Yasuharu Takeuchi

I completed the second brew yesterday. The hop basket you made worked extremely well, and I was able to brew an IPA using homegrown hops.

Everything is functioning smoothly so far, and I think the brewing equipment is very well designed.

Thank you very much!

Best regards,

We couldn't be more impressed with the quality and service Wang and his team have provided us. Redwood Stainless engineers had no problem drawing and executing our custom tank design,which no one else would do. All of our tanks came outfitted with high quality fittings,valves,and carb stones. The welds are beautiful, and these fermenters are a real showpiece.
