Price comparison

wein.cc feed for Shopify

wein.cc (Die Wein-Suchmaschine) is the German-language wine price comparison that searches the range of over 300 wine merchants and shows current wine prices in real time. Feedflock turns your Shopify catalog into the WEINCCEXPORT XML file its specification defines (the four required fields mapped, gross euro prices, the real stock count) and hosts it on the stable URL their robot re-downloads every ten minutes.

To review: 4

Empty PRODUZENT on 6 winesThe Shopify vendor field is empty. Products without a producer are mostly ignored by wein.cc. Its FAQ names this as the usual reason an offer never appears.

No JAHRGANG on 9 winesShopify has no vintage field, so it ships empty. Wines that have a vintage are ignored when it is missing, so map it from a metafield or a variant option.

Sold-out wines still in the feed (4)wein.cc lists only LAGERSTAND>0, and presenting sold-out products pauses your whole presentation once they notice. The sold-out exclusion is switched off.

QUANTITY missing on 3 multi-packsOnly packs of 1, 3, 6 and 12 bottles are displayed. Without QUANTITY wein.cc expects the bottle count in the name, e.g. “(6 Flaschen)”.

Setup

Live in five steps

From a bare Shopify store to a listed offer: the whole setup fits into one coffee break.

Sign up with wein.cc
Registration is free, but onboarding is a signed CPC contract: fill it in, sign it and fax it or send a scan with your trade licence (Gewerbenachweis). Bids start at 15 cents per click, with no fixed costs and no contract binding.
Install Feedflock
Add Feedflock from the Shopify App Store. It reads your products, variants, stock and images directly through the Shopify API.
Pick the wein.cc template
Create a new feed and choose the wein.cc template. The four required fields (ARTIKELNUMMER, PREIS, PRODUKTNAME and PRODUKTURL) are mapped from the start, and PRODUZENT fills from your Shopify vendor.
Map the wine attributes
Shopify has no field for vintage, grape or bottle size, so JAHRGANG, REBSORTE and LITER ship empty. Map them once from metafields: wines without a vintage or producer are mostly ignored by wein.cc's editorial filter.
Paste the feed URL into the extranet
Enter the hosted feed URL in the wein.cc extranet under Profil. Their robot checks the file every ten minutes and downloads it whenever it changed, so there is nothing to re-upload.

The channel

The wine search engine

wein.cc automatically searches the range of over 300 wine merchants and vinotheques and shows current wine prices in real time, with 72% of its audience in Germany, plus Austria, Switzerland and Southern Europe.

A robot that checks every ten minutes

wein.cc's robot checks your export for changes every ten minutes and downloads it the moment it changes. With Feedflock regenerating the file every hour, a new price or vintage reaches the comparison on its own.

CPC from 15 cents, nothing else

Billing is per click with a minimum bid of 15 cents: no fixed costs, no contract binding, free registration. You can raise your CPC online at any time for a better ranking.

The feed

The template renders exactly the spec's XML: the WEINCCEXPORT root with its technik.wein.cc namespace, one PRODUKT per variant and the element order of wein.cc's own sample
All four required fields are mapped from the start: ARTIKELNUMMER from the SKU with the variant ID as fallback, so the unique key is never empty, and PRODUKTURL as a deep link that preselects the variant
PRODUZENT fills from the Shopify vendor (the field whose absence gets offers mostly ignored) with the full name and no abbreviations, as the spec asks
Vintage, grape variety, bottle size, region and country map once from metafields; nothing is guessed, because wein.cc removes wines with a wrong grape variety
LAGERSTAND sends the real Shopify stock count and sold-out variants are excluded by default: only LAGERSTAND>0 is listed, and a sold-out offer can pause your whole presentation
Prices go out gross with a dot decimal and no currency sign, and a multi-bottle pack carries the bottle price, exactly as the spec requires
KATEGORIE maps to the closed list of 24 wein.cc categories, comma-separated when a wine belongs to several, so a rosé sekt goes out as “Schaumwein, Rosewein”

Deep dive

How wein.cc reads your feed

One static XML file on a stable URL, entered in the extranet under Profil
Their robot checks it every ten minutes and downloads it only when it changed
Conditional GET via Last-Modified or ETag is a hosting property they explicitly ask for
Feedflock hosts the file on a stable URL and regenerates it every hour

Technical details

wein.cc pulls; the merchant hosts. The contract is explicit: you enter the URL of your price list in the extranet under Profil, and their robot checks your export every ten minutes, downloading the file when it changed and updating the data at wein.cc immediately. Their own example is a static file at an address like /export/wein.cc.xml.

That is precisely the model Feedflock provides: a hosted file on a stable URL, regenerated every hour. wein.cc also asks the hosting to support conditional GET with Last-Modified or ETag, a property of the hosting, not of the feed. You paste the URL once; there is nothing to upload again.

