Quality Standards
Every drink that leaves the counter represents Muse & Co. A sloppy-looking drink or an inconsistent flavor tells the customer we do not care. This page covers the standards every drink must meet before it goes to the customer. If a drink does not meet these standards, remake it.
The Golden Rule
When In Doubt, Remake It
If you look at a finished drink and think "that does not look right" or "I am not sure I made that correctly," remake it. The cost of one wasted drink is far less than the cost of a disappointed customer who does not come back. Never serve a drink you would not want to receive yourself.
Ice Standards
| Standard | Details |
|---|---|
| Default | Ice, then top up the mixing cup to 500 (regular) / 600 (large) |
| Hot drinks | No ice; top up with hot water to the same line |
| Light / half ice | Brew to 250 / 350 instead of 200 / 300, then ice and top up |
| No ice | No ice; top up to the line with tea or water |
| Ice quality | Use fresh ice only. If ice has been sitting out and is partially melted or clumped, use a fresh scoop |
"Light Ice" and "No Ice" Affect the Drink
When a customer asks for light ice or no ice, the drink will taste slightly different because there is less dilution. That is expected. Keep the creamer, powder and sugar the same; only the brew and ice change. See How Every Drink Is Built.
Sweetness Consistency
Every team member should make the same drink at the same sweetness level. Sugar is liquid cane sugar weighed in grams from the dispenser, never eyeballed. Regular sweetness (100%) is 15 g for a regular drink and 20 g for a large; the full table is on How Every Drink Is Built.
Always Confirm Ambiguous Requests
If a customer says something vague like "a little less sweet," confirm which level they want (the register offers 0%, 25%, 50%, 75% and 100%). Do not guess. Getting the sweetness wrong is the number one reason for remakes.
Topping Portions
Consistent topping portions ensure the drink experience is the same every time.
| Topping | Standard Portion | Method |
|---|---|---|
| Tapioca Boba | Regular: scoop ¾ full. Large: scoop full, not heaped | Use the boba scoop |
| Popping Boba (Peach, Passion Fruit) | 1 tablespoon | Use the small spoon |
| Jelly (Strawberry Heart, Lychee, Mango Star) | 1 tablespoon | Use the small spoon |
| Cream Cap (Classic or Sea Salt) | A visible layer across the top | Spoon onto surface -- see Cream Caps |
| Coffee Jelly | 1 tablespoon | Use the small spoon |
| Marshmallow | 2 on a skewer, drizzled with chocolate sauce | See Hot Chocolate |
Do Not Over-Portion or Under-Portion
Too many toppings and we lose money. Too few and the customer feels shortchanged. Use the designated serving utensil for each topping and stick to the standard portions.
Lids
We don't seal cups with film. Every drink gets a lid:
| Drink | Lid |
|---|---|
| Cold drinks (white/clear cup) | Dome lid (room for toppings and cream caps) |
| Hot drinks (black cup) | Flat lid |
Press the lid on all the way round and wipe the rim first if it's wet. Hand over a drink only if the lid is on firmly and the cup is clean outside.
Presentation Standards
Visual Checks Before Serving
Run through this mental checklist before every drink goes to the customer:
- [ ] Color looks correct for the drink ordered (deep orange for Thai Tea, purple for Taro, green for Matcha, etc.)
- [ ] No clumps of undissolved non-dairy creamer or drink powder visible
- [ ] Boba is visible at the bottom (for boba drinks)
- [ ] Cream cap is floating on top as a distinct layer (if ordered)
- [ ] Tiger stripe swirl is visible (for Brown Sugar Milk Tea)
- [ ] Cup is clean on the outside -- no drips, no sticky syrup, no smudges
- [ ] Lid is on firmly and the rim is clean
- [ ] Straw provided (or available at the pickup counter)
Drink-Specific Presentation
| Drink | What to Look For |
|---|---|
| Brown Sugar Milk Tea | Visible tiger stripes on cup walls, not stirred |
| Taro Milk Tea | Consistent purple color, no white clumps |
| Matcha Latte | Vibrant green, fully mixed or intentionally layered |
| Thai Tea | Deep creamy orange, not pale or brown |
| Cream Cap drinks | Cap floating on top, not mixed in |
| Macchiato Latte | Visible layers, caramel drizzle on top |
| Special Brewed Teas | Clean glass teapot, served on saucer with tea cup |
| Blooming teas | Bloom should be opening or open when delivered to table |
Temperature Standards
| Drink Type | Ideal Temperature |
|---|---|
| Iced drinks | Cold throughout, ice not fully melted |
| Hot lattes and coffee | 150-160F (hot but not scalding) |
| Hot chocolate | 150-160F |
| Special brewed teas | Served in hot teapot, water at the correct temp for the tea type |
Do Not Let Drinks Sit
Once a drink is finished, it should go to the customer within 1-2 minutes. An iced drink that sits on the counter for 5 minutes has melting ice (diluted), sinking boba (clumpy at bottom), and a cream cap that is starting to dissolve. A hot drink that sits gets cold. Call the customer's name or number promptly.
What to Do When Something Goes Wrong
Customer Complaints
If a customer says their drink does not taste right or is not what they expected:
- Apologize -- "I am sorry about that, let me fix it for you"
- Ask what is wrong -- too sweet, wrong flavor, wrong drink entirely?
- Remake it without hesitation. Do not argue or try to explain why it is correct
- Let the shift lead know if there is a pattern (multiple complaints about the same drink)
You Notice a Problem Before Serving
If you catch an issue before the drink reaches the customer:
| Issue | Action |
|---|---|
| Wrong drink made | Discard it and start over |
| Wrong sweetness level | Remake from scratch (you cannot fix sweetness after the fact) |
| Clumpy powder or undissolved ingredients | Remake -- straining is not reliable |
| Lid won't sit right | Use a fresh lid |
| Cup is dirty or cracked | Transfer to a new cup, or remake if the drink has been contaminated |
| Stale boba (past 4 hours) | Discard the boba batch and cook fresh |
| Cream cap is watery or separated | Make a fresh cream cap batch |
When to Escalate
Some issues need management attention:
- Equipment malfunction (tea machine, coffee machine, blender, hot water dispenser)
- Running out of a key ingredient with no backup
- Multiple customer complaints about the same drink in one shift
- Food safety concern (spoiled milk, contaminated ingredients)
Cleanliness Standards
| Area | Standard | Frequency |
|---|---|---|
| Prep counter | Clean and dry, no sticky residue | Wipe after every drink |
| Boba station | No spilled boba, syrup cleaned up | After every few drinks |
| Tea brewing area | No loose tea leaves on the counter | After each cup brewed |
| Espresso machine | Wipe down exterior | As needed (fully automatic machine -- no manual steam wand or purge) |
| Cups and lids | Stored in clean, covered area | Always |
| Utensils (ladles, spoons) | Rinsed between uses, sanitized hourly | Ongoing |
Clean As You Go
The best way to keep the workspace clean is to wipe up small messes immediately instead of letting them accumulate. A 5-second wipe after each drink prevents a 15-minute deep clean later.
Consistency Is Everything
The goal is that a customer gets the exact same experience whether they come in Monday morning or Friday night, whether you make their drink or a coworker does. That only happens if everyone follows the same standards, uses the same portions, and holds the same bar for quality. When we are consistent, customers trust us, and trust brings them back.
