- 📦OLLA Brew Lab: Coffee Roast: now updating weekly4 updates in 30 days, after a quiet two months
- 📦OLLA Brew Lab: Coffee Roast updated to version 1.3.6OLLA 1.3.6 revises the Codex's varieties from their sources, works with iPhone Duo, and brings a new Roast to Cup home.
• Codex · varieties revised from sources: 254 entries in eight boards, 96 of them rewritten from sources; where accounts differ, who said what sits side by side, and claims without a source are gone. A new board, Names Without a Settled Pedigree, gathers bag names such as Sidra and Pink Bourbon that have no public breeding record to check, with who tested what. The 47 Robusta lines are checked against the World Coffee Research variety catalog; Red Bourbon merges into Bourbon and Javanica into Java, and the old names still search
• Find it, follow it, scan it: names are found with or without spaces and hyphens ("SL 28" and "SL-28" both find SL28); place names such as Harar and Kona link to the origin; label scan reads more variety spellings on bags and no longer takes the Java in Mocha Java for a variety
• Works with iPhone Duo: phone layout folded, tablet layout unfolded; folding, unfolding and turning never reopen the page, and the timer and anything half-written stay
• A new Roast home (OLLA Pro): one card each for green and roasted stock, with a trend line and this period's stock in, stock out and net; inventory value gets the same two cards. QC hold names green lots and batches separately and opens straight onto what is held; the inventory overview gains a Stocktake button
• Bean cards and forms: the Rest and Peak countdowns start from the roast date, or from the day the card was created when no roast date is filled in. Brew, bean card and cupping forms keep a draft, even when swiped away, and the keyboard no longer covers the field you are filling in
• OLLA Pro and fixes: on the free plan, tapping an OLLA Pro feature explains it right where you are instead of taking you elsewhere, and the OLLA Pro page now says the design workbench opens free, to dial targets and read the projection. Fixes include a cupping edit that could clear everyday flavors, and Chinese text in the date picker on English and Japanese screens… more - ✏️OLLA Brew Lab: Coffee Roast: description updated· CN

- 📦OLLA Brew Lab: Coffee Roast updated to version 1.3.5OLLA 1.3.5 重做了分享图,按来源重写了词典里的处理法,新增一期讲处理法的 LAB,浓缩可以记成一条冲煮记录。
• 分享图全部重做:豆卡、冲煮(滤泡与浓缩)、烘焙曲线、杯测、熟豆与生豆批次、评估、A/B 对照、烘焙对比与烘焙实验,现在用同一套版式。分享时选样式(实验报告或仪表)、浅色或深色纸,以及比例——4:5 或 1:1,豆卡、冲煮、烘焙曲线与杯测还有 9:16;选过的会记住。图上的数字与记录页一致,估算的萃取率标明是估算。价格、供应商、内部编号与盲码、库存量、评估者一律不上图。两支样品以上的评估归档后,多一张排名图。长的「档案」图不再提供,PDF 导出不变。分享图仍然免费;OLLA Pro 会在页脚加上你的店名与店标
• 词典 · 处理法整类重写,词条页列出来源:66 个词条分成八个板块,每一条都按来源重写,各方说法不一的地方并排写明是谁说的;新增共发酵、增味咖啡、肯尼亚式水洗等九个词条;重复与查不到来源的旧词条已合并或下线,没有出处的风味影响条与数字一并撤掉。有来源的词条页与板块页,页尾多了一份编号的「来源」清单,轻点一条打开原页,长按可以分享或复制地址。词条的别名可以直接搜到;英文与日文界面下,处理法与烘焙两类的卡片不再出现中文
• LAB 005「处理法:留下哪一层」:新的一期,十六章、九幅插画;第 01–07 章与第 15、16 章人人可读;第 08–14 章属于 OLLA Pro,包括讲新做法的几章、36 行的袋面写法对照表,以及 Best of Panama 2026 各批次的数据一章,各章里的批次表也随 Pro 打开
• 浓缩成了冲煮记录的一种方式:在记录里选「浓缩」,记粉量、出液量、出液时间(5–120 秒)和可选的 TDS;粉水比自动算出,填了 TDS 还会算出萃取率,这时判定只看萃取率;以前从浓缩实验室存下的记录照常显示为浓缩。新建表单会记住你上一次用的方式;这一版起存下的萃取率,旁边写明是实测、估算还是手填
• 处理法选项从 15 项增加到 33 项:豆卡、冲煮、杯测、烘焙、生豆与熟豆表单共用,分五组,每项带一句说明;清单里没有的可以自己输入,并按输入的原样显示;以前的记录照常显示。风味与口感的描述词现在也可以自己输入。拍照识别能认出更多袋面上的处理法写法,风味描述、水洗站名与广告语不再被认成处理法,各家所指不一的写法留空
• 工具、PDF 与修复:工具页每一格有一个小动作,读数不会因此移动,开启系统的「减弱动态效果」后只保留淡入。粉水比新增冰手冲、兑水(bypass)与冷萃浓缩三种算法,默认值与区间取自公开配方;冰手冲与兑水可以把要注的水量带进计时器,从那里记成一杯时,水量与粉水比按连冰或后加的水在内的总量记下。研磨度对照从 26 台磨豆机增加到 91 台,新增机型的档位大多取自第三方图表,是起手的位置。冲煮记录、杯测单、生豆批次与熟豆批次的单份 PDF,不再多出一张白纸或只有页脚的纸;评估(OLLA Pro)的成册 PDF,封面署这场评估的评估者,文件名跟随应用语言,分数一律两位小数,长记录与长索引换页后排得整齐,带店标的文件小得多;报告水印的选择重启后仍然保留。注水段数较多或屏幕较小时,计时器的按钮不再被底部标签栏挡住;冲煮记录里存下的萃取率按存下的值显示;从冲煮记录的弹层打开萃取率工具时改为全屏… more - 📈OLLA Brew Lab: Coffee Roast entered the top 100Top Grossing · Food & Drink · CN

