    "content_text": "Leibniz Butter Biscuits: The 52-Tooth Original, in summary: Leibniz is Bahlsen's plain butter biscuit, first baked in Hanover in 1891 and still the toothed rectangle with 52 teeth. It is crisp rather than short, takes a quick dunk and makes a firm dessert base.\nLast reviewed by the teas.co.uk team in September 2026.\nThe Leibniz biscuit is older than the German word for biscuit: Bahlsen coined Keks in 1911, twenty years after the first Leibniz came out. It is still the reference point for the plain butter biscuit, crisp, golden and deliberately undecorated.\nA polymath's name and a toothed edge \nHermann Bahlsen founded his company in Hanover in 1889 and launched the first Leibniz biscuit in 1891, naming it after Gottfried Wilhelm Leibniz, the city's celebrated polymath. Two years later it won a gold medal at the World's Fair in Chicago. Bahlsen is still family-owned and still based in Hanover, and the biscuit is still a flat golden rectangle with its name pressed into the centre.\nThe toothed edge is the signature: the brand says the original is only genuine with 52 teeth. It is practical as well as recognisable. A notched rim chips less in the packet than a straight cut, breaks more cleanly in the hand and leaves a ridge to grip so fingers stay off the flat surface. Freshness was thought about early too; in 1904 Bahlsen introduced the TET pack, a cardboard pack made to keep the biscuits fresh.\nButter biscuit, not shortbread \nPeople often file Leibniz beside shortbread, but the two are built in opposite ways. Shortbread carries a lot of fat against its flour and crumbles or melts under pressure. A butter biscuit is drier, crisper and stronger, so it snaps with an audible break. The published ingredients bear that out: wheat flour leads, then sugar, then butter at 12%, with whole milk powder and egg powder further down the list.\nThat strength is what makes it useful beyond the tin. Crushed and bound with melted butter, it makes a cheesecake base that stays firm under a wet filling, better in our view than a digestive. It carries a slice of cheese without snapping in half, and it sits happily under something sweeter, such as fruit or a spoonful of jam, because its own sweetness is kept in check.\nDunking, tea and keeping it crisp \nLeibniz takes a dunk, but a short one: a second, two at the most. It holds together longer than a rich tea, yet it is thin and dry, so once hot tea soaks in it goes all at once. Give it a strong cup with milk, such as an English Breakfast or an Assam. The dry, clean break works just as well beside a milky coffee, or beside Earl Grey at eleven.\nButter is the only flavour, so freshness decides everything; once a Leibniz softens there is no chocolate or filling to rescue it. Keep the pack sealed, or tip the biscuits into an airtight tin once it is open, and buy the size you will finish. If you want chocolate on top, Choco Leibniz sits in our Bahlsen range. This plain one is the everyday original, and the one to keep in the cupboard.\nThe packs we stock \n\nLeibniz Butter Biscuits, 200g (barcode 4017100370007)\n\nWhat the label says \nThe published ingredient list for Leibniz Butter Biscuits, 200g says it contains wheat (gluten), milk and egg.

The toothed edge is its signature, and the brand says the original is only genuine with 52. The notches also make the rim less likely to chip.\nWho was the Leibniz biscuit named after? Gottfried Wilhelm Leibniz, the Hanover polymath. Bahlsen named its first butter biscuit after him in 1891.\nWhat allergens are in Leibniz Butter Biscuits? Per the published ingredient list it contains wheat (gluten), milk and egg. Check the current UK pack, as recipes and allergen advice can change.\nCan you dunk a Leibniz? Yes, briefly. One or two seconds in a strong tea is enough before the thin biscuit starts to give.\nIs Leibniz the same as shortbread? No. It is a crisp butter biscuit that snaps, whereas shortbread is richer in fat and crumbles.\nCurator's note: This is the biscuit to reach for when the tea matters more than what comes with it. Plain, crisp and gone in two bites, which is exactly its job.
