Top 6 Seijo Ishii Gourmet Must-Haves
1. Seijo Ishii French Roast Coffee Beans 450g × 6 Bags - ¥6,998 (~S$61.75)

Why it's #1: This isn't just coffee—it's the secret weapon of Tokyo's café culture. Seijo Ishii's French roast delivers that deep, bold flavor profile with low acidity and smoky undertones that coffee purists crave. The beans are roasted to a dark French profile (just before the second crack), creating an intense, full-bodied cup that stands up beautifully to milk while remaining smooth enough to drink black.
Singapore Price Comparison: Premium coffee beans at Jones the Grocer or Cold Storage's specialty section cost S$25-35 per 250g bag. For equivalent quality (2.7kg total), you'd pay S$270-378 in Singapore. You save S$155.25-263.25.
Roasting Profile Details:
- Bean Origin: Blend of Central/South American arabica beans (Colombia, Brazil, Guatemala)
- Roast Level: French (dark) - oil visible on bean surface
- Flavor Notes: Dark chocolate, toasted nuts, subtle caramel sweetness
- Acidity: Low (perfect for those who find light roasts too bright)
- Body: Full and rich, with velvety mouthfeel
Why Singaporeans Love It:
- Bulk Value: Six 450g bags (2.7kg total) means you're set for 3-4 months of daily brewing
- Versatile Brewing: Works beautifully in espresso machines, French press, pour-over, or cold brew
- Freshness Guarantee: Vacuum-sealed bags maintain freshness for 12 months unopened
- Gift-Worthy: Individual bags make excellent gifts for coffee-loving friends and colleagues
Brewing Tips for Singapore's Climate:
- Store unopened bags in a cool, dry place (air-conditioned room ideal)
- Once opened, transfer beans to airtight container and consume within 2-3 weeks
- Grind just before brewing for maximum flavor—pre-ground coffee loses aromatics quickly in humid weather
- For cold brew (perfect for Singapore), use 1:8 coffee-to-water ratio, steep 12-16 hours refrigerated
Taste Comparison:
- vs Starbucks French Roast: Seijo Ishii is smoother, less bitter, with more complex flavor notes
- vs Local Roasters: Comparable to specialty roasters like Nylon Coffee or Tiong Hoe, at half the price
- vs Supermarket Brands: Worlds apart—Seijo Ishii tastes freshly roasted, not stale or flat
2. Seijo Ishii Iced Coffee Liquid 1000ml × 6 Bottles - ¥3,980 (~S$35.13)

Why it's #2: In Singapore's eternal summer, this ready-to-drink iced coffee is pure convenience meets café quality. Seijo Ishii's iced coffee uses the same premium beans as their French roast, cold-brewed for 12 hours to extract maximum flavor while minimizing bitterness. The result? A smooth, naturally sweet coffee that tastes like it came from a specialty café, not a convenience store.
Singapore Price Comparison: Premium bottled coffee at FairPrice Finest or Cold Storage costs S$4-6 per 500ml bottle. For 6 liters (6000ml), you'd pay S$48-72 in Singapore. You save S$12.87-36.87.
What Makes It Special:
- Cold Brew Process: 12-hour extraction at 4°C preserves delicate flavor compounds
- No Added Sugar: Naturally sweet from the beans' caramelized sugars—add your own sweetener to taste

Why it's #4: These aren't your average supermarket croissants—they're made with French techniques and Japanese precision. Seijo Ishii's croissants feature 27 layers of laminated dough with 25% butter content (vs typical 15-18%), creating that signature flaky exterior and tender, honeycomb interior. Baked fresh daily in-store, then flash-frozen to preserve texture.

5. Seijo Ishii Coffee Jelly Dessert Cups 4-Pack - ¥650 (~S$5.74)
Why it's #5: This uniquely Japanese dessert combines Seijo Ishii's signature coffee with agar jelly for a refreshing, low-calorie treat. The coffee jelly has a firm, slightly bouncy texture (from agar, not gelatin), with a bittersweet coffee flavor that's perfectly balanced by the included cream topping.
Singapore Price Comparison: Coffee jelly at Japanese cafés like Tori Tori or Kuriya costs S$6-8 per serving. Four servings would cost S$24-32. You save S$18.26-26.26.

Seijo Ishii's version uses real brewed coffee (not coffee extract) and fresh milk (not creamer), creating a drink that tastes homemade, not factory-produced.
Singapore Price Comparison: Bottled coffee milk at FairPrice or 7-Eleven costs S$2.50-3.50 per 200ml. Twelve bottles would cost S$30-42. You save S$8.11-20.11.