- 📦OLLA Brew Lab: Coffee Roast updated to version 1.3.4OLLA 1.3.4 rebuilds the whole set of tools, checks the numbers in them against their sources, and rebuilds the ALO dossier in LAB.
• Tools as instruments: the timer tile shows your last cup with its brewer, dose, water, ratio, time and pour rhythm, and every other tile draws that tool's last reading; a tool you have not used yet shows its starting values marked Preset until a real reading replaces them; long-press to pin a tool, or arrange them from the menu; tap any number to type it, hold a stepper to keep adjusting, and adjust directly with VoiceOver
• Results that go somewhere: Extraction Yield shows its result on the Gold Cup chart, adds an immersion mode, opens from a brew record and writes TDS and extraction back to it, or logs a brew; Espresso Lab adds a stopwatch and three checks on time, ratio and extraction; Ratio adds a ratio ruler, two dose ranges up to 80 g and "Will it fit?", and carries dose and ratio into the timer; a scored Cupping Score sheet can be saved as a cupping record
• Water Recipe now works by two bottles: make a hardness bottle and a buffer bottle once, then get three weights for any batch from 0.25 to 5 L, or work back from a target hardness and alkalinity; recipes are rebuilt from their original sources, the estimated Third Wave Water Espresso recipe is removed, Lotus is shown by drops, Third Wave Water by sachet and SCAA 2009 as a benchmark. Grind Guide becomes one fine-to-coarse ruler drawn on the grinder's real dial, with settings from maker guides or a named chart and a converter that maps by brew method. Recipe Library adds search, filters and a pour-rhythm line, Flavor Wheel opens on its largest family, and Roast Reader and A/B Compare are tidied as well
• Numbers you may see change: on old records from French press, AeroPress, Clever, Switch and cold-brew makers where the beverage was not weighed, estimated extraction rises by about 3 points; the golden-cup range is now TDS 1.15–1.35% everywhere, so records between 1.35 and 1.45% no longer carry the golden-cup mark; the CVA total in Cupping Score rounds to 0.25; espresso preset names and parameters, water recipe amounts and grinder settings are corrected to their sources
• LAB · ALO dossier 2.0: rebuilt from re-verified sources in twelve chapters and fifty-six figures, and told mostly through tables and charts — the twelve stations one row each, methods by year, both auctions lot by lot, four Cup of Excellence editions, the record-price timeline and buyers by country; the station locations and the registered winner and prices of the 2021 Cup of Excellence are corrected, and claims with no recoverable source are withdrawn; free in full, charts included. The source lists of the Gesha and ALO issues now open at the end of each issue, with original and archive links; the Gesha issue and seven related entries are corrected to match
• Roast to Cup dashboard (OLLA Pro): the stock and cost tabs switch between trend and numbers, remembered on this device; stock numbers show the lot that runs out first, lots under their safety line, coffee roasted within 14 days and over 30 days, and in, out and net for the selected period; cost numbers show green and roasted value, value and share by origin or lot, and ageing; the headline's green half now shows weight on hand, like roasted… more - 🆕OLLA Brew Lab: Coffee Roast first spotted by AppInsider#24 in Top Grossing · Food & Drink · Indonesia
- 📦OLLA Brew Lab: Coffee Roast version 1.3.3OLLA 1.3.3 reorganizes origins and regions in the Codex, adds one LAB issue and rebuilds another, and makes roast inventory numbers more reliable.
