This page carries food-allergen labeling information. Gluten-free claims and religious dietary exclusions are decided by different criteria.
Differences between stores
The published material says nothing about differences between stores. Saying nothing is not saying there are none.
This page covers nationwide mail-order products and does not mention any difference by point of sale. However, café items such as pancakes and crepes offered at a handful of locations, including the Ohiradai flagship store, are served store by store and are not covered by this page.(machine translation)

このページは全国共通の通信販売商品を対象としており、販売場所による記載内容の違いはありません。ただし、大平台本店をはじめ一部店舗に併設されたカフェで提供されるパンケーキやクレープなどのメニューは店舗ごとの提供で、このページの対象外です。

- Notes for reading
(1) Each product's allergen line reads like 'contains a portion of egg, wheat, milk, soy, orange', naming the substances present in that product. A substance named there is present, but a substance NOT named is not declared absent, and this site does not treat it as absent either. (2) Aoume Hitoshizuku has no visible allergen line at all, so this site could not confirm its contents. (3) The mini almond butter cake and the classic gâteau chocolat note they are made on equipment also used for products containing peanuts or walnuts. (4) This page only covers mail-order products. Café-only items such as pancakes and crepes served at a handful of café locations are outside this page and need to be checked in store. (5) No version number or confirmation date is visible on this page. (6) No statement anywhere on the page declares which allergen items are checked for (the mandatory 8/9, the recommended 20, or otherwise), and no legend or symbol definitions were found. The page is a free-text description per product rather than a table, so there is no column-based scope either.

(1) 各商品のアレルギー欄は「一部に卵・小麦・乳成分・大豆・オレンジを含む」のように、その商品に含まれる物質を列挙する書き方です。ここに名前が挙がっている物質は使用されていますが、挙がっていない物質について「使用していない」と宣言されているわけではなく、当サイトとしても不使用とは判断していません。(2) 「青梅のひとしずく」にはアレルギー物質の記載欄自体が見当たらず、当サイトでは内容を確認できていません。(3) アーモンドバターケーキミニとクラシック・ガトーショコラには、落花生やくるみを含む製品も製造している設備で作られている旨の記載があります。(4) このページに掲載されているのは通信販売の物販商品のみです。カフェを併設する一部店舗のパンケーキやクレープなどのメニューはこのページの対象外で、店頭等での確認が必要です。(5) このページに版番号や確認日時の記載は見当たりません。(6) ページ全体を通じて、確認対象品目(義務8/9品目・推奨20品目等)の宣言や、凡例・記号の定義は見当たりません。表(マトリクス)形式ではなく商品ごとの自由記述であるため、列という形の対象範囲もありません。
- Legibility notes
The page is plain text, not an image or PDF, so it reads normally without special handling.

Allergy notes
The official online shop's ingredients page lists, for each of its main mail-order products such as the baumkuchen and biscotti, the raw materials together with an allergen sentence in the format '(contains a portion of ...)'. The page does not state which substances it checked for or how complete the product list is, so neither a product missing from the page nor a substance not named in a product's sentence can be treated as confirmed absent. Some products note they are made on equipment also used for products containing peanuts or walnuts. This list covers mail-order products only; café-only items such as pancakes and crepes served at a handful of café locations are not covered.
