider factors like the quantity of wine you intend to produce and the space available on your winery premises. It’s essential to have accurate measurements and a solid plan in mind before proceeding to the next step.

2. Materials and Tools:
To create a concrete tank, you will need the following materials and tools:

– Reinforcing steel bars (rebar)
– Plywood or metal sheets for formwork
– Cement
– Sand
– Gravel or crushed stones
– Water
– Concrete mixer or wheelbarrow
– Concrete vibrator
– Trowel and spade
– Measuring tape
– Nails or screws
– Power drill
– Construction adhesive

3. Building the Frame:
Begin by building the formwork for your tank using the plywood or metal sheets. Cut the materials to the dimensions you’ve planned. Ensure that the formwork is strong and rigid to withstand the weight of the concrete. Use nails or screws to secure the pieces together. Apply construction adhesive to reinforce the joints. Leave openings for entry points, such as manholes and valve connections.

4. Reinforcement:
Place the rebar inside the formwork to provide support and prevent any structural failures. Position the bars vertically or horizontally, depending on the desired strength and design. Ensure that the rebar is securely fixed and won’t shift during the pouring of concrete. Use wire or zip ties to tie the bars together, ensuring they’re evenly spaced.

5. Mixing and Pouring Concrete:
Prepare the concrete mixture by combining cement, sand, and gravel or crushed stones in the appropriate proportions. You can use a concrete mixer or a wheelbarrow for this process. Add water gradually and mix thoroughly until you achieve a workable consistency. It’s crucial to have the concrete well-mixed to avoid weak spots. Pour the concrete into the formwork, ensuring an even distribution. Use a concrete vibrator to eliminate any air bubbles and achieve compaction.

6. Curing and Maintenance:
Allow the concrete to cure for a few weeks to achieve maximum strength. During this time, it’s essential to regularly spray water on the surface to prevent cracking and ensure proper hydration. Once fully cured, remove the formwork carefully to avoid damaging the tank. Inspect the tank for any cracks or imperfections and apply a suitable sealant if necessary.

7. Finishing Touches:
To ensure a smooth finish, use a trowel to level the top and sides of the tank. Consider applying a food-grade epoxy coating to enhance durability and facilitate easy cleaning and maintenance.

By following these steps, you can create your very own concrete tank for wine production. Remember to prioritize safety throughout the construction process and consult professionals or experienced winemakers for guidance if needed. With your new concrete tank, you’ll be able to enjoy the benefits of this resilient and effective winemaking vessel. Cheers to your successful wine-making endeavors!