• More complete regions: regions in Ethiopia, Kenya, Colombia, Costa Rica and Guatemala now follow each country's official coffee authority list, Panama's regions are rebuilt as well, Yirgacheffe's sub-regions are reorganized, and 41 new region entries join the Codex; country pages gather every region into one list, and 488 estates now link straight to their region
• Pick a region as you record: in bean cards, brews and cuppings, choose a country and then search for its region, or keep the country only; regions open their Codex entry, and share images, PDFs and labels now name origins the same way as the app
• LAB · Gesha, rebuilt: sixteen chapters and forty-six figures on its name and lineages, where it grows, and twenty-three years of Best of Panama prices; pick a lot, adjust the dose and roast loss, and see what one cup costs. Free in full, charts included
• LAB · Best of Panama 2026: a new auction dossier, free to read in full; the charts and lot-by-lot data on sales, scores and prices are part of OLLA Pro. Every LAB issue now opens with key points, one line per chapter, tap to jump to it; a small red dot on the Codex tab tells you when a new issue or a revision worth rereading is waiting
• Clearer, more reliable inventory (Roast to Cup, OLLA Pro): the inventory page opens on a stock overview — green and roasted on hand with their value, days of green cover, roasted coffee in its best window, and what needs attention; stock follows your latest count, costs use a moving weighted average, and totals match across screens, reports and exports; month close exports a spreadsheet, CSV and PDF and tells you when entries change after closing; a double tap no longer records twice
• The Weekly Cups card on Home keeps the same layout at any text size or display zoom, and Home no longer keeps the processor busy while it sits open, which saves battery… more - 🆕OLLA Brew Lab: Coffee Roast released on the App Store

About OLLA Brew Lab: Coffee Roast
OLLA Brew Lab is a coffee workbench for iPhone and iPad that keeps roast curves, brew logs and cupping records in one place.
It is made for home roasters, specialty coffee enthusiasts and small roasters.
Bean cards, brew logs and cuppings are free. In Roast to Cup, the roastery workbench for curves, roast profiles and inventory, the design workbench opens free; adding and delivering are OLLA Pro.
ROAST CURVES (OLLA PRO)
Log a roast live with large buttons for charge, yellowing, first crack and drop; development ratio and weight loss follow from what you record. Replay any curve, compare batches, and set a batch as your baseline. Import curve files in 11 formats; the source is detected from the file itself.
ROAST PROFILES: DESIGN BEFORE YOU CHARGE
Free: dial targets for first crack, drop and development ratio, and read the projected first-crack window, drop temperature and development ratio, with no machine connection. With OLLA Pro, save a design to the curve library, start a roast from it, or export it as .alog, JSON or CSV.
YOUR BEAN LIBRARY
One card per bag: origin, variety, process, estate, altitude, roast level, roast date, purchase details and your own notes. Resting and drinking windows count down on their own; a Home Screen widget shows a pinned bean.
Photograph a label, a bean list or a cafe menu and OLLA reads it on device, showing the words each field came from; nothing is saved until you confirm. On supported devices, Apple Intelligence fills gaps, corrects misreadings and adds explanations and translation in three languages, all on device.
The Coffee Codex holds 1,700+ cross-linked entries, from origins and varieties to processing and brewing.
BREW LOG
Record dose, grind, water temperature, ratio, TDS, extraction yield, timing and sensory impressions. The Tools tab sits alongside, with a step-recipe brew timer, an extraction-yield calculator and brewing-water recipes.
