Never have, but my assumption is that the concentrated flavor from the long steep time would mask any slight change the hot water might add. However, could be fun to have a thing of extra concentrated cold brew and a separate thing of hot water prepared coffee and combine the two before drinking. Play around with the ratios a bit to find the dopest mixture 🤌

I did this for about a year. Argument was the hot bloom could pull out some parts of flavor that the cold brewing couldn’t. I recently switched back to cold-only and decided the brews were improved. I do 100gm:700gm ratio and let it steep 24 hours.
