Strawberry Field vs. Strawberry Field Air: What's the Difference?
Strawberry Field and Strawberry Field Air are grown on the same farm in Doi Pukkood, Mae Hong Son, and roasted by Preda Roasting House (Lampang) using the same Yeast Dry Process x LTLH Drying base. The Air version adds an air-lock technique that regulates air pressure during fermentation, keeping the yeast calmer — shifting the cup from cape gooseberry and green apple toward juicier red apple and pineapple.
Are Strawberry Field and Strawberry Field Air From the Same Farm?
Yes. Both lots are grown on the same farm in Doi Pukkood, Mae Hong Son, at 1,200–1,400 meters above sea level, and roasted by the same team at Preda Roasting House in Lampang.
Both start from the same base process: Yeast x Dry Process combined with LTLH (Low Temperature Low Humidity) drying, which keeps air temperature below 40°C and relative humidity between 30–60% to prevent mold and off-flavors from over-fermentation. They aren't two unrelated coffees that happen to share a name — they're sibling lots that diverge at a single fermentation step.
What Is the Air Lock Technique in the Air Version?
The difference in Strawberry Field Air comes down to controlling air during fermentation. Preda's process team calibrates the ratio of air to raw material to starter yeast, then fits an air lock onto the fermentation tank to keep internal air pressure balanced throughout.
The result is a calmer, more consistent fermentation environment for the yeast than the naturally air-exposed dry process used for the original lot. The team's own shorthand for the goal is keeping the yeast "unstressed" — a single adjustment to the fermentation tank's environment, not a change to the farm, variety, or roast level.
How Different Do the Two Coffees Actually Taste?
Strawberry Field (the original) delivers strawberry, cape gooseberry, and green apple notes with a light, clean body and a long, sweet finish. Strawberry Field Air delivers strawberry, red apple, and pineapple, with a softer acidity and good balance.
Strawberry aroma in coffee comes largely from ester compounds (such as ethyl butanoate and ethyl hexanoate) that form during fermentation. The more tightly fermentation conditions are controlled, the more that shifts which esters form and in what proportion — the likely chemical reason the two lots land on different fruit notes.
Do Price, Size, or Brewing Recommendations Differ?
Both are priced in the same range, roughly ฿350–฿1,400 depending on size (100g / 200g / 500g), and both are roasted light. The Air version isn't priced higher despite its more tightly controlled fermentation.
For brewing, the original is recommended as a drip with 89–90°C water at a 1:15 coffee-to-water ratio. The Air version is recommended at 87–90°C and works across more methods — drip, espresso, or iced drip — since its softer acidity holds up better under a hotter, more intense extraction.
Which One Should You Choose?
If you prefer a bright, straightforwardly tart-sweet fruit character — cape gooseberry and green apple — go with the original Strawberry Field. If you prefer a juicier, riper fruit sweetness with softer acidity, Strawberry Field Air is the better fit. And if you're curious how much a single fermentation adjustment can shift the cup from the same farm, trying both side by side is the best way to find out.
Frequently Asked Questions (FAQ)
Q1. Are the two coffees the same variety?
The product page lists Bourbon and Catimor specifically for the Air version; the original doesn't list a variety separately, though both are grown on the same farm at the same altitude.
Q2. What does LTLH stand for?
LTLH stands for Low Temperature Low Humidity Drying — drying coffee at air temperatures below 40°C and 30–60% relative humidity to prevent mold and off-flavors from over-fermentation.
Q3. Are both coffees registered with Thailand's FDA?
Yes. Strawberry Field carries Thai FDA registration 52-2-03266-6-0001, and Strawberry Field Air carries 52-2-0326-6-6-0035.
Q4. Is one more expensive than the other?
No, both fall in the same ฿350–฿1,400 range depending on size (100g/200g/500g). Check the product page for the exact current price before ordering.
Q5. Where can I buy them?
Both are available directly from their product pages on the Preda Roasting House website.