CUPPING
Score on a classic ten-attribute sheet, or use sensory scoring: cup profile, quality impression and five-cup consistency. Describe flavor with 16 everyday words or the full flavor wheel, and export a cupping sheet as a PDF.
OLLA Pro adds multi-sample blind assessment, with cup-by-cup records and a five-class verdict from L5 to L1.
FIELD GUIDE
City coffee guides, one volume per city, readable offline. Tokyo, Osaka, Kyoto and Fukuoka are published; the other cities on the city bar are marked Planned. Each list is selected from public data by OLLA's own scoring.
COFFEE JOURNAL
Beans, brews, cuppings and roasts stay linked, gathered in one archive with search, filters and yearly stats.
HOW PEOPLE USE OLLA
· A home roaster designs the next batch, logs it, and cups it a few days later on the same bean card.
· A specialty coffee drinker scans a new bag, watches its resting window and dials in a pour over.
· A small roaster keeps green and roasted stock, lot codes and labels in one ledger with OLLA Pro.

Latest updates
1.3.6
OLLA 1.3.6 revises the Codex's varieties from their sources, works with iPhone Duo, and brings a new Roast to Cup home.
• Codex · varieties revised from sources: 254 entries in eight boards, 96 of them rewritten from sources; where accounts differ, who said what sits side by side, and claims without a source are gone. A new board, Names Without a Settled Pedigree, gathers bag names such as Sidra and Pink Bourbon that have no public breeding record to check, with who tested what. The 47 Robusta lines are checked against the World Coffee Research variety catalog; Red Bourbon merges into Bourbon and Javanica into Java, and the old names still search
• Find it, follow it, scan it: names are found with or without spaces and hyphens ("SL 28" and "SL-28" both find SL28); place names such as Harar and Kona link to the origin; label scan reads more variety spellings on bags and no longer takes the Java in Mocha Java for a variety

1.3.5
OLLA 1.3.5 重做了分享图,按来源重写了词典里的处理法,新增一期讲处理法的 LAB,浓缩可以记成一条冲煮记录。
• 分享图全部重做:豆卡、冲煮(滤泡与浓缩)、烘焙曲线、杯测、熟豆与生豆批次、评估、A/B 对照、烘焙对比与烘焙实验,现在用同一套版式。分享时选样式(实验报告或仪表)、浅色或深色纸,以及比例——4:5 或 1:1,豆卡、冲煮、烘焙曲线与杯测还有 9:16;选过的会记住。图上的数字与记录页一致,估算的萃取率标明是估算。价格、供应商、内部编号与盲码、库存量、评估者一律不上图。两支样品以上的评估归档后,多一张排名图。长的「档案」图不再提供,PDF 导出不变。分享图仍然免费;OLLA Pro 会在页脚加上你的店名与店标
• 词典 · 处理法整类重写,词条页列出来源:66 个词条分成八个板块,每一条都按来源重写,各方说法不一的地方并排写明是谁说的;新增共发酵、增味咖啡、肯尼亚式水洗等九个词条;重复与查不到来源的旧词条已合并或下线,没有出处的风味影响条与数字一并撤掉。有来源的词条页与板块页,页尾多了一份编号的「来源」清单,轻点一条打开原页,长按可以分享或复制地址。词条的别名可以直接搜到;英文与日文界面下,处理法与烘焙两类的卡片不再出现中文
• LAB 005「处理法:留下哪一层」:新的一期,十六章、九幅插画;第 01–07 章与第 15、16 章人人可读;第 08–14 章属于 OLLA Pro,包括讲新做法的几章、36 行的袋面写法对照表,以及 Best of Panama 2026 各批次的数据一章,各章里的批次表也随 Pro 打开
• 浓缩成了冲煮记录的一种方式:在记录里选「浓缩」,记粉量、出液量、出液时间(5–120 秒)和可选的 TDS;粉水比自动算出,填了 TDS 还会算出萃取率,这时判定只看萃取率;以前从浓缩实验室存下的记录照常显示为浓缩。新建表单会记住你上一次用的方式;这一版起存下的萃取率,旁边写明是实测、估算还是手填
• 处理法选项从 15 项增加到 33 项:豆卡、冲煮、杯测、烘焙、生豆与熟豆表单共用,分五组,每项带一句说明;清单里没有的可以自己输入,并按输入的原样显示;以前的记录照常显示。风味与口感的描述词现在也可以自己输入。拍照识别能认出更多袋面上的处理法写法,风味描述、水洗站名与广告语不再被认成处理法,各家所指不一的写法留空
• 工具、PDF 与修复:工具页每一格有一个小动作,读数不会因此移动,开启系统的「减弱动态效果」后只保留淡入。粉水比新增冰手冲、兑水(bypass)与冷萃浓缩三种算法,默认值与区间取自公开配方;冰手冲与兑水可以把要注的水量带进计时器,从那里记成一杯时,水量与粉水比按连冰或后加的水在内的总量记下。研磨度对照从 26 台磨豆机增加到 91 台,新增机型的档位大多取自第三方图表,是起手的位置。冲煮记录、杯测单、生豆批次与熟豆批次的单份 PDF,不再多出一张白纸或只有页脚的纸;评估(OLLA Pro)的成册 PDF,封面署这场评估的评估者,文件名跟随应用语言,分数一律两位小数,长记录与长索引换页后排得整齐,带店标的文件小得多;报告水印的选择重启后仍然保留。注水段数较多或屏幕较小时,计时器的按钮不再被底部标签栏挡住;冲煮记录里存下的萃取率按存下的值显示;从冲煮记录的弹层打开萃取率工具时改为全屏
