Coffee or tea

If this copy was seen in York — or for this sake in the whole Britain — we would — after our recent expedition to Coxwold — surely say that this stain would be a stain of tea (Earl Grey). But since it appears in the danish edition Tristram Shandys levned og meninger (Borgen, 1976) sold from Holbæk Library — we more believe it is coffee. Though — since the Borgen 1976 edition was printed by The Whitefriars Press in London — we are not absolutely sure.
