Apax Lab products have been a game changer for my drip coffee at home. I’ve experimented with Brita filters, bottled spring water and distilled water with Third Wave Water added and nothing comes close to Apax drops. So far I’ve used Lylac and Tonik and they’re both incredible at elevating sweetness, clarity and texture. It’s nice to not have to worry about water quality as a variable in my brewing. I can’t recommend enough!
