Light and Crisp
KEEP REFRIGERATED ❄
Coffee, reimagined. Real espresso meets slow-extracted Lion's Mane in a flavor that doesn't split the difference—it's its own thing. Layered with earthy depth and a whisper of natural vanilla, Light and Crisp is built for sustained executive focus.
Storage: hydrbrew° should be stored in the fridge so it's ready to chill whenever you need it.
Ingredients: Purified Water, Espresso Coffee Concentrate (Water, Arabica Coffee), Organic Coconut Sugar (3g), Natural Coffee Flavor, Magnesium Chloride, Lactic Acid, L-Theanine (200mg), Organic Lion's Mane Mushroom Extract (200mg), Potassium Chloride, Salt, Natural Vanilla Flavor.
Questions we hear a lot.
That’s by design. hydrbrew° isn’t competing on roast intensity. The 85mg
caffeine dose sits at the calibrated activation point, enough to support
executive function, without tipping into the cortisol spike that makes
stronger-tasting drinks crash harder.
Because more caffeine isn’t the same as better focus. Paired with 200mg
L-Theanine at a 2:1 ratio, the 85mg dose is calibrated for sustained, precise
output — not a short, sharp spike.
Functionally, yes — and that’s the point. Coffee is the vehicle. The
nootropic and adaptogen stack (L-Theanine, Lion’s Mane, electrolytes) is the
actual product.
Same cold-brew soul, engineered so caffeine arrives buffered rather than
as a spike. L-theanine and Lion's Mane are dosed in to keep the lift from
turning into a jitter, or a crash two hours later.
Because more caffeine isn't the same as better focus. Research shows
cognitive benefits peak around 50–85 mg, not at the top of the dose range. 85 mg
is calibrated to that peak, enough for sustained executive function without
tipping into the cortisol response that causes the crash.
No. Energy drinks are built to maximize stimulation. hydrbrew° is
calibrated to a research-backed dose threshold, a deliberately different
design goal, not a stronger or weaker version of the same thing.
Light, crisp, and clean, a low-acid coffee base, not a heavy or syrupy
finish.