A vocabulary written for wine

22 elements, four of them required: ARTIKELNUMMER, PREIS, PRODUKTNAME, PRODUKTURL
Wine identity has its own fields: JAHRGANG, LITER, ALK, REBSORTE, LAND, REGION, ORT
PREIS is the gross euro price with a dot decimal, per bottle, never per case
LAGERSTAND is a stock count, not a status: only LAGERSTAND>0 is listed

Technical details

The format knows wine. Alongside the four required fields there are elements for vintage, bottle size in litres, alcohol content, grape variety, country, region and village or vineyard. PRODUZENT is not starred, but the editorial rules make it near-mandatory: products without a producer are mostly ignored, and the producer's full first and last name is requested.

The price is a gross euro amount with a dot as the decimal separator and no currency anywhere in the format, and for a multi-bottle pack it is always the price of one bottle. Availability is a number: LAGERSTAND carries the stock count, only counts above zero are listed, and the shopper sees bands like “sufficient quantity” above twelve.

Filtering instead of error messages

wein.cc publishes no validator and no error report: unsuitable offers are silently filtered
Dropped or edited: a missing producer, a missing vintage, a wrong grape, a “double vintage” like 2007/2008
Only packs of 1, 3, 6 and 12 bottles are displayed; promo words like “Aktion” are stripped from names
Two rules bind the shop itself: no minimum order or multiple of 6, and no popups on product pages

Technical details

wein.cc never tells you when it drops an offer. Its FAQ answers “why doesn't my product appear” with a paragraph on filtering: products without a producer are mostly ignored, wines without a vintage are ignored when they have one, wrong grape varieties get removed, double vintages are not shown and annotations like “Aktion” or “Sonderpreis” are edited out of names. Larger packs than 1, 3, 6 or 12 bottles are ignored outright.

Feedflock's template maps the fields these filters look at (producer from the vendor, the rest from metafields you set once) and excludes sold-out variants by default, since a sold-out offer can pause your whole presentation. Two rules no feed can fix bind the shop itself: wein.cc forbids a minimum order quantity or a mandatory multiple of six, and popups on the landing pages.

Categories and article numbers

KATEGORIE is a closed list of 24 values, from Rotwein to Weinzubehör
A product may carry several categories, comma-separated, order irrelevant
ARTIKELNUMMER is a stable unique key of at most 32 characters, never reused
One SKU across vintages or pack sizes is concatenated: 12345.2012.12

Technical details

Categories are not a tree but a closed flat list of 24 German names: Rotwein, Weißwein, Schaumwein, Rosewein (spelled without the accent), Likör/Süßwein and more, up to glasses and wine accessories. A product may belong to several, separated by a comma, and the order does not matter.

ARTIKELNUMMER is the offer's identity: unique, at most 32 characters, never changed and never reused for another product. If your shop reuses one number across vintages or pack sizes, wein.cc asks you to concatenate them: SKU 12345, vintage 2012, pack of 12 becomes 12345.2012.12. The template keeps the key on your SKU, falling back to the Shopify variant ID, which never changes.

The takeaway

One stable URL, an hourly refresh and an XML that follows the wein.cc specification field for field. Your Shopify catalog stays the single source of truth, and their ten-minute robot always reads its current state.

FAQ

Registration is free, but onboarding is not a self-service form: you sign the CPC contract and fax it or send a scan together with your trade licence (Gewerbenachweis). Bidding starts at 15 cents per click, with no fixed costs and no contract binding. Once the account is live, you paste your feed URL into the extranet under Profil.

Their robot checks your file every ten minutes and downloads it whenever it changed, updating the data immediately, and the merchant page advertises a shopper-side update once a minute. Feedflock regenerates the file every hour on the same URL, so each fetch reads current prices and stock.

PREIS is the gross euro price including VAT, with a dot as the decimal separator and no currency sign, as the format has no currency element at all. For a multi-bottle pack you always send the price of one bottle, not of the case.

They leave the feed. wein.cc lists only products with LAGERSTAND above zero, and presenting sold-out products leads to an immediate pause of your whole presentation once they notice. Feedflock excludes sold-out variants by default and sends the real Shopify stock count for the rest.

wein.cc filters silently instead of reporting errors. The usual causes are a missing producer, a missing vintage on a wine that has one, a wrong grape variety, a pack size other than 1, 3, 6 or 12 bottles, or promo wording like “Aktion” in the name. Feedflock's template maps producer, vintage, grape and pack size so these are one-time settings.

No. The 22-field vocabulary has no delivery-cost, delivery-time or carrier element at all. The only delivery statement is the editorial rule that products must be deliverable within a customary time. Delivery terms live on the wein.cc side, outside the feed.
