Fröccs is a refreshing Hungarian wine spritzer that is perfect for hot summer days in Budapest. It is made by mixing white wine with sparkling water, and it is typically served in different ratios, ranging from small to large fröccs. The most popular variations include the 'kisfröccs' (small fröccs) with a higher wine to water ratio and the 'nagyfröccs' (large fröccs) with a higher water to wine ratio. Fröccs is a popular choice among locals and is often enjoyed at outdoor bars and terraces.
