How Much Caffeine Does A Medium Tim Hortons Coffee Have? | Straight Facts

A medium Tim Hortons coffee has about 205 mg of caffeine in a 14-oz (425 ml) cup.

Caffeine In A Medium Tim Hortons Cup — By Size And Brew

Tim Hortons lists nutrition for calories and macros on its own tools, and third-party lab summaries compile caffeine numbers by size. Across those sources, a medium brewed cup lands at about 205 mg of caffeine. Small and large cups sit around 140 mg and 270 mg. Dark Roast trends a touch lower than Original Blend, while decaf shows only traces.

That 205 mg figure sits in the same ballpark as a strong home brew and falls below many large chain servings. If you’re sensitive, that single cup can still feel punchy, so timing and add-ons matter. Milk or cream won’t change the stimulant content, but extra espresso shots or a refill will push your daily total fast.

Quick Size-To-Caffeine Table

This chart gives a broad snapshot so you can gauge a typical cup at a glance.

Size	Volume	Caffeine (mg)
Small	10 oz (296 ml)	~140
Medium	14 oz (425 ml)	~205
Large	20 oz (591 ml)	~270
Extra Large	24 oz (710 ml)	~330
Dark Roast (Medium)	14 oz (425 ml)	~200
Decaf (Medium)	14 oz (425 ml)	~9–12

The numbers above reflect brewed cups poured in-store, not bagged coffee at home. Grind size, water temperature, and contact time can nudge the values up or down, but a medium shop brew stays near the 205 mg mark across days.

If you’re comparing across drinks, brewed coffee usually tops tea and many bottled pick-me-ups. For a broader sense of where your cup sits next to soda, tea, and energy cans, skim our in-house reference on caffeine in common beverages.

What 205 Mg Means For Your Day

Healthy adults in Canada have a recommended daily cap of 400 mg, which places a single medium well under the line. Two mediums land close to that limit. Those who are pregnant, planning to become pregnant, or nursing have lower recommended caps at 300 mg. Teens are better served by a weight-based ceiling. These reference points come from national guidance and help set a simple daily plan.

Many folks feel alertness within 15–45 minutes and hit peak effects within an hour or so. The stimulant sticks around for several hours. If sleep is fragile, front-loading your coffee earlier in the day pays off. Late-afternoon cups can push bedtime later without you noticing why.

Practical Intake Math Without A Calculator

Think in units. One medium brewed cup is roughly “half a day” for many adults. Add a tea, and you’re still fine. Add a second medium or an energy can, and you’re flirting with the ceiling. If you do want more, split the second serving with a friend or ice half for later.

For a clear, official reference on daily limits, see the Health Canada guidance. For a U.S. perspective that echoes the same cap, the FDA consumer update aligns with a 400 mg daily amount for most adults.

Why Medium Cups Vary A Little

Even when the menu says “Original Blend,” the exact milligrams shift a bit cup-to-cup. Freshness, grind, and the brew cycle play a role. If a pot sat a few minutes, that won’t change caffeine much, but a slightly finer grind or a slightly longer contact time can pull extra compounds from the grounds. None of that swings a medium from 205 mg to 300 mg, but a 10–15 mg drift is normal.

Original Blend Vs. Dark Roast

Roast level changes flavor more than stimulant strength. Darker roasts can read as stronger on the palate yet show a hair less caffeine in lab checks for this chain. That gap is small enough that your tongue will spot the difference long before your heart rate does.

Decaf Still Has A Little

Decaffeination pulls most, not all, of the stimulant. A medium decaf brewed cup often lands under a dozen milligrams. If you need a near-zero profile, herbal infusions or caffeine-free sodas fit better late at night.

Ordering Tips To Hit Your Sweet Spot

Small tweaks can dial the buzz without sacrificing taste. Pick one of these tactics based on how you feel after a normal medium.

Ways To Lower The Kick

• Go down one size. A small brewed cup trims about 60–70 mg.
• Ask for half-caf. Staff can blend brewed decaf with regular to soften the hit.
• Ice it and sip slower. Spacing intake smooths peaks.

Ways To Raise The Kick

• Add a single espresso shot to a small brewed base. Expect roughly +60–90 mg depending on shot size.
• Choose a large brewed cup instead of stacking two mediums.
• Keep sugar modest. Big sugar swings can mask how fast you’re sipping.

Brew Strength Factors You Can Control At Home

If you brew bagged Tim Hortons coffee at home, three levers shape stimulant pull: grind size, water ratio, and contact time. The shop’s in-store recipe aims for balance, so matching those levers keeps your mug close to the café profile.

Home Brewing Cheatsheet

Use this table to nudge strength without ruining flavor.

Factor	Change	Result
Grind Size	Slightly finer	More extraction; caffeine creeps up
Water Ratio	More grounds per cup	Stronger brew; higher mg per serving
Brew Time	Longer contact	Extra pull; watch for bitterness
Filter Type	Metal vs. paper	More oils through; taste shift, similar mg
Water Temp	195–205 °F	Steady extraction in the sweet zone
Serving Size	Smaller mug	Lower dose without taste trade-off

Timing Your Cup For Best Results

If sleep is the weak link, line up your brew with your wake window. Many people do well with a medium in the late morning and a lighter option after lunch. Skip caffeine within six hours of your target bedtime. Swapping that late cup for a decaf or a caffeine-free tea keeps the ritual without the toss-and-turn trade.

Stacking With Other Sources

Watch the add-ons that sneak into your day: pre-workout powders, colas, matcha, chocolate, and headache tablets. The sum matters. A medium brewed cup near 205 mg plus two cans of soda can nudge you into jitter territory even if each piece alone seems tame.

Comparing Medium Brewed Coffee To Other Picks

Chain-to-chain comparisons get messy, since brew ratios shift and some menus rotate seasonally. Still, a medium brewed cup from this chain sits in a middle lane. Many large coffees elsewhere run 300 mg or more, while smaller cappuccino-style drinks with a single shot sit closer to 75–100 mg. If you want a steadier curve, split your caffeine between a small brewed coffee and a tea later in the day.

Cold Drinks Aren’t Always Lower

Iced coffee can look milder but still pack a real dose depending on brew concentrate and ice. If you’re sensitive, iced tea or a flavored sparkling water keeps the chill without a stimulant surprise.

How To Read Menu Labels Without Guesswork

Store menus list calories, allergens, and macros far more often than caffeine. That’s normal. When caffeine isn’t printed, use the typical size-based ranges above and adjust based on how you feel. If a fresh pot tastes bold and you feel wired faster, you probably landed at the top of the range. If it tastes gentle and you feel only a mild lift, you’re likely closer to the lower end.

When To Cut Back

If you notice shakiness, headaches, or sleep trouble, scale down your dose for a week. Start by moving your cup earlier, then drop to a small, or blend half-caf. Most people feel better within a few days. If symptoms persist, switch to caffeine-free options and talk with a qualified clinician for individualized advice.

Bottom Line For Medium Brewed Cups

A medium brewed coffee at Tim Hortons lands near 205 mg of caffeine, with small, large, and extra-large cups stepping down or up in predictable increments. That makes menu planning simple: one medium in the morning fits most adult daily caps, while a second serving moves you close to the limit. If you need a lighter touch, drop one size or try half-caf. If you want more, pick one larger brewed cup instead of stacking several sugary picks.
