About us
Read stories from partners who've grown their business with Hardtank's solutions. See how our technology, expertise, and support make the difference from day one.
"This is where having a specialist partner added real value. We know our brand and our customer, but RTD production comes with a different set of technical and regulatory requirements, and Hardtank helped us navigate this at every step. It was important that the final product still looked and felt unmistakably Arctic and our final product absolutely achieved that. For anyone considering a custom RTD, Hardtank offered experience, practical support, and advice on how to deliver our goals. It allows companies to dream big!"
"Hardtank provided a template and all the information we needed in order to create a beautiful packaging. They provide nutrient information and all the data we need to be fully compliant with our local regulations. Looking at packaging, basically, we only had to design the labels for our cans and Hardtank took care of the rest."
"We stay fully in control of the recipe, design of the label, and Hardtank brings the expertise on canning, pasteurisation, and the legal and nutritional side of putting a beverage on the market. That division of labour has worked really well. We could develop the product our way, and the quality of what comes out is something we are genuinely happy to put our name on."
We decided to work with Hardtank because they had the expertise required to ensure that the cold brew they produced met the expected standards in terms of quality, taste, and aroma, using coffee roasted by us. Thanks to this, we have been able to avoid investments in equipment as well as additional personnel costs. It is also worth highlighting that, production after production, the quality of the finished product—in terms of taste, appearance, and aroma—has always remained consistent. This is something we really appreciate.
“In less than 2 hours, we can get the bold flavours, the notes of complex speciality coffee that we were looking for. We worked with Hardtank not just to delegate production complexities but also because the company’s groundbreaking technology helps reduce the brew time from 24 hours to under two hours while enhancing the flavour profile of the cold brew.”
"Before investing in the Hardtank, the production process was quite a labour-intensive and inefficient operation, especially as it began to scale up. The Hardtank has been a game-changer, offering a controlled brewing environment that ensures consistency across multiple batches. The Hardtank’s automated process has massively reduced the amount of hands-on work needed to produce cold brew."
“We started by using Baby Hardtank at an international food fair, and did some fascinating showcases extracting cold coffee. We realised we could do cold brew extraction as well as infusing fruit to create signature drinks that were highly appreciated – and it was very aesthetically pleasing.”
“Brewing in the fastest time, clear coffee, unique flavors and extremely high beauty.”
“The quality, solid and real dedication to create the best equipment to have the best cold brew in every subject is what made my experience with Hardtank really great. I have been following them for a long time, and now I have my Hardtank for my cold brew brand, and it is going so great. Cleaner, faster, versatile… great. Easy to use, easy to clean, easy to connect. I’m even having better profit because of the quantity of cold brew coffee I need to produce.”
“It’s a pleasure to work with Hardtank. Hardtank gives me an opportunity to diversify the approach of extracting things. I’m not limited to a boring menu. I’ve always thought of Hardtank not only in coffee context…For me it has a great potential in cocktail bars.”
"We like that Hardtank is developing new formulas and new drinks, like the vegan matcha latte. That’s one of the good things, because there are specific recipes companies can use for their private label drinks. It makes it easy for the people buying those drinks, and then selling them to customers, to explain exactly what each drink is. The Hardtank team is very precise with what they offer."
“Hardtank is a very thoughtful equipment which crates a wide pallet of drinks and allows your flight of imagination. It is a real game changer!”
“Anyone who has experienced and witnessed the cold brew production from Hardtank knows that it is the best solution in the market.”
“Hardtank redefines the cold brew experience by opening new creative possibilities. Not only is it incredibly user-friendly, but it also amazed me with the variety of innovative beverages I could create—from coffee to tea and herbal infusions.”
“Hardtank was the first choice, which simply caught our eye. Once we saw this is a Polish company, we already knew that we were going for it. We started in the summer season with flat white based on dark roasted beans that we brewed with Hardtank, and it was a total hit. Following [Hardtank’s] advice, we mixed it in the right proportions with oat milk.”