1.3.4
OLLA 1.3.4 rebuilds the whole set of tools, checks the numbers in them against their sources, and rebuilds the ALO dossier in LAB.
• Tools as instruments: the timer tile shows your last cup with its brewer, dose, water, ratio, time and pour rhythm, and every other tile draws that tool's last reading; a tool you have not used yet shows its starting values marked Preset until a real reading replaces them; long-press to pin a tool, or arrange them from the menu; tap any number to type it, hold a stepper to keep adjusting, and adjust directly with VoiceOver
• Results that go somewhere: Extraction Yield shows its result on the Gold Cup chart, adds an immersion mode, opens from a brew record and writes TDS and extraction back to it, or logs a brew; Espresso Lab adds a stopwatch and three checks on time, ratio and extraction; Ratio adds a ratio ruler, two dose ranges up to 80 g and "Will it fit?", and carries dose and ratio into the timer; a scored Cupping Score sheet can be saved as a cupping record
• Water Recipe now works by two bottles: make a hardness bottle and a buffer bottle once, then get three weights for any batch from 0.25 to 5 L, or work back from a target hardness and alkalinity; recipes are rebuilt from their original sources, the estimated Third Wave Water Espresso recipe is removed, Lotus is shown by drops, Third Wave Water by sachet and SCAA 2009 as a benchmark. Grind Guide becomes one fine-to-coarse ruler drawn on the grinder's real dial, with settings from maker guides or a named chart and a converter that maps by brew method. Recipe Library adds search, filters and a pour-rhythm line, Flavor Wheel opens on its largest family, and Roast Reader and A/B Compare are tidied as well
• Numbers you may see change: on old records from French press, AeroPress, Clever, Switch and cold-brew makers where the beverage was not weighed, estimated extraction rises by about 3 points; the golden-cup range is now TDS 1.15–1.35% everywhere, so records between 1.35 and 1.45% no longer carry the golden-cup mark; the CVA total in Cupping Score rounds to 0.25; espresso preset names and parameters, water recipe amounts and grinder settings are corrected to their sources
• LAB · ALO dossier 2.0: rebuilt from re-verified sources in twelve chapters and fifty-six figures, and told mostly through tables and charts — the twelve stations one row each, methods by year, both auctions lot by lot, four Cup of Excellence editions, the record-price timeline and buyers by country; the station locations and the registered winner and prices of the 2021 Cup of Excellence are corrected, and claims with no recoverable source are withdrawn; free in full, charts included. The source lists of the Gesha and ALO issues now open at the end of each issue, with original and archive links; the Gesha issue and seven related entries are corrected to match
• Roast to Cup dashboard (OLLA Pro): the stock and cost tabs switch between trend and numbers, remembered on this device; stock numbers show the lot that runs out first, lots under their safety line, coffee roasted within 14 days and over 30 days, and in, out and net for the selected period; cost numbers show green and roasted value, value and share by origin or lot, and ageing; the headline's green half now shows weight on hand, like roasted
